The impressions are like injection molding/ compressed into the debris, so we are left with distinct amazing shapes in every cave. And pebbles and inclusions on the roof, and inner surfaces. It's abundantly clear that this sediment with its foot prints if dinosaurs which were running for their lives- similar to the giant mass dinosaur burials sites in the US, was from the global flood.

Never understood what the mean by the age of a rock. Ok for sedimentary rocks it must be the age when the particles came together, but aren’t they measuring the age of those particles here, not the formation? Wouldn’t everything be the “age” of the coalescing earth? What about igneous rocks? Is the age of a newly formed rock shelf on the Big Island considered to be 4 weeks if the lava flow was last month? What about the individual particles within that newly formed rock? What starts the clock?
It’s practically impossible to accurately date rocks without massive assumptions, especially over any period of time. They can only assume. It’s something often overlooked. It’s true that scientists are expected to know how old things are but they rarely do for long time spans. Dinosaurs with DNA found in them are supposed to be 100+ million years old, yet the half life of DNA is 500 years…
There is a starting point. The solar system in which we reside went through the "Late Heavy Bombardment" about 3.9 billion years ago when Earth's surface became molten (Hadean era), when the Earth cooled enough to solidify s rocks would be a good starting point.
Excellent. Great views of a beautiful location and well-written script. I love watching the rock hammer opening up a window on the past. I would have added that when zircon crystallizes, it excludes lead, so it starts off a lead-free.
Look at the thickness of the individual layers at around 5:55 on this video. These are individual annual depositional Layers. Notice that there are thousands of these layers, and they are around 1 cm thick.
There is no way on earth anybody can look at lichen covered outcrops, without knowing anything about sedimentology, petrology and stratigraphy of the area and be able to determine the sedimentation rate. They could be one year, one day or a thousand years. Just trust the geologists that actually work there.

And much of it will be below sea level. That is NOT just because of sea levels rising from the melting ice either. The mass of the ice currently on top of Antarctica is pressing it downwards. This land will not spring back (isostatic rebound) until much longer after the ice melts. This is what may have happened in SE US where the Grand Canyon is. The mass of ice pushed the land downwards. The river was already flowing in the direction it currently is. As the ice melted, the land rose and the river cut its channel.
@@rickkwitkoski1976 much like what’s happen with Canada and Europe right now Antarctica will over time move up. Because all that pressure has been released and they can finally unsquish themselves.
Sedimentation has alternating lighter colored layers ( summer ), and darker colored ( winter ) layers. The micro organisms eat the summer layers when it is warm enough to be active, and reproduce a lot. In the winter it is too cold, so the darker sediments settle to the ocean floor without being eaten by the micro organisms. Generally, the summer layers are thicker, and the winter layers are thinner. ALSO: The Rocks from the Colorado River in the US were deposited on the slopes of the Mountains in New Zealand, when they were joined, and before the Pacific Plate Moved a thin strip of Mexico North and cut off the material access to New Zealand. Then the two continents ( Zealandia ), and North America drifted apart. ( Way apart ). Zealandia is mostly submerged and is about 1/3 rd the surface area of Australia.

1:37 How can 'Nuna' be called a 'Super Continent' when all the pieces aren't joined up? Here we just have a number of continents, not a super continent like Pangea.
Continents are distinguished based on crust type and plate elevation, rather than if the piece of crust is above water. This is analagous to Sahul; yes, the sea separates PNG from Australia, but continental crust still joins PNG to Australia. Subtract only a few tens of metres of sea level, not kilometres, and dry land would connect Australia to PNG.

