- We know that fossils are fragile, and volcanoes are destructive. So you wouldn't think that volcanoes are really any help when preserving fossils... but you'd be wrong! From the Laetoli Footprints to the Blue Lake Rhino, here are five fossil sites that only exist thanks to the destructive might of volcanoes.

A lot of people have pointed out that children will step in someone else's footprints for fun, but there is another aspect to it. Sometimes ground can be uncertain, but, if you've just seen someone else bigger than you step there without any problems of slipping or sinking, then that is a safe place for you to step as well.
Pretty sure that is not what kids are thinking. That is what you are thinking. Not the same thing.
I'm surprised nobody has remembered that sand people walk single file to hide their numbers.
@@Tugela60possibly some sort of instinct. Very old ones barley ever used
@eotwkdp Not an instinct. It is something called "fun". It is a game.
@@Tugela60 , you don't have to consciously think something for it to be a reason behind an action.
3:58 who hasn't ever steped into someone else's foodprints in mud/clay as a child? This seems so very... human.
Exactly my thought!
🤤mmmmm... food prints... 🤤
This phenomena is actually mainly only done by humans. While many animals will follow trails, they will almost always create their own tracks instead of using tracks already established
Clearly the Laetoli people were superstitious. Even pre-humans knew it was bad luck to step on the line. You either step completely inside or completely outside the footprint. I bet the Laetoli also gambled and did drugs.
@@DemPilafian You know, almost as silly as that sounds one of my favourite food channels that travels the world to learn about traditional food cultures including many still functional tribal ones laughs that (politely) that humans have been seeking "drug" items for pretty much as long as there have been humans
The Blue Rhino Cave is so amazing because it has a creature literally become their own mausoleum with the bone remains housed inside?! Since the rhino was already dead it's a beautiful happenstance of memorialization.
it's almost similar, as in Pompeii they create the "bodies" of the Pompeians
That rhino definitely died from the volcano. Just not the lava
@@gilliesiut2332It may have died from something else and been washed down a river and into the larger body of water where the lava pillows were forming. Pillow lavas can happen when there’s nothing going on above the water. It also could have died from volcanic activity on the surface. Without any soft tissue, it’s hard to tell cause of death sometimes.
I love that we have evidence of one walking in the footsteps of another. Makes them feel real because we can start thinking of their motivation. Was it easier to step in the foot prints instead of untouched mud? Was it a bored child? Were they stalking/tracking the first traveler? So interesting
I was thinking they where caught in the ash storm so they had their heads down and just stepped in the same path on instinct
The phenomenon of tree trunks turned into "caves" is quite common in the copious lava flows of Mauna Loa and Kīlauea Volcanoes on Hawai‘i Island. They are called tree molds, you can find them all over the place! I've even found a perfect impression of a hala (pandanus) fruit in lava rock.
Wow
cooooool
Lava turned one ring into a new golden age of man
That's the opposite of preserving it. Now that one silmaril...
@@DefinatelyNotAI One? There are lots of silmarilarites.
Lord of the rings
I've been to Ashfall Fossil beds, a really nice set up with an air conditioned building over the major finds so you can walk around on a raised walkway and see all those poor animals where they died. There are often students excavating the skeletons who will talk to you about what they're doing. Clean, well laid out and an outdoor area with bronze sculptures of the animals found there.
Ancient footprints intrigue me even more than fossils because they show the preservation of a specific moment in time, not just the body of a creature. It really gives me goosebumps to think about.
Yeah, an event. Here was ancient life doing it's daily grind in that exact place, millions of years ago. And you are at that same place now.
I love your perspective!!! I will think of this next time I study fossil foot prints/trails! Amber is pretty amazing too if you think about it. especially large intact specimens!!
Sometimes you get both. Some fish fossils were found in North America with tectites in their gills. They appear to have been buried very fast. The fossils are about 66 million years old. Tectites are a type of meteorite ejecta.
I learned from Gutsick Gibbon that the common ancestor of humans and chimpanzees wasn’t a knuckle walker. That trait didn’t develop in chimps until after the split.
The foot prints remind me of when me and my father where traversing through snow when I was young and I followed in his foot steps because it was easier and allowed me to keep up without tripping as much
My favorite are the foot prints at White Sands, where there were animal prints going across the human ones including a giant sloth. Those poor kids must have been so scared...
@@gl15col The sloth could have been there a few hours later. Or the child already knew those sloths existed and did typically not attack humans.
Children nowadays can learn about horses and then gleefully walk up to them and kiss them on the nose.
