Never really bought into that idea myself anyway...

I recently completed a project creating images for the West Hartford Children's Museum new dinosaur exhibit. The project involved about 20 small (2' x 3') images, and three 16 x 20 foot murals. You can see one of the murals in the image below. The mural depicts feathered dinosaurs (Yutyrannus, Psittacosaurus, Caudipteryx and Sinosauropteryx) to contrast with the model of Deinonychus that is not feathered to display the changing views of dinosaurs. Link to two stories about the opening of the exhibit with additional images.

Hey PaleoGuy, I have a question. Love your artwork and I've noticed a lot of Abelisaurs and Carnosaurs being rendered with the proto-fuzz found on a lot of Ceolurosaurs. I'm not arguing it, just curious if I miss an important discovery as I hadn't heard of them having feather. I do try to keep up to date but paleontology is a big field so occasionally I miss a few things. To my knowledge pretty much all epidermal impressions from those two groups showed either bare skin, scales, or even scutes.

On behalf of all paleoartists who reconstruct their non avian Dinosaurs as original, strange, beautiful, terrifying and unique as possible (while still being scientifically accurate), I'd like to thank you dearly for reconstructing not only a Carcharodontosaurid with feathers, but also an ABELISAUR with feathers. This is a rare site in paleoart  due to everyone not only copying off of everyone else, but also because people just automatically assume that since a couple of species are known from relatively small, damaged scale impressions, that all of their relatives were automatically completely devoid of anything else but scales. Thank you for being such a unique and original artist. May I add a few possible ideas that you could give to your Dinosaurs that would make them even more unique?

Not arguing with you, just curious as I hadn't heard anything about this. Did we find feathers on Abelisaurs yet? I had heard of some debatable evidence from a few Carnosaurs, but everything I'd heard from the former group was all scales. The extensive epidermal impressions from Carnotaurus were all bare skin, scales, and some scutes last I checked.

Technically speaking, we don't have direct evidence of feathers on Abelisaurs, let alone Ceratosaurs, but we do know that Theropoda as a whole has feathers ancestral to it/is a suprisingly common trait (although feathers are definitively ancestral to Avemetatarsalia-the ancestor to Dinosaurs and Pterosaurs-, so that makes it even more broad). Yes, we do have (somewhat) extensive avian scales* on Carnotaurus (and a little bit on Abelisaurus), but we only have it from patches from the upper body, legs, and upper neck of the animal, so it doesn't rule out the possibility of feathers on other areas of the body, arms or tail. You don't usually see feathers on Ceratosaurs in general in paleoart because many people often think that just because a single, highly derived species within a highly diverse, long lasting group of Theropod (aka the group of Dinosaurs we know without a doubt to be predominantly feathered) has some patches of avian scales*, that automatically every single species has to be completely scaley. It honestly doesn't make since to do that. And even though we have these scale inmpressions, it doesn't rule out the fact that feathers could still be prevelent on even these scaley areas. Many modern day Dinosaurs have (somewhat) specialized avian scales* that support large amounts of feather in the "chinks" between the scales themselves. This is most commonly found in owls, but can also be seen in chickens, pigeons, etc. There is also the possibility that many non avian Dinosaurs could have independantly evolved a similiar trait to what is commonly seen in Armadillos (especially screaming Armadillos) in that the fiborous integument actuallt grows on top of the scales:

I know that they are not anywhere near closely related, but the scales of Armadillos are oddly similiar to that of many non avian Dinosaurs (Abelisaurs, Thyreophorans, Ornithopods and many Sauropods come to mind).

On the matter of Carnosaur feathers, there is actually physical evidence that they had feathers. Concavenator has defintive proof of feathers through the appearance of quill knobs on the arms, which are also very common in many modern day birds. The knobs were once thought to have might have been muscle extensions, but these rumors/notions were primarily silenced at the SVP 2014 meeting due to a better in depth look. There is also possible evidence of even more basal Theropods that had feathers. Sciurumimus once though to be a Megalosaurid, but is now usually regarded as a basal Coelurosaur and/or Compsognathid (although since it's literally a hatchling, it's incredibly hard to tell where it actually fits cladistics wise), although there are mud impressions made by an early Jurassic relative of Dilophosaurus that shows traces of feathers where it was sitting. This is rather controversial though seeing as how it also possibly be ripels within the mud, but either way it would have had feathers due to our current understanding of phylogenetic bracketing alone. All of Coelurosauria is known to be highly "floofy" without a doubt though (including giants like Tyrannosaurus rex and the ilk).

*Avian scales aren't "true" reptilian scales, but are rather formed by feathers "condensing" (I don't have a better word to describe it) into hard, durable nail like shapes. They can also easily turn into scutes. This trait has also independantly evolved in Synapsids, but instead of feathers, it's hair.

Thank you for the extremely extensive and well made response, do love the visuals you included. I do apologize if my response is quite lackluster by comparison my friend :)

Though this all leads into a bit of a conundrum. Given we aren't quite sure when filament coating evolved in Archosaurs, a group who's exact origins is still a bit of a blur, and if we are to poise that the ancestor of dinosaurs was entirely coated in just filaments, thus all scales found in larger dinosaurs are avian scales; this does leave a big question. Had filament covering evolved in some still bare patch of the fossil record. Had the evolution of filaments occured before Crurotarsi split off from the lineage leading to dinosaurs and pterosaurs, then that means all crocodilian scales would technically could as 'avian scales'. Crocodilian scales are distinct from both Squamata and Testudines scales, the latter two having a different internal structure and are generally quite uniform where. This is opposed to crocodilian scales, which are much more varied make up and size, giving it a mosaic look actually quite similar to some dinosaur skin impressions (the back scutes withstanding). They actually have a closer morphological similarity to the avian scales on bird feet, but lack a proper terminology in the lexicon to distinguish them.

Basically it's a classic 'chicken or the egg' scenario. All avian feathers and filaments are derived from scales, but when do you stop calling it a scale and start calling it a feather and then start calling it a scale again when it turns back into a scale? If avian scales are unique to dinosaurs and their descendents, but crocodilians have similar structures, does this mean that at some point the ancient Suchia ancestors were also 'fuzzy'? Were all dinosaur scales derived from filaments or did they have multiple types of epidermal covering that just flip-flopped as to how expressed they were? Which came first, the Avemetatarsalia with scales or the Crurotarsi with fuzz?

*skin impression of a Tarbosaurus's thoracic region showed scale like patterns of multiple sizes, but its hard to tell if it had scutes amongst them given the find was damaged by poachers.

Have you ever thought of putting these in a book? Who has the copyright? Perhaps they could be persuaded to have a book brought to print. Great work.
