5 Famous Dinosaurs That Aren't Actually Dinosaurs

[@Rubashow]

I remember arguing with my biology teacher about that. She told the class that dinosaurs are reptiles and amphibians. I told her that this is impossible. Dinosaurs are exclusively a branch of reptiles now extict, saving birds. She berated me and gave the student that came up with the idea that amphibians also were dinosaurs a positive remark in his class book. This is now ages ago but this enraged me so much because she was not only totally wrong, she spread her idiocy and rewarded the ones who bought it and she did it all the time.

[@absojake]

You should share her name. The lack of accountability and pure anonymity is causing the stupid to rise.

[@Rubashow]

No I won't share her name. It's been a while and she was notorious for incompetency anyway. If you share someones information on the internet you only invite a mob to bash her and personally she wasn't a bad person and she doesn't deserve it.

[@Rubashow]

I don't even blame her for that. Maybe she had a bad day. What really pissed me of was that she didn't even allow me to prove my point. She appeared frigthened to be contradicted in front of the class ... but I think she should have been admonished.

[@garyking4032]

Rubashow It could've been worse, she could've been mandatorily teaching an 'alternative' theory to evolution...

[@literaltruth]

I find it deeply saddening that such people are teaching subjects they have such limited understanding of. I mean she was not only wing about there being amphibian dinosaurs, but as a biology teacher she should have known that her argument that dinosaurs "are reptiles" is also a nonsense. Biologically speaking there's no such thing as reptiles. There is no way you can define a biological clade that includes snakes, crocodiles, lizards and turtles without including penguins, sparrows, chimpanzees and mice. The definition of a biological clade is that it must contain a species and all species descended from it. The modern species that people think of as reptiles were from an old pre-scientific system where things were clumped according to how they looked and acted - so all the scaly, walking things which laid eggs were put together as "reptiles". However, crocolids, serpents, turtles and lizards are not actually very related at all - and to find their most recent common ancestor you'd have to go back further than dinosaurs (which would mean they and therefore all the avians would have to be included in the clade) and probably further back then the dimertrodon which, as Hank indicated in this video was part of a group that were the ancestors of all mammals. So any biologically meaningful definition of "reptile" would include all animal life except insects and most of the stuff that lives underwater.

[@hebbejebbe]

Yes! As a geologist I love this video. Every single thing that was said was, to my knowledge, accurate and complies with our current understanding of palaeontological history (which is quite rare to see on KZbin videos). A lot of the information that Hank conveys here is actually degree level material. Kudos!

[@nchan4679]

If its so accurate then why do his statements always begin with "scientist believe...."

[@weefslider]

@@nchan4679 Because there's always new evidence popping up that could change what they believe. And since these animals are long, long gone, there's no way we can possibly know anything completely certainly but we can get very close.

[@nchan4679]

@@weefslider well thank you for not being nasty about it. Kinda wierd getting a reply thats respectful lol. Have you considered that a worldwide flood may have buried bones in a manner that would make it appear as if these bones were far older then they actually are? I watched a very convincing arguement on that awhile ago.

[@Nob911]

@@nchan4679 I mean nobody knows anything for certain like science or religion they have the evidence they find and base off that

[@Mgl1206]

N` chan well it’s not really possible. 1 the ground that their stuck in when they fossilized is already old it’s deep enough that it won’t be brought up by a flood. Also these layers of rock can be geologically dated using other data as a reference. 2nd we also use carbon dating bones. While most carbon is a stable carbon-12 (and since from what I know all life is based on carbon) life forms also contain a bit of carbon 14 as well, and using the carbon-14s half-life you can get a pretty accurate age on said finds so the only way to get a false age is geologically but they’d conduct carbon dating pretty soon which would clear it up.

[@charliebartlett5768]

[@Tsumami__]

Stop perpetuating that retardedly oversimplified cliche. Birds still exist, dinosaurs died out over several extinction events. Ffs.

[@mikealphaxray228]

As a paleontology student, I hate seeing videos on youtube where people who don't know about dinosaurs ramble on about them. However, I think I speak for the entire paleontology community in that I really appreciate the overall accuracy of this video. Only one thing: when you said "If it swam, it wasn't a dinosaur." While all the examples you raised are true, that statement is not one we can safely make. We have evidence of modern birds being aquatic, in addition to the obvious example of Crocodilians. Therefore, if we are to stick to dinosaurs' phylogenetic bracket (the archosaur clade), there is nothing preventing certain dinosaurs from partaking in a semi-aquatic or aquatic lifestyle.