@@columnarbasalt4677 In fact, the world's oldest known zircon, and thus rock remnants, is in Western Australia. The oldest still remnant rocks are either in Canada's Northwest Territories or Greenland (they both fall within each other's radio-carbon dating "plus-minus" overlap, so we don't know which is oldest).
1750 Ma is close. In Colorado, USA, there is a batch of rocks that is between 1780 Ma, and 1700 Ma, with a median of 1740 Ma. 1740 - 66 ( Last extinction event ) = 1674. 1674 / 9 = 186.0 ( See: A Correlated History of the Earth from the Black Hills Institute ), a wall chart. Their cyclicity of extinction Events is based on 186.0 Million years per cycle. 66, 252, 438, 624, 810, 996, 1182, 1368, 1554, 1740, and on back to 4530. I did another one based on 186.6 million years per cycle. 66, 252.6, 439.2, 625,4, 812.4, 999.0 , 1185.6, 1372.2, 1558.6, 1745.4, and on back to 4544.4 Ma. This is based on the recession rate of the Moon away from the Earth, ( 2 X 4544.4 = 9.0888 E 9 ). The Earth Grows faster than the Moon, and its increasing gravity accelerates the Moon to a Higher Velocity, and a greater orbital distance from the Earth. It is a small amount, around 1 mm of increasing radius of the Earth per year, which is about 10^15 kg per year increase in Earth's mass each year. A small amount of increase over a vast time period made the Earth what it is today, 6,371,008,000 mm Radius. 1780 Ma, to 1700 Ma was one of those fast growing time periods. Centimeters per Year, not millimeters per year.

India and Australia are actually on the exact same continental plate. Where one drifts, the other always follows. If the plate breaks, the current unsubmerged continental crust making up India and Australia might collide one day. In the VERY very distant future. Short of the crust breaking though, it's unlikely they will meet up. Crust can bend and flex, but I don't know of any situations where it bent to the point of erasing the current equivalent of the Indian Ocean (which, interestingly, is continental/felsic rather than oceanic/mafic) and allowing the tips to merge or collide. Though, who knows? Maybe it used to happen all the time, we just don't have the probable evidence that it does happen, yet, cause it has not happened in a few billion years.
Sounds to me like there a ton of guess work in trying to figure out the age of rocks and even more guess work in trying to figure out what the earth looked like just going back 500 mill years ago

