The Top 10 Weirdest Prehistoric Creatures

[@2DRichochet]

How can you do a list like this and not include Opabinia regalis? The thing had 5 eyes, a backwards facing mouth, a trunk with a "mouth" on the end of it to grab stuff, and was so bizarre that scientists laughed and thought it was a joke when it was first presented in a meeting.

[@williek08472]

Don’t forget Hallucigenia, a spiny worm from the same era so named because paleontologists thought they were hallucinating when they saw it.

​@@PLANET_ODREDS I'm sorry,but what?

[@madsgrams2069]

@@williek08472 Hehe, at least for those two we, more or less, know what they are and where they fit into the animal kingdom. But what about Tullimonstrum? Even to this day, paleontologists don't agree on what it is and the speculations range from weird0 cephalopod with just one tentacle and the mouth placed at the end of it (WTF???), to really strange basal chordate (so something like a hagfish or lamprey, but very, very different, because its mouth is at the end of a trunk-like apendage and also has a sort of pincer-claw acting as a jaw, instead of no jaw at all, it has eyes on stocks and doesn't have the typical worm-shaped body plan that these creatures have) or even actual vertebrate (jawed fish)...somehow.

[@madsgrams2069]

At least Opabinia doesn't actually have the mouth at the end of the trunk-like apendage, which is not something that can be said about Tullimonstrum, which evolved the same kind of structure, but in its case, the pincer-like grappling claw seems to actually have acted like a jaw and the trunk contained its esophagus... Oh, yeah, and its eyes were placed at the ends of of pretty long stocks facing to the sides... P.S. Forgot to mention: it lived in the Carboniferous, not the Cambrian, and, also unlike Opabinia (which was established to be some kind of stem-arthoropod, at least) it has not, to this day, been definitively placed anywhere in the animal kingdom, because paleontologists don't seem to have the slightest clue on what the eff it was and only have speculations (cause its features are not compatible to any phylum of animal we know of).

Those Quetzalcoatlus and Therizinosaurus pictures are terribly inaccurate. Normally, I wouldn't get mad, but this is a science channel.

[@suedonym820]

Reference more accurate pictures then?

[@miri_kess]

According to current knowledge, they are. But there aren't many people redrawing every extinct animal as our understanding changes. Not to mention quality of such pictures - I am not surprised they used nice looking vs "still-not-outdated" sketch. It's popular science thing, like thinking our genom changes only by mutations.

[@5raptorboy1]

