I knew Tasmania was much older than the Eastern seaboard of Australia, but I never realised just how far it has travelled over the eons. That was really interesting, thanks.
Since it was a thousand million years ago, things are not so clear. There are different models. Some models claim Tasmania travelled to southeast Australia (Pisarevski et al., 2003), whereas some others proposed that Tasmania stayed at about the same spot relative to Australia, as it was the original junction point of Australia, Antartica and Laurentia (North America) (Hoffman, 1991, Pisarevski et al., 2003)

Hi from Chevy Chase MD! Apparently the western arm of the Midcontinent Rift has been found to extend as far as TX. This is important in N. American geology because if the rift had not failed, there might be an ocean--or least geological evidence of a past ocean in mid-America today. This leads to the exciting probability that at least part of Texas was connected to Antarctica. I say this because rocks from the Midcontinent Rift are a match with rocks in Antarctica.
@@harrietharlow9929 There is plenty of evidence for multiple periods of oceanic sedimentation in “mid America.” In fact, virtually every sedimentary rock (sandstones, shales, limestones) in North America was deposited in a marine environment. Magmas that were deposited within the mid-continent rift often show “pillow structures,” indicating that at least some were erupted under water, which makes sense; look at the Red Sea - when continental crust rifts apart, any nearby ocean will fill the rift if it can obtain access. As far as “rocks matching” between Texas and Antarctica, do you mean rock type, continent shape (which has changed drastically over the years), fossil content, geochemical signatures, or what?
This is absolutely amazing! The fact that Tasmania is not only an island but it’s also its own continent that is connected to an island that is also a continent.

Most of us Tasmanians have always known that Tasmania is a continent and Australia is an Island connected to Tasmania, so this is nothing new for us Tasmanians, but for you other peoples, well you have learnt something 😊
Thankyou once again. Nice. This has peeked my interest again. As you know I was a petroleum geologist and did a alot of work in the Bass Strait, between Tassi and Victoria, Australia's most prolific oil and gas fields. For this we needed to work out the geologic history but only so far back as say the splitting of Gondwana starting about 180 mya. Part of this is as you say the splitting off of Antartica (I did do a project to see if the Eyre Basin offshore SW of Adelaide in the Australian Bite would be economic for oil and gas and this was heavily influenced by that split, was great to do). Tassi was an aborted attempt at that split, that is what formed the Bass Strait and the structral settings for the oil and gas to accumultae, much like the North Sea was an aborted Atlantic, giving rise to the oil and gas there. The land bridge you talk of is much later say the last 100,000 to 2000yrs (latter no a guess ie geolicially so small a time ago that it is almost today anyway and the structures in that regard have not moved so the flooding of that narrow bridge of land was totally due to sea level rise as the ice metled after the last age, not plate tectonics, ie land sinking etc, have to be careful on this on the UK the land sunk due to the ice and then rose and is still rising in the NW half of the UK due to the ice melting and sinking on the SE half, that is one reason the Thames Barrier had to be made, plus sea level rise recently due to global warming. But there I think was so little ice in Tassie and Victoria this would not be anywhere near as significant in Tassie, so I'm dismissing that as a cause for flooding of the bridge). One guy below reckons Tassie was between America and Scotland in Nuna times, that has got me pondering. Scotland was joined to America back then but choofed off eventually to join Europe (Im goijng to check my Uk book now and will get back to writing this after). Ive checked that now, Scotland joined Euope, well England and Wales (Avalonia). That was much later about 400mya. SO Tassie could well have been joined to America in a position close to where Scotland was in the Nuna continent, say 1.6 BYA (1600Mya). Hmmm! Where is Eurpoe and Asia in that Nuna Map shown here, it seems missing. From wikki it maybe in that brown blob down the left hand side labelled as Ameirca. That is where it appears in Wikki. So loads could have happened between 1600 mya of Nuna and Scotland joining England and Wales (Avalonia) as they crashed into America (500Mya). In the meantime Tassi had gone a wondering away to Antartica (again) and Australia (which became joined) to get stuck between the two. Its a bloody teaser. There are some good short youtuubes on Tassi and this one from Hobart Uni. Ill see if I can find them and re watch them. I have to keep going over this stuff to see it in my minds eye and get it correct, its a 4D jig saw puzzle. Love it. Thanks Ah ha, found one of the ones I was talking about heres the link th-cam.com/video/_f_Hcyfv5rU/w-d-xo.html Also when searching for