Regarding radioactive dating of Uranuim in the crystals, is there an assumption that all of the Uranium in the entire world has a common origin and common age?
It doesn't matter how old the uranium is or where exactly it came from - it always decays at the same rate, and zircons don't contain any lead when they form because it doesn't fit properly in the crystalline structure. And by decaying at the same rate I mean any given uranium atom has a tiny but fixed % chance of decaying at any given moment, whether it's 10 billion years old or just formed yesterday.
@@brucetucker4847 So all Uranium is at the same stage of decay at some starting point in the past? Or is all Uranium in the world at the same stage of decay at any point in time and it’s the quantity present that makes a difference? Is it the ration of Uranium to Lead that is measured so absolute quantity doesn’t matter? How does this work?
@@jeffbransky7966 It's the ratio of lead to uranium. How the dating works is this: when zircon crystals form they can contain uranium but they cannot contain lead. But when a uranium atom inside a zircon decays to lead, the lead atom still remains locked inside. Therefore any lead found in zircons must be uranium atoms that underwent radioactive decay at some point since the zircon crystal formed. Uranium-238 has a half-life of about 4.5 billion years, meaning that if you have a gram of it today in 4.5 billion years half of it will have decayed to lead. So if you crack open a bunch of zircons and find that the ratio of uranium to lead is 1:1, the zircon must have formed about 4.5 billion years ago. How much of that deposit of uranium had already decayed to lead when the zircon formed doesn't matter, because any lead in the molten rock won't be incorporated into the zircon's crystalline lattice. That's why they're using the microscope to isolate individual zircon crystals from the surrounding rock, because the surrounding rock could contain other lead or uranium that would skew the ratio. (This is a simplified description, for instance, there's more than one naturally occurring isotope of uranium and they have different decay rates, but hopefully it's close enough for you to understand the principle.)
How could this be case if it was once exposed to the mainland around 10-12,000 years ago? and technically still is connected underwater. Go look at any 3d map that separates shallow from deeper oceans and you can clearly tell.
Deposition and volcanoes. Just like the very ancient parts of north America are in the middle of Canada. Also, plates can have both oceanic and continental crust.
@@vedangsinghal4754 I think you can partially tell through extinct volcanoes, but both Tasmania, as well as the mainland also had them millions of years ago. Even it was from somewhere else; I'd say it was probably still part of Australia's mainland, imo. Also given the fact the continental crust is virtually the same throughout most of the country, except for central Australia, which seems more realistic. The geologists in this vid are mainly talking about coastal areas where some rocks look somewhat distinct from other parts of the world which could maybe tell a different story but it's still not evident.
Darrell, the position of Tasmania in relation to Australia would be virtually identical 10,000 years ago. On a plate tectonic time scale, that was yesterday.
Nuna... another new name! And when did Gondolwana become a supercontinent? It was one of the overcontinents that came from Pangaea, was not it? Every video speaking of older supercontinents uses a different name!
HAHAHAAHAHA- but they told us that ages ago, tassie was connected to australia with a land bridge cause they sea was low, so thats not what happened, or is?
@@columnarbasalt4677 I'd say it's more likely that it was once exposed to the mainland. Look at any 3d map where the shallow water is divided by the deeper ocean and you'll see that it's still connected underwater. And this definitely seems more realistic than coming from somewhere on the other side of the world. Even if that was the case though; it was probably still part of the mainland.
A land bridge is just anywhere below the water which is shallow enough to be exposed when the water level drops. There are mountains and plains and valleys underwater the same as there are on land, it's not like land just floats around in a massive swimming pool. You can see how this works for yourself by putting a bunch of rocks of different sizes into a large bowl, then slowly pouring water in and seeing how the surface exposed land area changes shape.
@@spitcloth I seen diagrams, drawings, articles.. proper schooling back in the day lol, "proving" it back then, Now more "proof" now that it isn't Its quite amusing
That is also very much true. But that last happened only several tens of thousands of years ago. Yes that's a very long time ago; but it's much much much more recently than they're talking about here. By 10,000 years ago the continents were already basically where they are now, but since the ocean levels were lower, several land bridges existed. Most famously the land bridge between Asia and North America, which existed at the same time. In no way does a land bridge between Tasmania and Australia indicate that they are part of the same original continental formation, any more than the Bering land bridge indicates that Asia and North America are. Similarly, India is crashed into Asia right now; but it is a different continental plate.

What about the individual particles within that newly formed rock? What starts the clock?
When it hardens and it's chemical composition is set relative to that of the outside world.
It’s practically impossible to accurately date rocks without massive assumptions, especially over any period of time. They can only assume. It’s something often overlooked. It’s true that scientists are expected to know how old things are but they rarely do for long time spans. Dinosaurs with DNA found in them are supposed to be 100+ million years old, yet the half life of DNA is 500 years…
There is a starting point. The solar system in which we reside went through the "Late Heavy Bombardment" about 3.9 billion years ago when Earth's surface became molten (Hadean era), when the Earth cooled enough to solidify s rocks would be a good starting point.
Very interesting and informative presentation! Thank you!!! 😊
Excellent. Great views of a beautiful location and well-written script. I love watching the rock hammer opening up a window on the past. I would have added that when zircon crystallizes, it excludes lead, so it starts off a lead-free.
Thankyou for teaching me that! Iron pyrite doesn't leak lead fuel haha
Look at the thickness of the individual layers at around 5:55 on this video. These are individual annual depositional Layers. Notice that there are thousands of these layers, and they are around 1 cm thick.
There is no way on earth anybody can look at lichen covered outcrops, without knowing anything about sedimentology, petrology and stratigraphy of the area and be able to determine the sedimentation rate. They could be one year, one day or a thousand years. Just trust the geologists that actually work there.

