For the majority of their videos, at least, a good 50% of the material presented is completely wrong. I haven't seen this one yet so I can't comment on it directly.

[@madsgrams2069]

Ok, this needs to be corrected. Utahrapor lived in the Barremian age of the Cretaceous, which means over 125 million years ago. That is not in any way "the late Cretaceous", it's actually the early Cretaceous.

[@curtwhite3376]

It’s almost hilarious these mysterious made up ages 120 5 million years 500 million years my ass not when they’re pulling out red blood cells out of dinosaur bones that have not been fossilized. What a bunch of horseshit they’re trying to tell us. Believe what you want. Good luck with your choice.

[@augusth3532]

[@bkjeong4302]

It should be noted that Tenontosaurus was actually significantly smaller than often assumed, so it’s not out of the realms of possibility that even a single Deinonychus would have been able to prey on it on occasion (albeit at VERY heavy risk to itself).

[@rocioaguilera3555]

I've never heard about those dinosaurs. They look more like birds than reptiles

[@Dr.IanPlect]

"They look more like birds than reptiles" - guess what birds are?!

[@azrielmoha6877]

Birds are dinosaurs so you're perfectly correct

[@ExousíaTM]

Oh yes, a video that actually tells good facts about Raptors/Dromeosauridae. Dromeosaurid raptors were my most favourite out of all dinosaurs and animals in the history of the animal kingdom. Raptors were badass looking creatures. From their slendery agile built to the stealthy design and their fast swifting bipedal speeds. We also can not forget their fearsome talons, ready for slashing, Shanking, and stabbing their enemies. Ever since I was young, Tyrannosaurus Rex was my most beloved dinosaur/monster. That's mostly I get intrested really easy at first glance at the time. I have got to thank T-Rex for my interest in dinosaurs. Without the T-Rex, I would have probably never been introduced to Raptors. Once I got older, my interest was more focused on bird avian dinosaurs that were small to medium size like humans, and it was deadly. From mammalian beast in the Cenozoic period to giant creepy crawly invertebrates in the Paleozoic to most famous of them all. Which was a dinosaur, in the Mesozoic Era... mostly the raptors. Raptors were also the reason for my love of avian dinosaurs. Birds of any kind with feathers have always been my favourite subject after I got into Dromaeosaurs. Some raptors may be herbivorus, but that does not stop me from liking them. Life is amazing for having these kinds of creatures to learn about. And I would be very happy to see one alive for the first time in my life!

[@mariagranadoslazo4946]

I just want to say that my son has the Deinonychus in a special place in his heart! 🥰

[@ravensthatflywiththenightm7319]

Hi, could you make playlists for us to binge through later? I would be so grateful. 🦖

[@KAZVorpal]

To be fair, we have no way to actually know if that protoceratops and raptor were actually locked in combat, or ended up that way after death, as in a typical desert flash flood.

[@kennethschalhoub6627]

How is it that the synapsids led to two physiological systems totally different from each other and just as successful? Mammal versus bird physiology is a fascinating subject.

[@Dr.Ian-Plect]

Birds did not evolve from synapsids.

[@sparrowdrone]

Great work but I think Utahraptor is actually early Cretaceous not late

[@jennaseybrechler2792]

What evidence do we have to show what the color of some dinosaurs feathers were?

[@zaiaisho6409]

Consider that darker coloured surfaces attract and hold heat while lighter coloured surfaces reflect light and remain cooler. If a dinosaur were to inhabit a desert environment such as Velociraptor it would likely have lighter sable-coloured plumage to help keep it cool in the heat of the desert and the colouration would help it to blend into its desert environment. Now an animal in a more northern latitude environment such as Troodon, albeit not a raptor but a Dinosaur that would have been found more north of an animal like Deinonychus or Utahraptor would have lived in cooler forested latitudes and would have likely had darker plumage to help it not only to camouflage in its environment but also attract the Sun's rays and heat the animal. It would make the most sense to infer that colour has a lot to do with thermo-regulation.

[@KAZVorpal]

I feel like this video, so far anyway, does not sufficiently emphasize that the best metric for dromaeosauridae success is that ALL BIRDS evolved from them, and could be argued to still be dromaeosaurs. This should change the tenor of some of the video from "Strangely, those dromaeosaurs resembled herons and ducks" to "herons and ducks evolved from dromaeosaurs, perhaps ones like these". At worst, it's parallel evolution, not convergent.