Yeah....... giant sloths WERE NOT docile! They were far quicker than sloths today and they were opportunistic and would EAT people when given the chance. Also, humans hunted giant sloths.
@@jessicapearson9479 Do you have a source for the people eating sloths? Do we have archological evidence for that?
And that humans hunted sloths only supports my hypothesis that the children were probably not afraid of them. They've seen their parents kill those beasts and serve them for dinner.
under the right conditions, a Pyroclastic Flow is _perfect_ for preserving bones! it instantly incinerates everything else, but for thick bones it can be great! AND you can get animals "frozen" in mid action, such as locked in battle, birth, or... the act that precedes birth... 😳
Walking through something loose and bulky like snow (or presumably ash) is easier when you can step into the prints of someone breaking trail. Out on long walks through the snow we would take turns breaking trail while the rest followed in the tracks for a more restful hike. It's also good because if there is a risk of stepping in a covered hole or something sharp, the tracks of the one in front are essentially guaranteed to be ok.
Maybe this has since become outdated, but I remember learning that Pompeii received falling ash, whereas Herculaneum received pyroclastic flow. The vulture head preservation would be more comparable to the scenario in Herculaneum than in Pompeii, for what it’s worth (assuming what I learned is still the prevailing theory).
Why would would you step directly into the foot steps in front of you? For the same reason we would. It was something to do. I’ve found myself doing it while on hikes in soft ground. For no real reason other than light entertainment
I hear sand people do it to hide their numbers
That and it is often an easier path as well. And you know it's a safe one because someone's already stepped there.
That's the interesting part though, we're talking 3 million years ago and yet it's a behaviour that's so very human. It shows a level of understanding and intent that's cool to know even our far earlier relatives had.
Yes,especially during a volcanic eruption. The ash compressed by the person in front would give a safer foothold.
They could also be tactical. Hiding numbers. Chimpanzees have territorial conflicts. Assuming our early human ancestors could have as well.
this thing about the "lava molds" of this poor rhinoceros makes me remember 2 things: one the "casts" of Pompeii and the molds for Easter eggs, you might get an easter rhino!
Y'all are the bee's knees, SciShow crew! Thank you for all you do!
What kind of bee? Is it a previously unidentified one trapped in amber?
pain in the ash...
Rest in ashes
All that remained were ash holes.
Then they started to uncover the ash holes
When I was little and saw someone leaving prints then I would do everything I could to step in those same spots. It was good entertainment in the pre-interent days! Willing to bet thats what our young ancestor was doing.
I live in Idaho I've been to the Bruneau sand dunes and fossilized lava and it's eerie!
Fascinating how something as destructive as volcanic activity can contribute so significantly to preserving our historical ecosystems. The violent eruptions creating beautifully preserved fossils is truly intriguing.
the magma footprints were so much cooler than I expected
The snark when explaining the name of the site was unexpected and perfect.
And the award for coolest way to be preserved goes to....
It's certainly up there. I think bogs still get my vote for number 1 though.
It's Stefan! ❤ Thank you for explaining the Lava/ Magma footprints.
A rhino into a cave okay im interested
Me too let's see how it happened
A rhino shaped , rhino sized cave is my prediction
Pneumonoultramicroscopicsilicovolcanoconiosis!! (I say as I wildly point at the Ashfall Fossil Bed segment, finally getting to use a word I learned in high school for absolutely no reason.)
when I was a kid I always felt like that word was kind of cheating somehow because it has a suffix ("-ic") in the middle directly followed by a prefix ("silico-") which isn't supposed to happen ― I thought it should have been two words, "pneumonoultramicroscopic silicovolcanoconiosis"
@@flamingspinach I mean, everyone knows scientists are notoriously bad at naming things. I'd put 5 bucks on that word being the way it is because someone forgot to put a space between two words when they first wrote it in a paper or something.
@@flamingspinachYou're right that it's cheating. It uses microscopic when the combining form would be micro e.g. microbiology not microscopicbiology, c.f. nanobot not nanoscopicbot.
Adding: pneumono- should be pneumo-.
@@11amasuperboyYou owe me and @flamingspinach, who I'm sure would have taken you up on that, five bucks.
You're being unnecessarily rude to scientists by saying they forgot a space on the double grounds that the space wasn't forgotten and it wasn't scientists. It was made up as an unnecessarily long word by a guy who was president of a society that made puzzles and did word play. It's a pointless word because the medical condition it purported to name was already called pneumoconiosis or silicosis and ironically volcanic ash is less likely to cause silicosis than other forms of inhaled silica.