that came across this, it says that the Kimberly region of WA Australia was also part the American continent Luaratia at that time that they were joined moved around together then split up then rejoined to make Nuna (this is amazing). geodynamics.curtin.edu.au/research/research-highlights/supercontinent-nuna-formed-two-stages/ A guy/lady below said that Nth Qld bits were also joined to America in NUna's time and I searched and found he/she was correct. geodynamics.curtin.edu.au/research/research-highlights/supercontinent-nuna-formed-two-stages/ If you root around you will find that maps of Nuna have bits of Australia up against Lauratia (America) during that time along with Antartica. Plus this shows that as well as the zircon shown in the ABC article that paleaomagnetic evidence supports the zircon data. Even more cool. ie it shows where the land was relative to the magnetic poles over time and thus how the land wanders and where it was at any time. So it does look like Tassi in Nuna's time was not there until a basin formed between the LAuratia and Antartica and sediment poured into them from each forming the rocks that make those we see in the ABC movie, ie sedimentray deep sea rocks (turbidites, there are some beauties on the west Wales coast and Devons coast, at Nundal near Tamworth in NSW and in the Vicotrian Alps north of Sale. There would be laods more eg around jenolan Caves west of Sydeny but have seen all these but they are all way younger than the Tassie ones, sayeg 400 mya). So thanks Oceangraphics due to your cast I have explored and learnt heaps. You may want to add the detail about the recent land bridge between Tassi and Victoria as I explained above. What I'd like to know is if Tassi is where it is and the Australian eastern coastline was west of Tassi's present position right up till say the Silurian (I am playing with ideas here and soome facts might not be quite spot on eg ages of where the eastern coastline was in detail at times) was west of Tassi's preent position. So where was Tassi then, one its own to the south and east of most of Australia (Australia acrrted from west to east from about and about a third has been added steadily eastwards since the cambrian about 500mya. This was my career, so people do not feel like you are stupid for not knowing this or being able to mucj around with ideas like this. What you are seeing here is how geologists work things out. It takes work. But it is lots of fun.
Very interesting. At one point, part of Australia was indeed attached to North America. If I'm not mistaken, North American rock has also been found in the northern tip of Queensland. It's really cool to see how far rocks have traveled.
The rocks in Joshua Tree National Park here in south central California have rocks from when it was attached to Australia. It was great to hear about Tasmania and its part in this process.
@@harrietharlow9929 It is! I use these speeds to think about the tectonics of the southern San Andreas as it merges into the Gulf of California Rift Zone (GCRZ). I drive the area frequently.
@@harrietharlow9929 Also, Have you heard:? Just as West CA, Baja is moving north, geologists are *debating* if a piece of Mexico moved up to Washington and another piece might have moved to Alaska. And the speed record for me is how India split from Africa and "raced" north into Asia(maybe 5" a year?). Check the TH-cam channels of past tectonic movements.
My cousin's husband is a jeweller and he told me that miners found a lode of some precious metal/stone [I don't recall now] in south west India...so they realized that that part of the subcontinent used to be connected to Mozambique.They figured that the lode/vein or whatever would continue over there for exploration purposes.
We do the same when looking for oil and gas, eg oil was predicted off Canada's east coast as it would have been joined to Europe where oil and gas had been found in large quanities in the North Sea, so they/we looked and found it in Canada.
Looking at a map, it would be easy to see Tasmania being connected to Australia with only a shallow body of water separating the two. It never dawned on me just how different geologically could be. Now I know... thank you.

@@johnrobinson8941 Thanks for comment. Yeah, he isn't a PhD in Geology. But he is rather accurate in many ways. I too questioned Tasmania. In some mapping programs you can see the seabed. Looks like Tasmania sit right on top of same plate.
Plate tectonics is fascinating. While this is only one of several models explaining this event, every one of them has rocks, continents and supercontinents tearing themselves apart, moving great distances and slamming into one another. Thanks for another great video Oz
As a Geologist who grew up, has lived in, studied, and works in Tasmania, well done on conveying this info in an informative yet fun way. There so much more you could talk about with the Jurassic dolerites covering 1/3 of Tasmania's surface, to the different granite intrusions on the west and east coast that all make up the mountains and landforms that tourists often flock to see, like Freycinet and Cradle Mountain. Looking forward to a part 2 haha.