[@beltalowda131]

Love the picture at 19:03. Sleeping while standing on one leg with the other one tucked in, just like my biirrd.

[@tigrecito48]

hey ive just come up with a new theory about how Ankylosaurs got its tail club. I just noticed my dad's dog also has a lump on the end of his tail. He wags his tail so hard hes constantly whipping his tail into things. So my theory is, its not for defence or offense, its purely because they were so happy and they were wagging their tails a lot & just so happened to keep hitting things.

[@kevinchastain727]

funny how none of these are compared to the flightless birds of today like the Kiwi, Dodo, Emus, Cormorant, Penguins, kakapo, and Ostrich. There many more that exist in New Zealand to this day.

[@stoneworld5962]

Cormorants DO fly, and none of these birds are carnivorous except the Penguin, piscivorous. Also "feathered dinosaur" doesn't mean "bird ancestor", despite Microraptor being apparently able to fly, he would be the only dromaesaur (for now ?) who could be clearly compared to birds.

[@Dr.IanPlect]

@@stoneworld5962 - Factually; there _are_ flightless cormorants - Charitably; Kevin is referring to _these_

[@stoneworld5962]

@@Dr.IanPlect Ok, still a bad example of flightless birds since some of them DO fly. And those birds are still far from the topic. We CAN compare a chicken and a T-rex if we want, but what's the point ?

[@crazychrisfromessex1740]

The shape of their skeletons are not as bird like as the illustrations depict. They're tails are much longer, and the arms are completely different. Jurassic Park is more accurate from an anatomical standpoint. Whilst they may have had feathers, they wouldn't have looked anything like the pigeons on this video lol

Kinda weird to call this a documentary, then drop a bunch of "facts" not backed by research. Even using character models from the Jurassic Park franchise without explaining... Atrociraptor from Jurassic World is nothing like it's real life counterpart.

[@stoneworld5962]

He debunked at least 3 JP dinosaurs in this episode, ain't it enough ? Velociraptor and Pyroraptor at least. I'm no specialist but this guy seems to respect the doubts we still have about those dinos, which is cool. But yeah, after a while, we need to be affirmative about some stuf ! 50 min doc always saying "maybe he was like that, if he could do it then he might have been able to, perhaps, if the conditions are united"... uuugh... boring

[@crazychrisfromessex1740]

The wing pictures look way off imo. The claws on the skeleton clearly show arms and hands, not wings lol.

[@Nomad-sw4uy]

Both, actually. The arms and hands had holes in them on which to anchor wing feathers (and these wing feathers are in better quality specimens actually preserved)-- the hands and claws would have been partially concealed by these feathers, like a cat's claws. These weren't real wings obviously-- they were not for flying and would have been instead been used to give them stability when running and allowed for more maneuverability.

[@Swictor]

[@rocioaguilera3555]

There's evidence in many fossils.

[@matthewjohns1758]

There have been a large number of fossils with feathers starting with Archaeopteryx, through the vast number of Chinese fossils; who have just been busy little bees the last twenty years or so digging up new fossils all the time!!!

[@Nomad-sw4uy]

You are correct but in the case of this specific group feathers are ancestral. As such, a featherless dromaeosaur would be like a hairless mammal-- that is, not impossible, but not the "default" state and not as common as the ancestral condition.

[@al20o33]

Yes. Archaeopteryx clearly had feathers. Years ago, the it was found out that the Chinese had passed off a fraudulent fossil having feathers. Therefore, I don't trust all these fossils coming out of China with feathers when none or few are found elsewhere in the World.

[@nightrunnerxm393]

Ehh....I give the JP franchise a pass on accuracy. Two reasons. 1: Every "dinosaur" they depict is explicitly a mix'n'match creature where their DNA is concerned, which means behavior and coloration is inherently gonna be inaccurate (and in the novels, they were also explicitly made more dangerous and ferocious in order to thrill the potential park visitors through even further DNA alterations--and that's setting aside what socialization might do to affect, mitigate, or even pass on behaviors in the smarter and more social dinosaurs) and 2: What we "know" about dinos changes almost year to year. Any accuracy a movie gets is inherently subject to change as we learn more, as the movie is more or less set.Not like the knowledge amassed through continuous study at all...they're just standing on the shoulders of giants, and before they even know what they really have, they've patented it, and marketed it, and slapped it on the side of a lunchbox and they're selling it.

[@eofelis]

I don’t think you’re giving them their due credit. Those scientists did things that no one has ever done before…
