A neat follow-up could be the exact opposite idea which sprouted up in the 2010s: over-feathering dinosaurs which likely had little to no feathers in reality.

This mostly stems form the fact that most of the surviving modern reptiles are lepidosaurs, and many people assume things about dinosaurs based on their knowledge of modern reptiles. This caused beliefs like that being prevalent in the past and many people nowadays still perceive dinosaurs this way.

@lorencalfe6446 7 ай бұрын

Reptiles are a huge group, in fact if you extend the reptile moniker to ‘reptile-like’ terrestrial amniotes like westlothiana lizzie mammals would be reptiles too. The thing about taxonomy is you can include and exclude any ancestor to redraw the branches. In the big picture everything is universally monophyletic anyways. Anything else is artificial categorization.

@petersmythe6462 7 ай бұрын

It doesn't help that archosaurs which have survived are weird outliers. Birds are flighted while crocodiles are secondarily aquatic and secondarily coldblooded. Imagine trying to piece together the characteristics of mammals if your only surviving representatives were bats and marine sloths?

@stefanostokatlidis4861 7 ай бұрын

Scales are the default for all reptiles. Lepidosaur scales aren’t very different from other scales. Even birds have scales on their legs. Although most of their scales are derived from feathers, the reticular ones on the bottom of their feet are original. Other reptiles have secondary scales too, such as the head scales of crocodilians and the tubercles of softshell turtles.

@StelloTyrannus 7 ай бұрын

All dinosaurs had scales, some just had less than others, just look at a birds scaly feet. You could even count feathers themselves as modified scales, since that’s one of the thoughts behind their origin

I loved dinosaurs as a kid in the 80’s. I remember the first time one of the dinosaur books I got showed a Pterosaur with Picnofibres. I hated it. It just seemed wrong. Decades later when they started showing therapod dinosaurs with scruffy protofeathers I hated that too, it just didn’t ‘fit’, but as they have learned more and the representations have evolved I’ve grown to love it- the newer representations do ‘fit’, particularly the maniraptorans. I love the look of the feathered dinosaurs now! It makes me feel like we really are living amongst real dinosaurs today,… which of course, we are.

@minutemansam3122 7 ай бұрын

Pterosaurs had feathers, too. So it's likely that feathers are ancestral to Avemetatarsalia. So any dinosaurs without feathers are likely secondarily featherless. Evolving from feathered ancestors and subsequently losing feathers when they grew too large for feathers to provide benefit and started becoming harmful. Thanks to the square cubed law.

@@yissibiiyteit really hasn't. Most small dinosaurs likely has feathers for insulation, and we've discovered ornithischian dinosaurs that possessed feathers. It seems only the large genera lost their feathers, while smaller relatives retained them. Given that fossil skin impressions are very rare we cannot definitively say which groups lost feathers and when. There is even some evidence that certain large carcharodontosaurids has feathered offspring if many of the remains of juvenile 'compsognathids' were actually juvenile carcharodontosaurids.

A lot of people are forgetting that you don't really need feathers or scaly designs to make anyone *look* realistic, you need to understand anatomy and the relations of osteology and the musculatory system to the skin and overall outside appearance. Many pop culture dinosaurs aren't unrealistic strictly because they aren't feathered, but because they are mangled corpses (and I would know a lot about that lmao). Now when it comes to accuracy, then yeah, some need to be feathered, some need to be scaly, as well as follow the basic anatomical template of the species/genus based on how much we know about them. All in all, I just want people to stop drawing them like horrific monsters instead of sentient animals that they were and still are.

In fact, the first dinosaur with feathers detected was Avimimus. Kurzanow made this conclusion based there are small ridges on its forearm that could be anchor points for feather shafts. However, his theory did not gain scientific acceptance at that time because it was only 1987.

Personally, I think the argument that any late ornithischians didn't have any fiber coverings is biased. Those filaments wouldn't fossilize easily, even under ideal conditions. The argument that they were too large to need it once they got to the size of elephants due to internal heat regulation. It ignores the fact that *elephants have hair*! We've found basal ornithischians with 3 different types of coverings of feathers/filaments all on one animal. To say that we have Kulindadromeus, bristley quills on psittacosaurus and nothing in between or afterwards is crazy to me. It's the equivalent of finding the first fossil evidence of fur 80 Mya and a modern porcupine and saying there was no instance of fur between the two. Plus if the ornithoscelida theory is correct we might have to redo all of our reconstructions of that lineage. I love the idea of ornithischian lineage developing convergent coverings. Ceratopsids looking like wirey warthogs. Hadrosaurs looking like giant bison/water buffalo. Ankylosaurus with armadillo underbellies. Thank you for coming to my Ted talk! I can provide adorable pictures of fluffy triceratops if requested.

@catpoke9557 7 ай бұрын

Note that it is possible all or most scaly dinosaurs had elephant fuzz, but it's also possible that most or all scaly dinosaurs did NOT, because they didn't actually 'lose' their feathers like elephants lose their fur. Rather, their feathers just changed into a different form, that of scales. So they may have actually lost them altogether because it's not the same process. We don't know which is true and so it's up to the artist to decide.

@jrbaxterstockman548 7 ай бұрын

@catpoke9557 We don't know the real picture. But in Kulindadromeu, we saw 3 forms of feathers, *and scales* . As much as fluffy hadrosaur Buffalo's would be awesome, it would probably be a lot of scales and a little filament like certain theropods like yutyrannus at the most covered. We don't know the full picture. There's preservation biase, but the integument of derived ornithischians has shown only scales. That could be confirmed as the only type seen with more sample size. Or reality might be in the middle. Elephants have very sparce hair, and I bet it wouldn't hold up if the thing was mummified for 80-160 million years. But until we know for sure I am happy to take the outlier opinion. Let me hold onto my dream of fluffy baby hadrosaurs cuddling as they honk-chirp!

@jrbaxterstockman548 7 ай бұрын

@EDGEscience who knows, maybe they only had feather based eyelashes and males had brightly colored ones. There's a world of possibilities

@catpoke9557 7 ай бұрын

@@jrbaxterstockman548 Personally I think that large dinosaurs generally did lose their feathers entirely because of the fact it's a different process, but I really enjoy the idea that they didn't, so I still like to depict them with elephant fuzz sometimes just because it makes me happy. As for fluffy babies, that's possible either way considering that modern birds shed their baby fuzz into full pennaceous feathers. Considering dinosaur scales are actually all modified feathers, there's no reason why baby fuzz can't shed and turn into scales. So that, again, is entirely up to the artist! Also, I like the feather eyelash idea. Something we see often with animals is the loss of integument across MOST of the body, but still present in some areas. Like the whiskers of whales. Some scaly dinosaurs may have retained feathers in certain areas for functions other than insulation. Such as, yes, eyelashes. Or whiskers. I think I will actually take this idea of yours and incorporate it into my art. Feather eyelashes on scaly dinosaurs is a really interesting and plausible idea.