I wish I could see Antarctica once the snow and ice melts. I bet it's amazing.
And much of it will be below sea level. That is NOT just because of sea levels rising from the melting ice either. The mass of the ice currently on top of Antarctica is pressing it downwards. This land will not spring back (isostatic rebound) until much longer after the ice melts.
This is what may have happened in SE US where the Grand Canyon is. The mass of ice pushed the land downwards. The river was already flowing in the direction it currently is. As the ice melted, the land rose and the river cut its channel.
Haaaaaa good one, clever. Thumbs up.
@@rickkwitkoski1976 much like what’s happen with Canada and Europe right now Antarctica will over time move up. Because all that pressure has been released and they can finally unsquish themselves.
The Tasmanian movie called the Nightingale was surprisingly really good. That movie is disturbing and really controversial around the world.
I saw this when ABC first broadcast it & have come back for another look, as it is just such an amazing story.
Tasmania truly built different
Coming from Québec city, those rocks look the same as some on Orléans Island just nearby!
Sedimentation has alternating lighter colored layers ( summer ), and darker colored ( winter ) layers. The micro organisms eat the summer layers when it is warm enough to be active, and reproduce a lot. In the winter it is too cold, so the darker sediments settle to the ocean floor without being eaten by the micro organisms. Generally, the summer layers are thicker, and the winter layers are thinner.
ALSO: The Rocks from the Colorado River in the US were deposited on the slopes of the Mountains in New Zealand, when they were joined, and before the Pacific Plate Moved a thin strip of Mexico North and cut off the material access to New Zealand. Then the two continents ( Zealandia ), and North America drifted apart. ( Way apart ). Zealandia is mostly submerged and is about 1/3 rd the surface area of Australia.

1:37 How can 'Nuna' be called a 'Super Continent' when all the pieces aren't joined up? Here we just have a number of continents, not a super continent like Pangea.
Their collective "higher educational achievement" no longer allows for common sense
Continents are distinguished based on crust type and plate elevation, rather than if the piece of crust is above water. This is analagous to Sahul; yes, the sea separates PNG from Australia, but continental crust still joins PNG to Australia. Subtract only a few tens of metres of sea level, not kilometres, and dry land would connect Australia to PNG.
@@ishmamahmed9306 And during the last Ice Age, PNG and Australia WERE connected (same with North America and Eurasia; Japan, Korea, and Kamchatka; Australia and Tasmania, etc.).
When geologists calculate erosion do they take into account geologists with hammers?
😂😂😂
They actually do. Sometimes they even take into account whether people walk barefoot or with boots. Amateur geologists, mineral and fossil collectors and normal tursits are a huge problem in some areas.
This is a neat little video, but as a former rock-climber I wonder how come the east coast of Tassie - particularly the Freycinet Peninsula - is so alike the Wilson's Prom area if we are not connected? Or should that part of the north island be seen as part of Tasmania? 😉
You've gotta love those dolomite cliffs at Cape Raoul ! Only a maniac would climb them. But they do. Domite is volcanic lava that's punched up into columns through sediment layers.

But zircon was formed before the rock was...sedimentary????
Yep! Zircon formed in igneous rocks then weather out with other minerals and rocks to form sedimentary rocks.
@@columnarbasalt4677 In fact, the world's oldest known zircon, and thus rock remnants, is in Western Australia. The oldest still remnant rocks are either in Canada's Northwest Territories or Greenland (they both fall within each other's radio-carbon dating "plus-minus" overlap, so we don't know which is oldest).
@@andyjay729 Radiocarbon dating isn't used on zircons as they contain no carbon and are way, WAY too old.
@@filonin2 I was talking about the oldest still-extant rocks, as opposed to rock remnants.
"Tassie's a little bit special. The coastlines are unique." Immediately start smashing it with hammers.
1750 Ma is close. In Colorado, USA, there is a batch of rocks that is between 1780 Ma, and 1700 Ma, with a median of 1740 Ma.
1740 - 66 ( Last extinction event ) = 1674. 1674 / 9 = 186.0 ( See: A Correlated History of the Earth from the Black Hills Institute ), a wall
chart. Their cyclicity of extinction Events is based on 186.0 Million years per cycle. 66, 252, 438, 624, 810, 996, 1182, 1368, 1554, 1740, and on back to 4530. I did another one based on 186.6 million years per cycle. 66, 252.6, 439.2, 625,4, 812.4, 999.0 , 1185.6, 1372.2, 1558.6, 1745.4, and on back to 4544.4 Ma. This is based on the recession rate of the Moon away from the Earth, ( 2 X 4544.4 = 9.0888 E 9 ). The Earth Grows faster than the Moon, and its increasing gravity accelerates the Moon to a Higher Velocity, and a greater orbital distance from the Earth. It is a small amount, around 1 mm of increasing radius of the Earth per year, which is about 10^15 kg per year increase in Earth's mass
each year. A small amount of increase over a vast time period made the Earth what it is today, 6,371,008,000 mm Radius. 1780 Ma, to 1700 Ma was one of those fast growing time periods. Centimeters per Year, not millimeters per year.