Okay, first of all, they're shrinkwrapped. That basically means that the artist decided to give no discretion to what the soft tissues might have looked like. In a real animal, the skeleton is not as pronounced and obvious. This is especially obvious in the Quetzalcoatlus pictures, and to a lesser extent in the Therizinosaurus picture. Also, we can tell from phylogenetic bracketing that it would have had pycnofibres (or feathers, depending on where you put the origin of feathers) which would have looked like a protofuzz. Here is a picture of what they would actually look like (this is coming from not only a skilled artist, but also a palaeontologist): 4.bp.blogspot.com/-OHUhOSWhvIE/Vzdmod7tj2I/AAAAAAAACIQ/V1us1HAbBwkOzle-yon82hgqdYx3DXnmwCK4B/s1600/Quetz%2Bsp.%2BWitton%2B2016%2Blow%2Bres.jpg The Therizinosaurus has less problems. First, the smallest problem is the feathering. It looks like it just had feathers pasted onto the featherless body, which makes no sense. You could make the argument that it would overheat the creature, but its feathers would be advanced enough in order to bypass that problem. The biggest problem are the arms. First of all, the arms are clearly not bulky enough to hold up those claws. Second of all, the hands shouldn't look like that. We can now tell that the muscles in the arms would make it impossible to hold their hands like that. They would keep their hands perpetually in a way that would make them look like they were clapping. Finally, the wings need to be bigger and extend to the second finger. Here's a good picture of a Therizinosaurus ( The theropod in the picture isn't accurate, but the Therizinosaurus is): pre13.deviantart.net/5527/th/pre/f/2012/258/5/d/canada_therizinosaurus_by_stygimolochspinifer-d5eswfo.png While we're here, I guess I'll critique all of the animals in this video. The first picture of Stegosaurus is good. The Dimetrodon could use some updating. The top of the spines would probably be exposed, leading to a half-sail look. The stance is kind of outdated. They would have probably walked more like this:img14.deviantart.net/c40a/i/2015/178/5/5/the_walking_dimetrodon_season_1_to_3_by_traheripteryx-d8yzkma.png Also, more mammalian features are certainly possible. Here's a good (but speculative) picture of a Dimetrodon: orig07.deviantart.net/ba0d/f/2015/205/c/5/dimetrodon_giganhomogenes_by_traheripteryx-d92mixx.png Also, this picture is a little outdated, because now we know that the half-sail look was more like a 75%sail look. The exposed vertebrae would be very small. The Microraptor looks very good. The second picture is bad. First of all, it has way too little feathering. Second of all, the color is wrong. In very well-preserved fossils, we can see melanosomes which tell us the color of the animal. This is very, very rare. Though, we found it for Microraptor, which tells us that it had black, crow-like feathers, and it had an iridescence, similar to modern crows. Also, the picture looks way more like a "lizard with bird wings" than "weird, four winged crow". Here's a better picture: emilywilloughby.com/gallery-data/images/full/microraptor-takeoff.jpg I don't know a lot about Glyptodons, and there weren't any pictures shown, anyway. The Macrauchenia looks good. Platybelodon looks good. No pictures were shown of Megatherium. I actually really like the Anomalocaris picture. Considering that little else had eyes at the time, it would make sense for them to have bright colors since camouflage wouldn't be a problem. All of the info is good. Though, I'm a bit dissapointed that Deinocheirus (img08.deviantart.net/71c9/i/2014/320/0/4/don_t_mess_with_deinocheirus_by_durbed-d84x94w.jpg) and Yi Qi (upload.wikimedia.org/wikipedia/commons/5/56/Yi_qi_restoration.jpg) weren't mentioned! Also, there is a lot of good art of accurate dinosaurs. You just need to know where to find them. John Conway, Emily Willoughby, C.M. Koseman, R.J. Palmer, Mark Witton, and more are all good artists who make accurate dinosaurs. P.S. Phylogenetic bracketing is basically taking what you know about a certain animal and applying it to other ones which are closely related. This won't always be right (in the case of Spinosaurus), but it can certainly help us figure out what prehistoric animals look like. Most animals have very fragmentary fossils and not a lot of fossils, so the only way to create what they looked like is to look at other animals. For example, we only know Dakotaraptor from one fossil found very recently, which doesn't have a lot of bones, but we can tell from those bones that it was a raptor, so we depict the rest of the body like a raptor. The top right part of this picture shows the bones we have found: www.krank.ie/wp-content/uploads/2015/10/Dakotaraptor-steini-skeletal-size-reconstruction.png The bottom left picture is what we can infer and this is what we can infer the animal looked like with soft tissue: saurian.maxmediacorp.com/wp-content/uploads/2013/11/rjpalmer_dakotaraptor_conceptart_001_by_arvalis-d9ev6iw.jpg Okay, is that enough info?

[@miri_kess]

unlike people and most animals insects are kinda like trees in that they will grow as big as their environment lets them, so they should increase in size within the first generation. This is not evolution at play. I have read about this and test have been done. I will try to find a link to something official but you can do a quick google search.

[@rastacoon5962]

Port Kapul In the case you are correct this is reassuring

[@ErgoCogita]

+Port Kapul _"unlike people and most animals insects are kinda like trees in that they will grow as big as their environment lets them"_ This is wrong. Most insects will only grow as large as their genes allow them to, first and foremost. Only then does environment play any sort of role. That being said, the extreme vast majority of insects will not continue to grow in size simply because of high oxygen availability because none of them have any genes left over from the millions upon millions of years of selective pressures in the absence of such high oxygen levels.