[@aaronn]

When I heard that statement I took it as if "If it lived in water, it wasn't a dinosaur"

[@gforce833]

It's just a joke, don't read too much into it :) It's like someone saying "what goes up must come down". Yeah unless you throw it faster than earth's escape velocity, then it's never coming back :P

[@EagleKai]

Yeah, I was wondering about the veracity of that comment. That would be like saying that all Mammals live on the land, which would immediately make all Whales, Dolphins, Manatees, Dugongs, etc "not mammals". Then again, it probably does come down to when and where in the evolutionary tree these creatures decided to return to the sea. If they branched off from a common ancestor, then I could see the claim holding, but if there are some dinosaurs which adopted the aquatic lifestyle then it would only be right to say they're in the same grouping, correct?

[@peachxy3730]

but...crocodilians aren’t dinosaurs..

[@JaylukKhan]

"Anything that swims wasn't a dinosaur." Penguins...

[@bao6461]

Lol

[@Hal2718]

Well I'm pretty sure the implication was that any animal that lives in water isn't a dinosaur. Penguins do not live in water, they live on land. However that doesn't mean that there will never be exceptions. Example: Mammals give birth to live offspring except the platypus.

[@CAWCarcharo34]

He means most of the non-avian except for spinosaurus and a large amount of avian dinosaurs that include today's birds and the Penguins show the evolutionary excellency of a genus from a family evolving because of a new environment

Pretty good information that far too few people know. Although, it's pronounced MOE-sasaur.

[@AbduCola]

This list could've been massive. Duck's, monkeys, dogs, cows, lions etc. I wonder how they narrowed it down to these 5 random animals

[@thehowlingjoker]

Duck's are dinosaurs. Not as easy as it seems eh?

[@darkonyx6995]

Ducks are dinosaurs ;)

Every time I watch a video or program, read an article or book, just plain look at photographic representations of ancient earth, my mind almost goes blank from imagining that monstrous, dangerous, colorful, extraordinary vibrant world. Just like the current world of insects

Yeah, only bigger.

"neup!" I love this guy lol

I'm so glad that mosasaurs are extinct.

Have/Can you do a video on how flight evolved?

Informative. Great job!

[@PizzaManager101]

there were crocodiles that had legs directly under their hips, not flaring outwards, and they were both terrifying and not dinosaurs.

[@zomBgone99]

The asteroid that wiped out the dinosaurs was the SECOND largest mass extinction in history. What was the first?

[@akselploug1518]

Chuck Norris

[@zomBgone99]

Oh.....my........god!

[@comradetortoise]

Yeah, that sucker was horrifying. 95-98% of all life died. Happened as a result of...well basically all of Siberia opening up as a volcanic rift. The resulting cooling (from sulfates, short term), followed by, if I remember properly between 10 and 20 degrees of mean global temp increase (from CO2 release and knock down effects like ocean warming and subsequent methane hydrate release. Long term) bas Baaaaad

[@falnica]

There are several theories, like the one of Siberia, but my favorite is that the came a lot of gamma rays from outer space that make the oceans boil

[@comradetortoise]

That was the Ordovician mass extinction, and it was more like massive radiation poisoning rather than boiling surface waters.

[@samuelaraujomedeiros6682]

Weird fact: Quetzalcoatlus probably only weighed between 200-250 kilograms, which is about 4 times lighter than a giraffe. I learned that while trying to estimate the weight of a Wyvern for a DnD campaign.

[@puppylovergirl303]

Not all dinosaurs couldn't swim - the spinosaurus was a semi-aquatic species.

[@jacksim5759]

the Trex swam in the Jurassic Park book, is that possible? tho in the same page there was the line "all dinosaurs swim" so yeah it had mistakes

[@puppylovergirl303]

+Jack Sim big dinosaurs could wade in water but recently some studies have found that they may have been able to swim, too. Here's an article on it: news.nationalgeographic.com/news/2007/05/070529-dino-swim.html

[@Beowulf0510]

Ceratosaurus was also believed to be semiaquatic to some degree as well

[@aidanfellers8227]

And with the discovery of Halzkaraptor, it adds another semi-aquatic dinosaur to that list, making it only the 2nd knows semi-aquatic non-avian dinosaur.

And Hesperornis was basically a giant killer loon.

[@GamingMasterAnthony]

Brennan Demarest exactly, calling Pluto Pluto is wrong but a lot of people still do it.

[@styk0n]

why didn't scientists name the Quetzalcoatlus something more appropriate, like 'Boeing'?

[@Doomroar]

Because being called after a god sounds more baddass.

[@ittyandpocky]

Quetzalcoatl is the Aztec god of the skies. It's a giant winged snake covered in feathers. Also lol why not Leerjetisaurus.

[@cassiopeaknack]

Dimetrodon ironically was in the latest Jurassic park *sigh* they either watched this video and decided to run with it or didn’t watch this and didn’t care about them not being dinosaurs

[@richardblazer8070]

Jurassic Park has always had non-dinosaur prehistoric animals. They've had Pterosaurs in multiple movies and the first book, which aren't dinosaurs, they've had prehistoric insects like Meganeura in the first book and the locusts in the knewest movies, they've had the Mosasaurus, which is an aquatic lizard, not a dinosaur, and the Lystrosaurus, which is a synapsid, like the Dimetrodon. They've never only had dinosaurs.