shouldnt it be "geneticist explains why Tasmania is different"?
Capaldi's Doctor Who made a tongue in cheek comment about Australia and India kind of colliding in the future... maybe he wasn't so far wrong? :)
I mean Australia is moving north 70 mm per year. So, yeah it may or might not. We’ll never live to see it anyways
He's not wrong but we're heading to Indonesia first. So quite literally, you could say that the whole of Australia is heading to Bali.
India and Australia are actually on the exact same continental plate. Where one drifts, the other always follows. If the plate breaks, the current unsubmerged continental crust making up India and Australia might collide one day. In the VERY very distant future.
Short of the crust breaking though, it's unlikely they will meet up. Crust can bend and flex, but I don't know of any situations where it bent to the point of erasing the current equivalent of the Indian Ocean (which, interestingly, is continental/felsic rather than oceanic/mafic) and allowing the tips to merge or collide. Though, who knows? Maybe it used to happen all the time, we just don't have the probable evidence that it does happen, yet, cause it has not happened in a few billion years.

@@jonathansturm4163 But are those 23,000 descendants of Aboriginal Tasmanians, or descendants of Aboriginal mainland Australians who moved to Tasmania in modern times? I thought the Aboriginal Tasmanians were completely wiped out by Europeans.

It’s just built different. It’s not like other lands.
Surely they put those rocks they laid out back.
7:18 - 7:35 "And unto Eber were born two sons; the name of the one was Peleg; for in his days was the earth divided; and his brother's name was Joktan." Genesis 10:25 The name Peleg by the way translates into "brook or little river.
Regarding radioactive dating of Uranuim in the crystals, is there an assumption that all of the Uranium in the entire world has a common origin and common age?
It doesn't matter how old the uranium is or where exactly it came from - it always decays at the same rate, and zircons don't contain any lead when they form because it doesn't fit properly in the crystalline structure. And by decaying at the same rate I mean any given uranium atom has a tiny but fixed % chance of decaying at any given moment, whether it's 10 billion years old or just formed yesterday.
@@brucetucker4847 So all Uranium is at the same stage of decay at some starting point in the past? Or is all Uranium in the world at the same stage of decay at any point in time and it’s the quantity present that makes a difference? Is it the ration of Uranium to Lead that is measured so absolute quantity doesn’t matter? How does this work?
@@jeffbransky7966 It's the ratio of lead to uranium. How the dating works is this: when zircon crystals form they can contain uranium but they cannot contain lead. But when a uranium atom inside a zircon decays to lead, the lead atom still remains locked inside. Therefore any lead found in zircons must be uranium atoms that underwent radioactive decay at some point since the zircon crystal formed. Uranium-238 has a half-life of about 4.5 billion years, meaning that if you have a gram of it today in 4.5 billion years half of it will have decayed to lead. So if you crack open a bunch of zircons and find that the ratio of uranium to lead is 1:1, the zircon must have formed about 4.5 billion years ago.
How much of that deposit of uranium had already decayed to lead when the zircon formed doesn't matter, because any lead in the molten rock won't be incorporated into the zircon's crystalline lattice. That's why they're using the microscope to isolate individual zircon crystals from the surrounding rock, because the surrounding rock could contain other lead or uranium that would skew the ratio.
(This is a simplified description, for instance, there's more than one naturally occurring isotope of uranium and they have different decay rates, but hopefully it's close enough for you to understand the principle.)
@@brucetucker4847 Thanks. Great explanation.
Superb explanation Bruce. I never got why Zircon was used for the dating - the lattice doesn’t incorporate lead! Brilliant. Many thanks 🙏
Tasmania is different because we like it that way..
Nice recommendation, 6 years a later
As a geologist I can confirm it do be like that 😩
How could this be case if it was once exposed to the mainland around 10-12,000 years ago? and technically still is connected underwater. Go look at any 3d map that separates shallow from deeper oceans and you can clearly tell.
Deposition and volcanoes. Just like the very ancient parts of north America are in the middle of Canada. Also, plates can have both oceanic and continental crust.
@@vedangsinghal4754 I think you can partially tell through extinct volcanoes, but both Tasmania, as well as the mainland also had them millions of years ago.
Even it was from somewhere else; I'd say it was probably still part of Australia's mainland, imo. Also given the fact the continental crust is virtually the same throughout most of the country, except for central Australia, which seems more realistic.
The geologists in this vid are mainly talking about coastal areas where some rocks look somewhat distinct from other parts of the world which could maybe tell a different story but it's still not evident.
@@darrellm9915 Your opinion is irrelevant as the evidence disagrees. Science.
@not today I would think that they just discussed that in this video.
You could watch the video first and then have a better question I assume.
Darrell, the position of Tasmania in relation to Australia would be virtually identical 10,000 years ago.