Wow, I've often wondered about how Tasmania could be connected to Victoria. As you fly from Melbourne you can see just how flat the Victorian landscape is, compared to how hilly and mountainous Tasmania is. Now I know that there not from the same landmass at all and it makes so much more sense!

Should’ve mentioned that the Mt. Read volcanics forming orogen was a very complex continent-arc collision! The formation of the western half of Tasmania during the Tyennan orogeny is very, very complicated and interesting.
Amazing how far this little chunk of lad has travelled and how wild the landscape would have looked when it was still attached to North America then to Antarctica.
Good luck saving up for your rock crusher. I just saved up and purchased a Mini Rock crusher that works with an angle grinder. Only to discover it is not mini enough to work with an affordable battery powered angle grinder. So I am back to making the 4 hour hike with a backpack full of ore and crushing in my shed. There’s not enough gold to pay for the petrol but it is so much fun and it is keeping this old fella fit. Northern NSW.
Keen to watch this.. I heard that rocks on the coast of Tassie match up with parts of North America?!?! Forgive me if my memory is off 😬 .. what’s cool about that to me is that there were native indigenous populations in Tasmania before colonisation.. I wonder if they came from there and spread to mainland Australia, or other way around, or perhaps had unique genetics altogether - I’m sure answers exist to already.. I’m just not across it.. very cool nonetheless
@@einfelder8262 NOoooooooooooo!!!! Put a pin on this video - like when Spicks and Specks pointed out that the Men at Work song had that old scout song theme in it :(
You explained it beautifully 👌. When I was at the Grand Canyon a few years ago, I had already known we were part of there once, and I thought how amazing the earth is 😳❤
Hello from Tasmania nice know my home state Tasmania was part of North America well over a billion years ago. As an a Tasmanian any chance of me getting dual citizenship of America LOL.
There was a program on ABC a couple of years ago that found rocks on Frenchman's Cap (mountain range in Northwest Tasmania), which are the same as some rocks in China
Very interesting video, we love travelling our home island and finding new and fantastic looking geology. Thanks for the very informative video Oz, cheers mate
I went to Tasmania once... back in 2004. It's been twenty years now, but I still remember broaching this topic with one of the locals there... Neither of us were very well versed on the subject, but when I suggested that Tasmania was not originally connected to the Australian mainland, I distinctly remember the lady I was talking with nodding both of her heads in agreement. LOADING REPLIES
Actually the doco I watched was from the abc and spoke more about the geology from Canada that matches Tassie geology which does not match mainland Aus...
We say. You can tell a mainlander; but you can't tell them much... Interesting how slowly they drive... How close to crests and curves they park... Slightly ignorant, perhaps... ...
Apparently when the bass straight was formed the school shark changed into the gummy shark because it's diet was changed from mainly fish to crustaceans
From watching Nick Zentner I know Australia or at least parts of it were once connected to North America. Also from what I have learned, Alaska didn't exist until sometime in the last 100 million years give or take.
Nick Zentner rules! I remember seeing that in one of his videos in the "Nick From Home" series. If you haven't already done so, may I suggest that you check out his "Eocene A to Z" series?
@@Eric_Hutton.1980 Cool! I would love to be be able to audit some of his classes. Luckily I have tons of Nick Zentner videos. When you see him, please give him my best. He really is a very cool guy.
Interesting. As you said, there's a bit of speculation as to where it was so long ago. Some 5 years ago I heard it was jammed between Scotland and the New England/Nova Scotia part of the US, before that area was split by plate separation. This was based on similar rock types I think. I see it's just as likely/unlikely to be further south down a spinning portion of the North American land mass.
That's interesting as some whorled agates I find in Tasmania are nearly identical to some Scottish whorled agates I've seen from the Isle of Mull and I haven't seen examples anywhere else.
NOw that is interesting, I am from the UK did my geology degree at Sheffield Uni there and then got a job looking for oil and gas in 81 in Oz (much of the time between Tassie and Victoria) and never left Oz. I knew Scotland was part of the North American continent and that did make me wonder re Tassie as it looks from this to be in the position where Scotland would have been. But I am wondering where Europe and Asia fit into the information presented here and to sort out this quandrie we need to know where it is as Scotland moved off to join Europe. So maybe Tassie was between Scotland and America like shown here but, if so then how does Europe get into the picture with Antartica in the way. Hmmmmmm!!!
