Pterasaurs didn't have quills, they were covered furry downing of pynofibres, it wasn't a few scattered quills, it was an entire body covering. Pterasaurs are placed quite close to dinosaurs and other dinosauriforms I would not be surprised if similar such filimentous coverings were present in these archosaur groups and later evolved into the proto feathers of dinosaurs.
I do want to note that more information has come to my attention since making this video. I did a bit of correction in my Plateosaurus video, and will be better in later Triassic videos.
5:26 I would say very possibly since pterosaurs had filamentous fluff similar to feathers so its possible that early dinosaurs had bristle like feathers. Nature never fails to suprise us.
DISCLAIMER: It is still debated whether herrerasaurus is an actual dinosaur or just related to the clade. Some place it as a theropod dinosaur. Others place it as basal to the sauropods. Others don't even consider it a true dinosaur.
"Mammal-like reptiles" is incorrect terminology, because these were not reptiles. "Reptile-like mammals" would be more accurate, or even better "Synapsids".
You are right that I used a common phase that is incorrect. I will be using terms like “reptile-like mammals” or “primitive mammals” in future and restrict “mammal-like reptiles” to non-mammal synapsids.
Thanks for the correction. As my first video this has a few mistakes. I missed the 2011 reassignment of Saurosuchus from Rauisuchian to Loricatan, and in my later videos I try to be as up to date as I can be.
It probably would have been warm blooded because: All dinosaurs appear to have been warm blooded to some extent, so the early dinosaurs probably were. The scleral rings around the eyes indicate that Herrerasaurus hunted at dusk and dawn, times that cold blooded animals are sluggish. Dinosaurs originated in places with lots of available food, good for supporting high metabolism warm blooded lifestyles.
The arrangement of the hips of the bird-hipped dinosaurs looked like those of birds, more so than most theropods and sauropods that were known when these names were given. Derived theropods, like dromeosaurs, evolved a pubis that pointed backwards that more closely resembles the hips of modern birds. I talk about this more in my Deinonychus video.

@@palaeo_channel Sounds good, your videos are very enjoyable and your research is pretty spot on, the intros are a nice touch as well.
Great images, and quality information. I'm very curious about the triceratops
An excellent video. Full of information and well produced. Looking forward to more.
Very good and interesting!! The perfect amount of information to learn more about the most famous (and some less famous) dinosaurs :)
Very good! Loved it.
I’d like to see an episode about Stegosaurus or Ankylosaurus.
Gostámos muito do vídeo . Os nossos alunos gostavam de saber mais sobre os dinossauros. Podem colocar o vídeo com legendas?
Very nice video, always nice to relax to some well informed dino talk. I'd very much appreciate some carcharodontosaurid, or abliasaurid talk.
It was very informative! Can you do one on the diplodocus?
Cryolophosaurus is one of my favorite genera of theropod. :)
Cryolophosaurus is very interesting, and I would love to do a video on it. It may take some time to get to it, but I do love the weird and wonderful.
@@palaeo_channel Awesome. You're a cool dude. Love the vids.
My favourite dinosaur is a toss up between Ankylosaurus and Allosaurus so if you could do a profile on this then it would make me a very happy man.
I come from the future and I can tell you that you will be very satisfied with both of your wishes.
These are the best videos ever

I do attempt to explain this around 2:45.
Fixe. Gostava de saber mais sobre os dinossauros encontrados em Portugal. Sabes alguma coisa sobre as pegadas da praia do Magoito.

You should try a velociraptor video.
I talk a lot about Velociraptor in my Deinonychus video.
Please get the facts right. Saurosuchus wasn't a "Rauisuchian". It was a Loricatan however.
Thanks for the correction. As my first video this has a few mistakes. I missed the 2011 reassignment of Saurosuchus from Rauisuchian to Loricatan, and in my later videos I try to be as up to date as I can be.
giganotosaurus,mapusaurus,charcarodontosaurus ,tyranotitan ?
Hi Andrew would Herrerasaurus be warm blooded
It probably would have been warm blooded because:
All dinosaurs appear to have been warm blooded to some extent, so the early dinosaurs probably were.
The scleral rings around the eyes indicate that Herrerasaurus hunted at dusk and dawn, times that cold blooded animals are sluggish.
Dinosaurs originated in places with lots of available food, good for supporting high metabolism warm blooded lifestyles.

Subbed.
Most young animals have large heads compared to the adult of the species.
Beep boop goes the UA-cam Algorithm gods
sharks don't float...
How are birds not even bird hipped dinosaurs? That makes NO sense.
The arrangement of the hips of the bird-hipped dinosaurs looked like those of birds, more so than most theropods and sauropods that were known when these names were given.
Derived theropods, like dromeosaurs, evolved a pubis that pointed backwards that more closely resembles the hips of modern birds. I talk about this more in my Deinonychus video.
i found it lol
What kind of views you get by copying bbc documentary videos.
Did you listen to the video or just look at the pictures?