Joe Dirt..... bruh.
Yeah. Now we have all this new rocks, crystal and sand. Nobody appreciates the good old day when it was just dirt
One question. Why are modern scientists still working with microscopes where right is left and left is right?
I know this has nothing to do with the video but I don’t think I’ve ever skipped a Mint Mobile advertisement… even the ones I’ve seen already.
But you would think rock/continents so old would have been eventually subducted at one fault line or another.
Continental crust is more buoyant than oceanic crust so it doesn’t really get subducted. Instead it just gets smushed on the side of a continent.
Nice! But still need to be improved with subtitles

HAHAHAAHAHA- but they told us that ages ago, tassie was connected to australia with a land bridge cause they sea was low, so thats not what happened, or is?
Opinion and idea change when presented with new information and data.
@@columnarbasalt4677 I'd say it's more likely that it was once exposed to the mainland. Look at any 3d map where the shallow water is divided by the deeper ocean and you'll see that it's still connected underwater.
And this definitely seems more realistic than coming from somewhere on the other side of the world. Even if that was the case though; it was probably still part of the mainland.
A land bridge is just anywhere below the water which is shallow enough to be exposed when the water level drops. There are mountains and plains and valleys underwater the same as there are on land, it's not like land just floats around in a massive swimming pool. You can see how this works for yourself by putting a bunch of rocks of different sizes into a large bowl, then slowly pouring water in and seeing how the surface exposed land area changes shape.
@@spitcloth I seen diagrams, drawings, articles.. proper schooling back in the day lol, "proving" it back then,
Now more "proof" now that it isn't
Its quite amusing
That is also very much true. But that last happened only several tens of thousands of years ago. Yes that's a very long time ago; but it's much much much more recently than they're talking about here. By 10,000 years ago the continents were already basically where they are now, but since the ocean levels were lower, several land bridges existed. Most famously the land bridge between Asia and North America, which existed at the same time. In no way does a land bridge between Tasmania and Australia indicate that they are part of the same original continental formation, any more than the Bering land bridge indicates that Asia and North America are. Similarly, India is crashed into Asia right now; but it is a different continental plate.
Did you know that Tasmania has the exact same sediments as the Grand Canyon, which means they were connected at one point in history???