@@briancrowther3272 Yeah, I was born in Glasgow and my parents emigrated over here when I was three months old. I agree, such a mystery how Tassie is this tiny chunk of land completely foreign to the rest of Oz, and travelling such a long way to sidle up beside it. Almost like it had its very own continental plate to scoot around on.
If you took the water out of the oceans aren't all continents connected by land? The continents aren't floating around and if the continents changed over time wouldn't it be the sea levels or the continental shoulders breaking and falling away? Something to consider anyway
So, tell me. When Captain Cook navigated Australia and named it New Holland, Tasmania was joined to Australia. Oh well, that's what history taught me......
Hey mate, our little island is very symbolic. It actually separated from the mainland as Gods symbolism of having our second head removed. But on a serious note, we are actually one of the first places in the world to go carbon neutral so that's an achievement I guess.
Nice narative but I would rather prefere an animation of those Land masses moving on the acreen ... and naration in tune with picture. It is very hard to follow what you are saying and simultaneously watch some drone futage ... Waiting to crush into the scenary. I am kidding... but yep... All the best.
Just an FYI: inanimate objects don't live such as stars, continents and microcontinents. Would have liked to have seen more maps over the course of hundreds of millions of years. Still, good video.
@@Aaron_Hanson No, it's a mass of decaying coral. You can think of it like a building, there are living people in the building.

How to make a paradise: be at the top of the world for a while, drift for a few million or billion years, do nothing for a few million or billion more, drift south for a few million / billion more until you bump into a bigger landmass, remain isolated mostly , apart from a land bridge every now and then, and hey presto,, you’ve reached paradise!

@@johnrobinson8941 Thanks for comment. I was taught the same, both from same source.
@@SJR_Media_Group the man is not a Geologist he has said so many things on here which are simply made up and he is getting away with it, Tasmania is part of the continent just put the question into Google, it clearly shows it is part of the mainland and so is Papua New Guinea
@@johnrobinson8941 Thanks for comment. Yeah, he isn't a PhD in Geology. But he is rather accurate in many ways. I too questioned Tasmania. In some mapping programs you can see the seabed. Looks like Tasmania sit right on top of same plate.
How cool is that??? I guess that makes us Yanks and Tazmanians family! HA! Just one more place I need to visit now, thanks Oz!
Thanks Tassie!! 🤘
Some really neat rocks there. Ultra mafic rocks to with strange plant communities.
Mainlander saying nice things about tassie. Thumbs up
Great video about where I live. The people are different, mostly in a good way :)
Yes they are!
yeah were special.
Wow!! So interesting. Thanks Oz Geo 👏👏👏
Glad you enjoyed it!
Well presented your doing an awesome job with your channel and have a good selection of topical varying , keep up the good work 👍
Thank you very much!
@@OzGeologyOfficial your welcome👍🇭🇲
Plate tectonics is fascinating. While this is only one of several models explaining this event, every one of them has rocks, continents and supercontinents tearing themselves apart, moving great distances and slamming into one another.
Thanks for another great video Oz
Well said! Thanks for watching!
@@Scifi_Ape that's because very few 'scientific people' refuse to use evidence to reach conclusions.
wow that was relay interesting....
thanks ...!
You're welcome!
Great video
Glad you enjoyed it!
Thanks for posting. Very interesting as usual. Great work keep it up.
Thanks for watching!
I’m blown away by the way you can make me understand the most complicated of topics understood 😂
Great content mate, cheers 🍻🇦🇺
Thanks! 😃That's a huge compliment! I really do appreciate that!
@@OzGeologyOfficial “huge compliment?” That’s an understatement 😂
I’m so dense I make blue gum seem malleable 🤦♂️
As a Geologist who grew up, has lived in, studied, and works in Tasmania, well done on conveying this info in an informative yet fun way. There so much more you could talk about with the Jurassic dolerites covering 1/3 of Tasmania's surface, to the different granite intrusions on the west and east coast that all make up the mountains and landforms that tourists often flock to see, like Freycinet and Cradle Mountain. Looking forward to a part 2 haha.
shut up nerd.
someone had to say it 😜😜
Surely they’re basalts if there found at surface?