@@igrim4777 "It was made up as an unnecessarily long word by a guy who was president of a society that made puzzles and did word play."
Yup, that tracks. It smacks of those lists of obscure phobias you see floating around, where 99% of the supposed -phobia words were made up by someone for the sole purpose of being included on lists of obscure phobias and have never been seriously used in a sentence by anyone, lol
Or actually, for that matter, to cite a much older example, all the supposed group nouns for different animals (a "murder" of crows, an "ambush" of tigers, a "scurry" of squirrels etc.), which were actually mostly made up by bored English aristocrats in the 14th century and eventually published in a book called the Book of Saint Albans which then proceeded to be taken seriously by people hundreds of years later, somehow
rhino death cave would be a good name for a metal band
Stepping in other people's footprints also has 2 interesting characteristics.
1) It's easier. Any rough or unstable ground you have to do more force stepping and removing your feet, so stepping on already compressed ground requires less effort.
2) you can hide your presence. Tracking footprints are a classical way of finding your prey.
Along other reasons.
Just wanted to do an extra shoutout to Mclaren Stanley for making it so that I can enjoy this amazing content for free. Thank you.
There are caves made from trees near Mount St helens. I've crawled inside one!
No mention of pitchstones? They are pretty much a slight deviation in composition to obsidian and, iirc, ones found in Scotland can contain ammonite fossils inside them. Well, to be fair, you can find those buggers everywhere in Scotland.
2:26 There were Elephants in Arizona back in the day, too! And that's no oceanfront property joke!!! 😊
In fact, there were elephants in Arizona as recently as the end of the last glacial maximum. Considering they arrived in South America 3 million years ago we know they survived many ice ages events. It wasn't until just recently, geologically speaking at least, that the went extinct here.
Did he just say Nevada used to have camels?
Yes.
Probably migrated to Asia when the land bridge was formed
Eruption, pyroclastic flow...
Add animals...
Shake and Bake!
Thank you, McLaren!
Thank you to who ever voted for the current president of science
I knew Hank wasn't human!
Mclaren Stanely, thank you very much. You help where I cannot.
"Why are there dinosaur tracks on the ceiling?"
*eye them suspiciously*
"Spider Dino, Spider Dino, doing what a Spider Dino does."
The instant I saw the title, I knew it had to refer to my state's Blue Lake Rhino :)
Do you know if it's open to the public to visit?
@@slwrabbits It's a trail, straight up a rock slope, with lots of rocks to scramble over - and rocks often fall down from above. So it's not recommended for most people.
@@caseyleichter2309 Thanks, good to know. Well, at least this way it won't be ruined by tourists ...
I've done the hike/climb up the cliff to go to the rhino cave at Blue lake back in 2015. It's quite the small opening to crawl through and then it's just barely big enough for two people to fit inside. The bones apparently are down in California at some University collection. There is also a fiberglass reproduction of the cave at a museum in Seattle.
Great Episode! 💜
What a facinating episode.
The mechanics of the world are truly fascinating.
I went to Ashfall with my lab and my dad, we were the only people there so we got a personal tour and every paleontologist made the same joke about my dog wanting to steal a bone from the site. 10/10 would go again
'Fear of getting cast in lava' does sound like it warrants a '-phobia' scientific name.
6:55 But it also sounds like a great way to preserve your likeness after passing.
Dilemma dilemma.
"And the rest is history" says Scishow after explaining something more historic. 5:07
great title and content, hadn’t heard about these kinds of fossils
I have been to Blue lake HUNDREDS of times. I lived in Randle most of my life. It has a pretty difficult ATV/ Motorcycle trail to get to it. Had NO idea that was even there.
Edit : This is Blue lake in Eastern Washington. Near Dry Falls.
I was once or twice in some ash rain...scary is all i could think of but we were all fine
McLaren Stanley is the first scientist to discover you can suspend a penny on top of a proper pint of Guinness.... A Eureka moment of scientific inspiration and discovery!
Dude, I want to be a cave...
That should be a burial option
Being entombed in lava sounds like the most uncool way to be fossilized... Pretty damn awesome though.
Wow, that was unexpected (about magma tracks)
3:57 "...and a third individual followed. What's funny is the third one stepped directly into the larger footprints that were already there. But we have no way to know why they did that."
I think Obi-Wan Kenobi could shed some light on this:
"Sandpeople always ride single file to hide their numbers."
