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.

[@Distant_Frontier]

He is just using popular animals for views

[@akindlylettuce8142]

​@@Distant_Frontier 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).

[@mistformsquirrel]

The anomalacaris looks like something out of Spore as-is...

[@JustGrowingUp84]

mistformsquirrel Lol, I knew they reminded me of something!

[@euclideansquid8667]

Honestly when I saw that model of anomalacaris, I immediately thought of the Pokemon Anorith, but you are right it looks like something you can easily make in Spore.

[@mistformsquirrel]

TheFilthyCasual Actually, come to think of it, some of these show up in Ark: Survival Evolved. Not all of them, but I believe Quetzacoatlus, Glyptodon, and Megatherium are all present and, I think, tamable. It's been awhile since I played mind, so I could be mis-remembering things a bit.

[@shawnc1936]

+mistformsquirrel yep and fairly accurate based on this video. Some assumptions made like the quetzal in the game does fly. But that's to be expected.

[@iamsparklyunicorn]

If that giant millipede were still around today, I'd gtfo & head to Mars or something

[@mikvance]

We'd have to nuke Earth from orbit. Its the only way to be sure.

[@varnageT]

what about the giant cockroaches on mars that are threatening humanity?

[@sacr3]

Don't be silly, you'd be completely comfortable about it because it would be the norm, but you'd probably fear it just as you would any other large carnivorous animal or insect. Now, if it just "appeared" today, then yes people would be terrified.

[@ShadeScarecrow]

Heck no, place a comfy chair on its back, hold a carrot in front of it, bam, awesome Millipede transportation xD

[@Mental999Man]

have you seen Terraformers? there are giant humanoid genocide-loving nazi cockroaches on mars.

[@martinshoosterman]

Its cool how through billions of years of evolution, and even though the giants of the world are all thought to have lived long ago, the largest animal ever still lives on earth today.

About #10: The most exciting discovery about anomalocariids in recent times is the discovery of a fossil from a German lagerstatte (a place with lots of really good fossils) that shows an Anomalocariid...in Devonian rock. So they lived for a hundred million years after we thought they went extinct.

And then you cry alone in your sleep surrounded by useless trivia about dinosaurs. It's okay, buddy. I know a bunch of useless trivia too.

[@5raptorboy1]

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]

Thank you sooo much for names of reliable artists. It is a lot easier to find good quality if you know what you re looking for. And, side note, I just realized it has ben few long years sice dinosaurs feather update. Wonder how long till it replace current image, hope not 2 generations.

Millions of years from now it'll happen to us. When all the climate changes and asteroid strikes have changed earth and the dominant species, the platypus, does archeology, they'll laugh at the bill-less tail-less bipedal creatures they unearth.

[@donotcare57656]

This is incorrect. If the platypus/platypi/platypeople/platyWTF developed intelligence, they would look in the mirror, and just think "WTF is wrong with us?!?!?" and then kill themselves.

[@TorquemadaTwist]

[@rastacoon5962]

What would happen if you put a mating pair of arthropods in an oxygen rich tank and waited for a few generations? Would they grow huge? Someone test this, please, now I have to know.

[@portkapul1283]

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.

[@XBOXGAMRS]

Evolution is based on chance and need, not need and want

[@DanteYewToob]

In the future could you show the pictures of the critters a bit longer? You show it so fast and lose it and just talk about it, when you could leave it up as you describe and explain it so the image sticks a bit better. I kept having to pause and go back and even google extra images to get a good idea of what they really looked like. Either way, good video as always. I love SciShow.

[@viyusavery248]

ummmm they discovered that some prehistoric bacteria/microbe creates some kind of chemical substance while it metabolizes that can cure cancer, aids etc but the microbe cannot exist for too long in a test-tube so it needs its original host(s) which are the weird dinosaurs in this video, word got out of the project and sadly it was a project too ambitious and threatening for major pharmacy companies that thrive on the profit of expensive ineffective treatment that needs constant installments Using their money/influenece/corruption these pharmacy leaders got the president involved so as to shut down the operation and threatened their life if they did not cooperate, with their passion still in check they agreed with nods but in their hearts they had other plans. they decided to use all their life savings and got aid from others who believed in the potential of the project(in secret of course) the plan was to continue operation in a place where little or no humans trod(like some amazon or something) eventually a destination was set, it was on the island "ukygraewhiearewi"(i cant think of an exact place lol) they "moved in" deep deep into the lands with their heavy equipment etc and they successfully set up thanks to an escort called Roceth who stared them away from the grounds where the "uncontacted" tribe ujuk trod, after months/years they successfully recreated the habitat for the dinosaurs and started to work on the cure(s) but something went wrong and the dinosaurs went on a rampage destroying equipment etc, running for their life they crossed path with the savage meat loving ujuk tribe, being the savages they are the ujuk tribe took down the rampaging dinosaurs that were attacking the scientist. but the scientist were next to be attacked.. but thankfully Roceth was around and spoke their language, the tribe master trusted him and offered them refuge motivated to learn to defend themselves like the ujuk, the scientists adapted to their lifestyles etc some became comfortable and almost forgot about their old lives but this kindness backfired on the ujuk tribe as they fell ill and some even died from the common cold that the scientists brought to them , so the scientist now with new "tribe skills" made a plan to go back to the research grounds fighting dinosaurs on the way to provide the tribe with treatment and eventually leave the island and give up on their dream to sure the world the end :D

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. I'm surprised you didn't mention the bones embedded in the skin that would act like chainmail.

THANK YOU the only video that actually talked about theriznosaurs

[@LlNDEN]

Awesome episode!

You think anomalocaris was weird? You should see opabimia.

Evolution is an odd thing

because it false

+Marie Belfond really. freaking stupid. im christian and beleive in evolution. it is real so ur straight dumb.

[@falaqueeuajudo]

you're funny, Marie

[@briangarrow448]

+Marie Belfond Stop lying. You know damn well that evolution has been scientifically proven repeatedly. your statement makes you look foolish, stupid,or a religious nut case.

[@tomasbdepaula]

Important correction: actually many arthropods DO have circulatory systems. This includes chelicerates and crustaceans, for example (remember horseshoe crab blood?). Insects and myryapods (mostly) lack hemoglobin and hemocyanin, so those guys do rely on diffusion via their tracheae.

I love Michael Aranda and I love weird dinosaurs. This was great.

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.

[@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!

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...

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

excellent episode

A lot of these are in the game Ark Survival Evolved haha!

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

[@ThatJaymsWisdom]

Love this video.

[@shaneadams589]

I loved this video!!!

[@august-5085]

so much of these things are in Ark

[@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?

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

[@flatflatspin9855]

Good show! :-)

[@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

[@ralfjuh9033]

So almost all the animals here are in Ark

[@koibutsu]

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

[@faithcantrell8378]

#5 and #6 are in the second Ice Age movie and you just don't know how happy that makes me

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.

[@sebastienh1100]

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

[@Guru_1092]

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

[@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.

[@darkmega24ify]

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

[@mikel6668]

great video

[@gregdison]

I really love this buzzfeed video.

[@CotaViking]

Awsome!!

[@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

[@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.

[@likhi13]

I love this show😘😍

[@iCanHasRandomness]
