Fossils are the remains of living things like dinosaurs, right? Not necessarily. Fossil METEORITES are totally a thing! They're rare, but when scientists find them, they help fill in the picture of Earth's ancient past.

kid's want a ragdoll Hank. where can we buy one?

Wow, SciShow. Not usual for you to use clickbait titles.
That Swedish scientist crawling around on public floors looking for meteorites is an absolute legend. True dedication to the craft
Truly reminds me of my passionate (but mad) professors at university- take a geologist anywhere and they will find a rock to look at 😂
@@SadieAbby I'm a minor plant fanatic/amateur and still learning botanist as well as a rock hound so take me anywhere and I'll be taking pictures of plants and filling my pockets with rocks. As I learn more about plants I pay more and more attention to them and in a few years time I'll probably be catcalling plants like Crime Pays but Botany Doesn't.
Iunno, I feel like either he forgot where that one singular meteorite he found was... Or there was none in the first place
@@SadieAbby I m just imagining your proffesor on all four crawling in a floor mumbling continually to himself “rock rock rock”
the chances of finding a fossil meteorite are alot higher than you might think
but chances are, you wont know it was any different from the rock sitting next to it
That’s what makes the chances low…? Lol
The chances of finding it is high, but the chances of knowing you found it is low
Was this originally about psychopaths or something? But then psycho is swapped for meteorite
@@dillonlamb2011 we psycho meteorite hunters prefer the term geologically ambiguous
"Rock-shaped rocks are evidence of space fossils!"
[Conspiracy Nuts have entered the chat]
A rock can be shaped like anything. Why would it just be shaped like a rock unless it was trying to hide something?
@@jameshill2450 And what's the shape of a rock that's not shaped like a rock?
@@KaiHenningsena stone?
This video really inspired me. From now on, I too will spend my free time crawling around in public buildings.
Hank, your presentation style, and sense of humor make learning about these fascinating subjects that much more enjoyable! I'm a dedicated fan.
That is just plain cool, Hank! That's what I Iove about sciences like paleontology and geology--always something new coming up. Great video!
There's a theory that the Late Ordovician extinction that wiped out 70% of invertebrates was caused by a Gamma Ray Burst less than 65 light years from earth. Supposedly, it was so powerful and relatively close that it destroyed a lot of the ozone layer, and the surface of the earth was exposed to high levels of UV radiation, which subsequently helped lead to an ice age. Scientists found evidence for radiation damage in algae, and organisms that lived in shallower parts of the oceans were affected greater than ones in the deep. Pretty cool stuff.
Hank, as a German I just have to like the video for how well you pronounced "Widmannstätten"
That's what I was thinking too
You are the bestest. I love your humor and you make all the videos , fun and entertaining ,as well as teaching us to love nature.we need you . Never leave
I have a whole ass degree in Geosciences but this video taught me something completely new to me, thank you Hank!
I love that I first saw Hank in a biology class and I'm still learning from him a decade later 💛
Hank's best German pronunciation ever at 2:10!
My three fave things: space, rocks, and fossils!
Who knew they could be combined into one?
I definitely thought this was going to be a video about the ALH 84001 meteorite (the controversial magnetotactic bacteria containing meteorite). Personal opinion: just geologic magnetite! 😅
extra points for pronouncing the probably german name Widmanstätten perfectly
Rock-shaped rock has a similar ring to pie-flavored pie.
*PIE FLAVOUR*
@@VeryRGOTI *guitar riffs*
A group of people once saw a man crawling on the floor before jumping in joy and freaking out, they probably never knew what had actually happened
I am for sure going to take up that brilliant offer, but will have too when I get home tonight.
love what you do guys
Has SciShow ever done a video on the Chicxulub seiche waves? Basically when the impact struck it was so powerful that all the way from the Yucatán it shook North Dakota. Like slamming a door so hard it makes waves in a bathtub. Except with glass rain.
I love these videos so so much. Thank you for making them, I have seen almost every single scishow and they keep me so consistently fascinated and enamored with our universe. Great work team!
Damn, had no idea my country had the location with the most meteorite fossils. Great.
You can tell how excited Hank was to say “Widmanstätten”
"Cooling iron exceptionally slowly in the core of an ancient planet" sounds badass
Technically, bones ARE rocks when they start out, we just don't usually consider them so. See Dentin; Hydroxyapatite.
1:30 "you are a rock now" there's Shrek joke here somewhere but i'm too sleepy to sus it out.
Great video. Keep up the amazing work. ❤❤❤
I got stuck on the GOLD content, I need to understand this part of your statement more. Researching.......💻
At least your chances of finding a meteorite are greater than getting hit by one.
Sci show needs to make a video on how fish eggs can survive bird digestion and spawn in new locations
Hank is back!
I found a fossil on a job site a couple weeks ago. I walked over it a few times and the small bumps sticking out, which I have assumed to be vertebrae, caught my attention. Looks to be some type of small boney fish with long fins. It's a round rock about and inch diameter. Has me looking in the rocks on jobs now searching for more
Cool episode
Would that make this a sea-bedtime story 😅
"One of us, one of us"
Does this mean that the meat grape would count as a fossil since we removed most of the grape cells and replaced them with meat cells? Hank pls help
1:36 Oh boy! I’m The Rock! Awesome!
Fascinating topic!
Fun fact! Fossil rock fragments from space are a lot more common than you think, but you'll need a microscope to find them because they're dust sized!
Fossil "micrometeorites" are cosmic dust particles that also get preserved in sediment - the best place to find them is in chalk because their black colour contrasts the white "background" calcite grains. There's also a lot of unanswered interesting questions about them and it's the topic of my PhD and masters :D
Great video
Jet Lag needs to take every train in sweden now
Limestone is some pretty cool stuff. You can find marine fossils and impressions all over here in Ohio. I've found some very cool fossil clams myself, and quite a few rocks from quarries with very distinct impressions.
Thank you
So does this mean you could have fossils of earth rocks? If so, I imagine they would be pretty common. Weather or geology moves rocks from one place to another, and the rocks get their structures remineralized by whatever's around them. Or is there something special about these iron space rocks that allows them to fossilize better?
Technically yes we do get "fossils" of Earth rocks its just we call them metamorphic rocks instead of fossils. Specifically mineral replacement metamorphism is the type analogous to what happens with fossil meteorites and bones respectively.
There are other types of metamorphism which involve much more active and dynamic processes like mountain building volcanism and or subduction with high pressure and or temperature conditions, but these tend to involve the recrystallization of the original source rock/material which tends to destroy fossils.
Thank you!
2.8 mm is super small. How did they locate that?
I wondered the same thing. The slices of the core samples must have been really thin and then lots of graduate students toiled away for countless hours laboriously scanning the samples with microscopes. Just a guess.
This man was born to speak for science. HANK
im sorry im laughing when be said "congratulations you are now a rock" lol
"It was a fossil of a rock"
Me: *what*
But it was from space!
Me: *Even more confused*
Come here to sweden, please do!
Gg to Thorsburg for having exactly the name everybody would expect from a Swedish town.
I have seen a small spark of meteorite falling feet feet away while I was looking up in the sky .... God knows where that spark went ..
Quiche.
If an astronaut throws a moon rock at earth.. is that a meteorite attack of terror.. hmm..
Very very cool! Had no idea. Chemistry+time: "Hello rock, you are now a different rock."
How did mineralisation turn a meteorite to gold tho? That is some alchemy type shiz
I know there's trace amounts of gold in seawater, so it's possible the mineral/metal makeup of the fossil meteorite encouraged the gold in seawater to deposit on the meteorite?
I'm no expert on that subject, but my limited knowledge points towards that being the most likely theory within my own head.
@@retrauk That certainly would make a lot more sense than alchemy. Thanks!
The restraint it must have took to add those brackets into the title.
It amazes me to think a core of another planet is here on Earth.
it amazes me to think humans just went about our business for millennia completely unaware of that fact
Heard the voice and was like " bro is this hank???" Yes. Yes it is
The cancer-man himself. 👍
Fossilized meteorite is basically (rock)².
I will go with you!
Man you’re so funny 😂
finally its hank!!!!
I wanna go to Sweden too!!!🤓😉
meteorite fossil sounds very much like a sci-show april fools joke
never knew Meteors could Fossilize
, that is. Cool
Oh, thought we had pieces of the mythical Phaethon...
I can neither confirm nor deny that the GLOMAR vessel was actually hunting for sunken russian submarines.
All rocks on this planet comes from space, the entire planet is located in space.
Video….Video good…me like video.
Somewhere far away from our galaxy, this planets old dinosaur bones are conidered as fossils from outer space
Huh, Intersting title.
more like clickbait
LEGO Exploriens is now vindicated.
Everybody wants a rock to wind a piece of string around!