[@portkapul1283]

I know I am vastly simplifying things but I can't explain everything, especially on a topic I am not an expert. I was searching for something to quote and this will do "Dragonflies responded to the high oxygen levels, swelling to 15 percent larger than those reared in normal oxygen levels" research.asu.edu/stories/big-insects-provide-big-answers-about-oxygen While this study does show that not all insects increase in size with higher oxygen levels it does support my statement that insects will increase in size if environmental conditions allow.

If i could add some information to a few of these 2. All Pterosaurs could walk on all their limbs, it was necessary for them to take off since they have strong arms for flight, they also used those arms for taking off, which is one of the many reasons they are allowed to get much larger than birds. Skim Feeding in water is impossible for any known Pterosaur, it would break the jaws with such force, Dip feeding is a much more likely candidate for any pterosaur that fed on fish. 5. A recent study shows that Glyptodons are infact armadillos ( www.bbc.com/news/35630712 and phys.org/news/2016-02-extinct-glyptodonts-gigantic-armadillos-ancient.html ) though DNA evidence. 8.

This man's hair should've been number 10.

[@barbarawatkins3636]

I love Edge, its always got the weird, strange and unusual on it. Very interesting to me. Thanx

A Haiku for Quetzalcoatlus: Quetzalcoatlus Not only a dinosaur Grandpa of Big Bird

[@lucaskebow8368]

Jeremy J. Quetzalcoatlus is not a dinosaur. It is a pterosaur. Those two are not the same thing.

[@carterkeller-chicoine2977]

Not only a dinosaur?!?!? It wasn't a dinosaur, so it wasn't a bird o related to birds...

[@eclair6910]

yay this video correctly called them "Saber Toothed-Cats". Thank you for getting science right. One thing that isn't right is suggesting that they used their teeth to puncture skulls. Their teeth were thin and very brittle, as evident from the numerous times broken sabers have been found.

[@bensteinhart9268]

For #2, ALL pterosaurs walked like that!!!

[@keklypuzz1513]

not all pterasaurs walked though

[@officertopheavy3232]

They can't literally fly for their whole lives; so all of them would have had to walk at some point; they may not all have been very good at it, or very fast; but they still had to walk sometimes!

[@bensteinhart9268]

+Argolf Exactly, he/she/it gets it!

[@officertopheavy3232]

Ben Steinhart If you're referring to me; I'm a he!

[@bensteinhart9268]

+Argolf Sorry, HE.

[@GuyWithAnAmazingHat]

I was expecting the Tully Monster, nothing looks like it.

[@wangstanation6400]

yeeet!! a shout out to idaho!!!

[@sebastienh1100]

« Is weird but his mum probably finds him very handsome »... very true of the presenters of Scishow :)

[@Nooneaskedforthis]

Maybe keep the picture up longer so we can see what he is talking about.

[@rparl]

Wow. A lot more dinos than I realized. And the blond lock is back!

[@1631631000]

HERE CUME THE GIANT BEE MOVIE BUG'-' 🌟🌟best joke ever

[@ewan.cartwright]

B-Movie, as in a low budget and fairly rubbish film, not a film about bees.

[@conduit64]

Already exists, "The Swarm" and "The Bees" both 1978.

[@NessaWyvern]

8:29 A wild Anorith appeared!

[@TheLinnux1]

Ark anybody?

[@genessab]

TheLinnux1 what about it? An incredibly old myth first described in the epic of Gilgamesh and stolen for the book of genesis, an incredibly inaccurate, metaphor filled creation myth of a herding society?

[@oscarsamaniego2048]

Vikings488 Ark: Survival Evolved. It's a game.

[@Guru_1092]

Hey! The Glyptodon was in Ice Age. So that's what that turtle thing was.