Fascinating! Thank you
Glad you enjoyed it!
Great video mate 👍
Glad you enjoyed it mate! Thank you!
Wow, I've often wondered about how Tasmania could be connected to Victoria. As you fly from Melbourne you can see just how flat the Victorian landscape is, compared to how hilly and mountainous Tasmania is. Now I know that there not from the same landmass at all and it makes so much more sense!
Everything this mans says is wrong! Tasmania never collided with mainland Australia! Tasmania is part of mainland Australia, it always has been, New Guinea is also part of the continent, what he has said is simply made up!

@@johnrobinson8941 oh damn really? This is the first video I've seen by him. I guess I have no idea who he is and if he's right or not.
Very good. Thanks.
Micro Continent Tassie- I love it!
Should’ve mentioned that the Mt. Read volcanics forming orogen was a very complex continent-arc collision! The formation of the western half of Tasmania during the Tyennan orogeny is very, very complicated and interesting.
Do volcanoes and/or their processes cause rare elements to congregate in their outcomes due to density within magma essentially?
yes alot of volcanic plug on the east coast that produce zircons sapphires and topaz
Amazing how far this little chunk of lad has travelled and how wild the landscape would have looked when it was still attached to North America then to Antarctica.
Intro got me laughing pretty hard. Gonna have to send this to my Tazie friends since they'll get a kick out of the "strange in other ways" comment.
Good luck saving up for your rock crusher. I just saved up and purchased a Mini Rock crusher that works with an angle grinder. Only to discover it is not mini enough to work with an affordable battery powered angle grinder. So I am back to making the 4 hour hike with a backpack full of ore and crushing in my shed. There’s not enough gold to pay for the petrol but it is so much fun and it is keeping this old fella fit. Northern NSW.
Such a beautiful place that everyone should try to visit
This is so cool. Tasmania ❤
Great video mate if you'd like some Tasmanian stones for your videos feel free to get in contact
Excellent, learned a lot more about Tas, than the knowledge l gained in 1st year geology back in '95.😊
Glad you enjoyed it!
Tasmania and Arizona USA. i would of *never* guessed that connection.
Great video and I had no idea of this.
I've always LOVED the map of Tasmania!😜😜
What can I say. I was looking forward to this video and it didn't disappoint. Five stars.
Keen to watch this.. I heard that rocks on the coast of Tassie match up with parts of North America?!?! Forgive me if my memory is off 😬 .. what’s cool about that to me is that there were native indigenous populations in Tasmania before colonisation.. I wonder if they came from there and spread to mainland Australia, or other way around, or perhaps had unique genetics altogether - I’m sure answers exist to already.. I’m just not across it.. very cool nonetheless
Watched the video.. I reakon I wouldn’t even score half points at the local bowls club trivia!! 😂
Great video thank you although I must say the music sounds like the score to a tim and eric infomercial
mind blown...it really is a mini continent
"Some scientists consider Tasmania as a micro-continent in its own right." OMG don't let them know that :( - Great video!
Too late - I'm one of them and now I know things......😀
@@einfelder8262 NOoooooooooooo!!!! Put a pin on this video - like when Spicks and Specks pointed out that the Men at Work song had that old scout song theme in it :(
Ha ha too late . 😜.
You explained it beautifully 👌. When I was at the Grand Canyon a few years ago, I had already known we were part of there once, and I thought how amazing the earth is 😳❤
Hello from Tasmania nice know my home state Tasmania was part of North America well over a billion years ago. As an a Tasmanian any chance of me getting dual citizenship of America LOL.
@@peterlyall2848 Expanding Earth explains it much better that this.
Very interesting,,,,,
There was a program on ABC a couple of years ago that found rocks on Frenchman's Cap (mountain range in Northwest Tasmania), which are the same as some rocks in China
Very interesting video, we love travelling our home island and finding new and fantastic looking geology. Thanks for the very informative video Oz, cheers mate
Glad you enjoyed it! Thanks mate!
I went to Tasmania once... back in 2004.
It's been twenty years now, but I still remember broaching this topic with one of the locals there...