Now if every American watched this, the United States would be a little bit less stupid.

[@jakefromstatefarm6969]

Wow. Discriminating someone based on their ethnicity... very smart. Not at all rude or stupid.

[@EternalSilverDragon]

Jake from State Farm If every member of any population watched this, that population would be better educated. So the original comment is correct. Learn what ethnicity means.

[@jakefromstatefarm6969]

The fact or state of belonging to a social group that has a common national or cultural tradition. Indeed I see what ethnicity means. It was rude of me to be mean and I apologize, I'll agree to the thing you said about "if every member of a population watching this, that population would be better educated." I believe that if every American watched this, they would be better educated, the only problem I had was if you were judging a group based solely on their nationality.

[@EternalSilverDragon]

Jake from State Farm Yes, I agree, it's not fair to prejudge people based on things like what country they live in. In fact, if every person in the world watched more education and science based shows, we might live in a better world - with better living standards and less discrimination in general. One can hope...

[@jakefromstatefarm6969]

[@TheAverageAnarchist1]

I have been thinking. Carnivorous dinosaurs are always shown as these extreme, ultraviolent creatures that would attack anything in sight (Jurassic Park). But, what if they were more like the animals that roam the earth today. You can see that lions will attack a gazelle, then feed the pack. But do they attack anything that they see? No, only if they are hungry. So I think that you could probably be a dinosaur, (and as long as you don't catch the dinosaur in a hungry mood) and just go on your way past the t-rex. I am not a professional, I know that. But I made this observance.

[@DarthBiomech]

They could be territorial predators, who would defend their territory from trespassers.

[@slopedarmouredpony]

It's all situation. Modern animated documentaries do portray large carnivores stopping aggression after their target is hunted. They are, however, very cinematic showing them charging large herds of prey animals, causing loads of panic, then everyone slowing down to take a deep breath of grief and relief after the target (or predator) has been killed. The thing is that the dinosaurs would be the kind-of violent collateral damage creatures you would imagine in the movie because, well, they are huge, and their greatest fears were huge. Even the biggest predators are easy to agitate in a world where apex predators just happen to be cannibals as well. Today, since many animals are relatively small unlike in the past, they cannot cause so much collateral damage when agitated, so it looks like they are less violent when really they are too small to destroy anything significant with their violence. Agitating a brachiosaurus is the same as agitating a cow...except that one is several dozen tonnes heavier...

[@cedricfrangi5997]

Let's not forget that they're reptiles and reptiles tend to be protective and sometimes aggressive.

[@DarthBiomech]

Cedric Frangi For crying out of loud, they are NOT reptiles! Hank himself said that some of the flying species was excluded from dinosaurs PRECISELY BECAUSE THEY WAS JUST FLYING REPTILES!

[@cedricfrangi5997]

Darth Biomech I was talking about dinosaurs , land animals , which is what Hank said.

[@drowjack]

That clarifies everything! Thank you!

[@Xcel271]

I think that the "Loch Ness Monster" _might_ possibly be a Mosasaur, if anything.

[@JohnRed]

I think it's more of a fictional plesiosaurs. Loch Ness monster is supposed to have a long neck.

[@sandflapjack]

TempesT OfTheUnholyLight The original discoveries of the lock neck turned out to be zoomed in photos of a toy submarine.

[@karenl2028]

[@rataflechera]

So penguins are the only sea dinosaurs?

[@ShadeSlayer1911]

Kind of, although penguins aren't entirely marine. They are as marine as Polar Bears are, and Polar Bears are pretty terrestrial compared to fully marine mammals such as dolphins and whales. Plus, some prehistoric dinos did swim, such as the piscivorous Spinosaurus, so penguins aren't that unique as far as dinos go.

[@rataflechera]

ShadeSlayer1911 I know penguins are not full marine but I think they are rather as sealions than as polar bears: although they need land for giving birth/laying eggs or rest, their bodies seem more suited for swimming than for dwelling on land; they hunt in water and they can spend several days off shore. But those are just details. I should check pisivorous and spinosaurus for their maritimeness.

[@shadowthehedgehog3113]

Them as well as other swimming birds like gannets, ducks, or Hesperoniforms (extinct). Then there are the Spinosaurids as well as some other Megalosaurs. I don't know of any other aquatic dinos but I wouldn't rule them out.

[@piggyoinkoink6352]

I heard that there was a recent discovery of an aquatic dromaeosaurid that resembled a swan? It was definitely an awesome find (unfortunately they gave it a ridiculous and near-unpronouncable name) 😂