It's the symbiotes
I just ate an avian dinosaur.
Fried or BBQ? Mmmmm 🐔🍽️🍺
@@JackMehoff-j7w fried.
So they finally found the dinonauts, I guess before watching the video.
Since earth has been enlarged by millions of years of meteorites, how is it even possible to distinguish any part of earth as having come from a meteorite? Why are substances only found in meteorites not already part of earth's makeup?
stuff that forms due to natural processes on a meteor could not occur under the conditions on earth, basically.
Cool
What about Fossil watches?
Niches get fishes!
Hang on Hank, isn't there a hypothesis that the asteroid belt between Mars and Jupiter used to be another planet that Mars may or may not have been a moon too? Mostly as an explanation for both the belt and the extreme scarification on one side of Mars.
Not quite, there are hypotheses about a planet V between Mars and the Asteroid belt, that could explain the late heavy bombardment. It either got ejected off the inner solar system, or crashed into Mars.
2.5mm fosil. I bet they excavated tons of sand, what made this single spec matter
how did they even find it. 2.5mm is rather small
❤❤❤❤❤❤❤
Im sorry, but niche rhymes with quiche not ditch.
Amazing

Ngl me over here laughing at not needing calc to understand a part of stats
Hey, Hank. How has this career of yours, changed your wardrobe? This question is actually for all of the content creators on screen. I'm curious.
I knew getter-energy was a real thing
Im on time
A fossil existing as a fossil? Interesting. 🤔
Für the first time in my eons long existence
I was petrified
He said "it could be a meteorite". So theyre not sure
😊
Thank goodness things turn into rocks or we wouldn't know anything
Rock on! 🤘😂
How do we know what iron in the core of an ancient planet looks like?
the same as iron anywhere else bud
@@jwlsiee if they were the case what would the significance of the statement be? He would just say it looks like any old iron not specifically "iron found in the core of ancient planets".
the surface pattern