Thanks prez Stanley 🤙
As soon as you mentioned pillow lava, I knew that poor rhino didn’t go the way of Gollum. It makes you feel less sad than the fossils from pyroclastic flows and ash falls.
if I remember correctly, one of the very earliest domesticated goats was buried and preserved in an eruption.
Unfortunately, the Blue Lake Rhino probably suffocated in agony in the eruption fumes only a few hours earlier - anyt longer and its carcase would have been predated.
11:25 This explanation of the principles behind preserving ancient footprints somehow reminds me of the photolithography process in semiconductors (lol).
Oh hey you mentioned Bruneau in Idaho! That’s where I rockhound. Look up Bruneau Jasper if you wanna see some very unusual non-fossil ancient information
This hole, it was made FROM me!

🎉 Woohoo Mclaren Stanley. President of Science! 🎉
Thank you!
best title ever scishow well done! lmfao! i was like oh yeah "clickclickityclickclickclick" SOLD!
"It was already dead"
Good to know we now have cruelty free fossils.
Hi Stefan!
That video title is a sentence I bet nobody every thought they'd be reading much less typing out lmao!
That said though you mentioned Blue Lake in Washington and it clicked in my brain that I knew what you were talking about since I've been to Blue Lake a number of times as a kid.
It's a really cool area to visit if you're ever in the region and there's some good fishing in a lot of the lakes in that general area.
Washington actually has quite a few really neat areas for folk who like ancient history and geology!
The scrublands in southern Washington for instance are largely the bed of an ancient glacial lake from the end of the last ice age.
For a second I thought that Hank was finally elected president of science.
Saving to watch later it's almost 6.30am need sleep lol but too interesting 😂
I've been to the rhino cave!
Thank you, McLaren Stanley
Can we get a Crash Course: Geology?
Pretty sure I saw Rhino Death Cave at a music festival back in the '90s.
Reminds me of the footprint in Quartsite Arizona
That's it, instead of a grave stone, I want a statue made of me, after I die.
As someone who grew up whit alot of snow, I can tell you that in a deep snowfall, young kids who don't want to get snow in their boots step in the tracks their parents or a friend
Well, there you go...magma footprints! Pretty neat, huh? 😊
Cool!!
I remember when I first went to the Burke Museum over 10 years ago, they had the rhino cave on display.
Sadly, when I went there a few months ago the rhino cave seems to have been excluded from the post renovation displays (unless I am stupid and missed it).
Fine Scishow, you've intrigued me... go on. 😂
I didn't know there was anything in Nebraska
There are a lot of Cenozoic fossil sites here in Nebbyraska. Also, we have Carhenge.
There is, but it's all just stuff planted in the dirt.
Henry Doorly Zoo in Omaha, world class with lots of new, open area enclosures and they have gorilla babies every year. The zoo is involved in lots of endangered species breeding programs and the grounds are quite lovely.
Dirt. Most dirt has some stuff in it if you dig enough.
I am from Australia... Nebraska doesn't exist it is a conspiracy from the world government trying to make you believe the world exists.
Thank you, President Mclaren!!! 🥰
You can't make a video on this topic and not mention the dude in Pompeii that was preserved while rubbing one out. A true hero 👏
I'd imagine the floating rhino was killed by the eruption, with a lot of trees in the water, almost sounds like a land slide or something
Like if you want to be instantly covered in a hot but not too hot pyroclastic flow, leaving your impression inside the rock for the future generations to study.
Epic
Somewhere in Afrika there is the imprint of a whole elephant herd that was surronded by a very fast lavaflow. You can even see their trunks.
I've seen the same scenario but with trees.
It's called lava cast there.
It's my favorite presenter 💯🔥
It sounds so much worse to be buried by volcanic ash that's only almost 200 degrees.. That must suck compared to a more instant death at higher temperature
I hope you all find a way to save the microscope show, I cannot believe you are letting it die.
microcosms is the best
If they lived long enough after they inhaled the ash for them to have new bone growth afterwards, how long did it take them to die? Them all dying close to each other would suggest they died at the same time, but their having new bone growth would suggest it took some time for them to die
Saber tooth : I looked away for one second after that explosion and suddenly there's a whole new location ...
4:50 or maybe, like chimpanzees, they're capable of walking upright but don't prefer to, but because it was sticky they wanted to keep their hands clean
Idk if using this one instance proves much of anything :/
Rhinoplastic flow.
Imagine someone finds a t-rex lava cast
It's rare I'll click into a video for the title alone, but here we are.
Thanks for the video! I appreciate the fact that you guys need to advertise, but the new ad breaks are jarring and I find myself just clicking on to another video when they come up. Needs more segue.