Neither of us were very well versed on the subject, but when I suggested that Tasmania was not originally connected to the Australian mainland, I distinctly remember the lady I was talking with nodding both of her heads in agreement.
LOADING REPLIES
Interesting theory. What is your source?
Nice video! I think the music is a tiny little bit too loud.
The best place on the planet. 🌏
Yes, I’ve watched this doco before and it is a mini supercontinent and I am at home 🤟
Actually the doco I watched was from the abc and spoke more about the geology from Canada that matches Tassie geology which does not match mainland Aus...
Great!
So... Tasmania is adopted.... Makes a lot of sense.
Thankyou, this was amazing. Wonder where all will be in the next 40+ million years.
wow, ty
My pleasure!
After meeting several Tasmanians, this explains a lot.
We say. You can tell a mainlander;
but you can't tell them much...
Interesting how slowly they drive...
How close to crests and curves they park...
Slightly ignorant, perhaps...
...
@@alwilliams8882 touche
just about to watch this but i mine and cut sapphires and on the east coast of Tasmania
Apparently when the bass straight was formed the school shark changed into the gummy shark because it's diet was changed from mainly fish to crustaceans
From watching Nick Zentner I know Australia or at least parts of it were once connected to North America. Also from what I have learned, Alaska didn't exist until sometime in the last 100 million years give or take.
Nick Zentner rules! I remember seeing that in one of his videos in the "Nick From Home" series. If you haven't already done so, may I suggest that you check out his "Eocene A to Z" series?
@@harrietharlow9929 I've been there from the start. Nick in his backyard. Bijou the cat, Muffler boy and the three frogs on the wall.
@@Eric_Hutton.1980 Cool! I would love to be be able to audit some of his classes. Luckily I have tons of Nick Zentner videos. When you see him, please give him my best. He really is a very cool guy.
Cool
Our state is pretty awesome
We are special and I wouldn't change a thing about us or this state (especially the food we have).
As a Tasmanian I often feel more kinship with the Kiwis than I do for the mainland Australians. Maybe it's an island consciousness more than geology.
Interesting. As you said, there's a bit of speculation as to where it was so long ago.
Some 5 years ago I heard it was jammed between Scotland and the New England/Nova Scotia part of the US, before that area was split by plate separation. This was based on similar rock types I think.
I see it's just as likely/unlikely to be further south down a spinning portion of the North American land mass.
That's interesting as some whorled agates I find in Tasmania are nearly identical to some Scottish whorled agates I've seen from the Isle of Mull and I haven't seen examples anywhere else.
NOw that is interesting, I am from the UK did my geology degree at Sheffield Uni there and then got a job looking for oil and gas in 81 in Oz (much of the time between Tassie and Victoria) and never left Oz.
I knew Scotland was part of the North American continent and that did make me wonder re Tassie as it looks from this to be in the position where Scotland would have been. But I am wondering where Europe and Asia fit into the information presented here and to sort out this quandrie we need to know where it is as Scotland moved off to join Europe. So maybe Tassie was between Scotland and America like shown here but, if so then how does Europe get into the picture with Antartica in the way. Hmmmmmm!!!
@@briancrowther3272
Yeah, I was born in Glasgow and my parents emigrated over here when I was three months old.
I agree, such a mystery how Tassie is this tiny chunk of land completely foreign to the rest of Oz, and travelling such a long way to sidle up beside it. Almost like it had its very own continental plate to scoot around on.
I live in Tasmania it’s beautiful
If you took the water out of the oceans aren't all continents connected by land? The continents aren't floating around and if the continents changed over time wouldn't it be the sea levels or the continental shoulders breaking and falling away? Something to consider anyway
I would suggest Tasmania was joined to mainland Australia, mainland Australia is moving north with a slight clockwise turn, tazmania was left behind .
So, tell me. When Captain Cook navigated Australia and named it New Holland, Tasmania was joined to Australia. Oh well, that's what history taught me......
Hey mate, our little island is very symbolic. It actually separated from the mainland as Gods symbolism of having our second head removed.
But on a serious note, we are actually one of the first places in the world to go carbon neutral so that's an achievement I guess.
Not so comforting, however, to realise humanity is the carbon they intend to neutralize.
Maybe be thankful for hydro electricity...
I'm from here
Its cold ❄❄❄
This is my idea of a short video. Always a pleasure watching these ones.