[@august-5085]

so much of these things are in Ark

[@Aamedin100]

I'm impressed--most videos on KZbin get evolution so horribly mangled it's hard to figure out where to start correcting them. This is a very well-researched video; thank you! I will say that your explanation for why these creatures no longer exist is at odds with the standard explanation in paleontology. It's not that these creatures were adapted for environments that no longer exist (though that was true of the Ediacaran/Vendian faunas--so weird we still have no idea what to do with them when we're being honest with ourselves!). Rather, it's that the organisms--for a myriad of reasons--that had these body plans died out. Unfortunately, we can't say precisely why; most likely there's no one reason. There's no reason to think that any of these body plans (outside the giant arthropods, anyway) wouldn't be viable today, if they had survived. This may sound trivial, but with the discovery of stromatolites on Mars (yeah, I know, it's tentative--but I'm willing to say I'm convinced if only to see how it's proven wrong!) and evidence of life on Titan (not STRONG evidence, but enough to make alien life there a very real possibility folks at NASA are looking into) it's important to remember that chance plays a HUGE role in life history. What we see now is only normal because it's what we see; other plants need not follow our evolutionary pathway, and even similar planets may hold life that is nearly incomprehensible to us.

[@Blackmark52]

Nothing personal, but especially since this video is titled _10 Strange-Looking Prehistoric Animals_, it would have been nice to show more of the prehistoric animals and less of the modern human.

[@gregdison]

I really love this buzzfeed video.

[@arodrigues2843]

Interesting video, BUT too much time showing the guy, and very short time of the species' images.!!! Should be the other way around.!!!

[@williek08472]

Platybelodon and Anomalocaris are two of my favorite prehistoric animals just because of how crazy they were.

[@ralfjuh9033]

So almost all the animals here are in Ark

[@RoonMian]

You could make an episode about the mouth of Anomalocharis. I saw it in a documentary once like 20 years ago and I still have nightmares about it sometimes.

[@johannpecan2049]

ARK

[@TheFlamingDraco]

FINALLY. Someone who gives there sources.

[@koibutsu]

can you freaking keep pictures up longer and not so blurrred out

[@LlNDEN]

Awesome episode!

[@darkmega24ify]

Anomalocaris looks so much like the Fossil Pokemon Anorith. I guess that's where it got its inspiration in appearance and name.

[@Snakeyes244]

excellent episode

[@rebeccalopez3397]

hello, I bare no ill will, this was great and informative ! I learned a lot ! but, if I may suggest, it would have been nicer to see more pictures of the animals

[@angiecontreras9324]

ok so, i love this channel. i want to see the pictures for longer than half a second please. i love the presenters, very nice, but also, pictures. please

[@codeman7055]

I already knew about the first 9 animals, the shrimp was the only thing I didn't know about.

[@_hector__]

This is the best top 10 channel and its not even a top 10 channel.

[@alicecuriosityoftenleadsto6288]

How the hell a coprion used it 😂😂 I love the little hidden 'puns' in these :)

[@jasminelarsonion8400]

Thanks for delivering such interesting information with such sexiness Mr. Arranda 🤟

[@duhduhvesta]

love this. more please.

[@saulodoamordivino]

Game Freak, take notes. I'm sick of fucking sets of keys and ice cream cones.

[@gigaroni]

I like to imagine the Therizinosaurus trying to get rid of an itch with those darn claws... I call them "tickle chickens" FOR A REASON!

[@nuagor]

Interesting stuff! They should keep the picture of the cool animal in a sidebar or something while he talks.

[@VAB0L0]

I can't be the only one who was reminded of the Hork-Bajir when Michael described the Therizinosaurus, right?

[@marvalice3455]

a note on Pterosaurs, the current thought is that most walked on their forelimbs while on the ground, this would be less awkward for walking and would let them put their much more developed a arm muscles to use so they could minmax away the muscles on their rear legs. if so this would explain why they could get so much bigger than birds who have to be more balanced because even if birds don't spend a lot of time on the ground, they are still built to use their legs to take off.
