Dinosaur Feathers

[@balazsvarga1823]

The mammoth and elephant shows that for coats, one must consider the environment and size. Large animals will have less covering, unless they live in cold areas.

[@palaeo_channel]

Exactly my point.

[@aberrantartist]

This is one of the most comprehensive and well organized explanations of feathers on dinosaurs that I’ve seen, thank you so much for this

[@StanFalade]

"Feathers have always been associated with birds, but they have also been associated with dinosaurs." So basically just "Feathers have always been synonymous with dinosaurs, but they have also been associated with dinosaurs."

[@ominous-omnipresent-they]

I personally would have gone with "Feathers have always been associated with both avian and non-avian dinosaurs."

[@fretnesbutke3233]

I have to praise Robert Bakker when this subject comes up. His book,The Dinosaur Heresies was published in the late 1970s,and was met with a lot of resistance. Years after being one of the first to suggest that birds are dinosaurs and that some dinos were warm blooded,that treasure trove of feathered dinosaurs from China was discovered,and that clinched it. There was a time when it wasn't taken for granted,and would have been met with derision by most paleontologists.

[@palaeo_channel]

I agree about The Dinosaur Heresies. Robert Bakker worked hard to get his pioneering ideas out there while many in the scientific community were against him. Time is a very effective filter, and warm-blooded, feathered, bird-related dinosaur have held up.

[@northropi2027]

Ooooo placing Sciurumimus as a non-coelurosaur is gonna turn some heads. Granted, either way, they'd have to debunk the apparent quill knobs but-maybe-nots on Concavenator, which I'm surprised didn't come up.

[@palaeo_channel]

Sciurumimus has been a dubious coelurosaur since 2019, and a 2020 study keeps it as a non-coelurosaur. But I was mainly going off Benton's work on feathers that agreed with the placement. Concavenator's 'quill knobs' are thoroughly inconclusive. I would have to spend a while explaining that, and news could come out making it irrelevant. I would go into it in a Concavenator profile, but did not feel justified for an overview.

Fascinating, and the animations you used are great!

[@Deadpool3E]

9:51 So there's a slight issue with this. It's not that these dinosaurs come from different localities that was the cause for feather loss - it's that feathers was a basal condition for Tyrannosauroids. T. rex and it's closest relatives we're derived animals that had also increased to greater body sizes and lived in hot climates where such covering was unnecessary. This would've affected other animals like Tarbosaurus and Alioramini tyrants. Yutyrannus and it's ilk we're still basal animals of relatively smaller size, with Yutyrannus still having feathers due to its climate.

[@pooyanshafai7566]

I don't know much about dinosaurs. But the feathered look makes much more sense than the scales for raptors. Shap of their legs and hand with a feather make complete sense given their close relationship with modern birds. But the classic cinematic look with scales looked like a strange monitor lizard standing on two feet. Thank you for your exelent video.

[@miguelpedraentomology6080]

wish you mentioned tupandactylus emu like pennaceous feathers and concavenator wings.

[@palaeo_channel]

While I am not a pterosaur expert, it seems that tupandactylus had fuzz like many other pterosaurs rather than pennaceous feathers, which were confined to theropods as far as my research went. Concavenator might have had feathers on it arms, or just tendon marks. The jury is still out on that, and I did not feel right placing it anywhere when it is so undecided. I would talk about it in a Concavenator profile, though.

[@miguelpedraentomology6080]

@@palaeo_channel pterosaurs are known to have various types of feathers just like the ones seen in birds, exemples are monofilaments, bristles, filoplumes and a inbetween of down feather and these mentioned. however a new fossil of tupandactylus imperator was found with really good preservation, specially integument, it not only has the tegument preserved by itself, but also melanosomes, showing that they were covered in brown and had orange in the tip of its crest. these feathers are not filoplumes or bristles, but countour pennaceous feather which are exactly like these of emus, albeit a bit smaller. such developed feathers were never found on pterosaurs before, and thus this new finding is quite revolutionary. about concavenator muscle attachment theory, there isnt much to say, it was proposed because the person found it weird about their position to be like that, so they proposed it, however they werent aware that various birds have them like that (exemple moorhens. it doesnt hold much ground nor does it have much into it, it doesnt even fit the description of any known attachment point or anything really, but theres still a chance its not quill knobs if some novel shait apears, but i wouldnt put much hope into it.

[@palaeo_channel]

@@miguelpedraentomology6080 Pterosaurs seem to be something that you know about more than I do. A lot of my video is based on 2019 data, and some things are going to be out of date, particularly the pterosaur information which I do not keep up with as much. Regarding the Concavenator issue, I am going with a 2022 paper by 11 palaeontologists that say that there is a possibility of feathers on the arms, but that there are other hypotheses for the evidence present: docentes.fct.unl.pt/sites/default/files/omateus/files/hendrickxetal.2021.morphologyanddistributionofscales.pdf

If one of these mutations happens to help, or even just not harm the life form, that one will survive to reproduce again, passing on its traits. Layer these random mutations and not so random survivals on top of one another for millions of years, and you'll end up with an entirely different species.