Music is very distracting, and volume is too high.
I still want to see someone Interpret tectonic plate movement over the millennia, on the possible way the planet looked , using 3d Graphics
I visited Tas some 10 years ago. A magical place -- but not all the magic was the good kind.
Dark MOFO ?
it feels like if you put tasmania part of north america you wouldnt see the differents.
You were there to see this?
Nice narative but
I would rather prefere an animation of those
Land masses moving on the acreen ... and naration in tune with picture.
It is very hard to follow what you are saying and simultaneously watch some drone futage ...
Waiting to crush into the scenary.
I am kidding... but yep...
All the best.
But we're still moving, or at least mainland Australia is: 7cm north every year.
its a vast SCALE of time..(scale,music reference lol)
So Arizona and Tasmania are cousins
I beg to differ. My understand is that New Zealand, Tasmania, Australia and New Guinea were all connected.??
Nope, Tasmania was its own boss till 500 million years ago :)
Expanding Earth makes a gazillion more sense than that tectonic plates basically floating around acting like bumper cars.
It really, really doesn't.
@@OzGeologyOfficial Yes, it really does.
Just an FYI: inanimate objects don't live such as stars, continents and microcontinents. Would have liked to have seen more maps over the course of hundreds of millions of years. Still, good video.
I'm aware of that. But mapping something this old is quite difficult so that's why I stuck to my garbo paint "art" instead hahaha.
our Sun is a star and its life will end one day, it lives. also, continents and microcontinents have lives.
So the Great Barrier Reef isn’t a living organism?
@@OzGeologyOfficial Fair enough. There are some videos that give a good sense: th-cam.com/video/OGdPqpzYD4o/w-d-xo.html
@@Aaron_Hanson No, it's a mass of decaying coral. You can think of it like a building, there are living people in the building. The materials the building is made out of might contain material from creatures that used to be alive. Obviously in a reef there are creatures that are stationary unlike humans. Language when used correctly is used like math and if it is not used logically then things don't add up.
Thanks Tassie for lifting the land that would become Melbourne, you guys are just awesome.
Never knew that. And I'm a 51 y.o. aussie
Love u 2
I’ve known this for years and I have told people that .not everyone believed me
Basically part of Victoria anyway so we own it.
Tasmania and Arizona were as closely connected as Tasmanian siblings/couples.
We who live in Tasmania do not see ourselves as part of that other island "Australia".
How to make a paradise: be at the top of the world for a while, drift for a few million or billion years, do nothing for a few million or billion more, drift south for a few million / billion more until you bump into a bigger landmass, remain isolated mostly , apart from a land bridge every now and then, and hey presto,, you’ve reached paradise! Otherwise known as Tasmania.
Please replace ‘billion’ or ‘ million ‘ where you see fit . Yes I live in Tasmania, but not born here, a Tasmanian by choice, can you believe it? 😁.
Yes, I can believe it. My cousin and her husband have retired to Tasmania to live on some acres after years of inner city living in Melbourne.
@@markfryer9880 oh really 😍. That’s lovely. It’s magical here , a world away from everything. I hope they are enjoying it. I’ve come a little further my friend. From Ireland, I’ve been here twenty three years.
Yup! Agree with Mark, I love Tasmania and have considered living there many times hahaha!
@@lilliankeane5731 Your a Tasmanian Skippy now after 23 years in Australia! I'm not 100 per cent sure on where in Tasmanian they are. I think that it's one of those English style heritage towns.
@@markfryer9880 😆😆😆. Yes .. a Tasmania devil. There’s some lovely ye olde towns here. ‘Ross’ is one of my favourites to visit.
Please note; this is all a theory.
New Guinea has been connected to Australia longer than Tasmania.
It’s all speculation at the end off the day but interesting anyway 👍🍻
Not true. The only real speculation is the positioning during Nuna. The rocks, however, don't lie.
Tasmania was joined to South Australia.
So Victoria owes Tas for mining royalties?
No Tassie owes us for rear ending us in the collision. No wonder my neck hurts!
@@markfryer9880 yeah I put my neck out in '92 but I think that was a bit further back 👍
Victoria owes Tasmania for the founding of Melbourne.
All in favour of kicking Tasmania out of Australia? I agree completely.
