"Reel Around the Sky" and "Reel Around the Sun". I've had dromaeosaurs and ancient life on the brain something FIERCE lately. Coloration and patterning partially inspired by local hawks and the Carolina Wren.
Deinonychus and Suchomimus concept art sketches made in color pencil and outlined with a pen. I decided to go for a sexually-dimorphic take on the former, with the blue-gray/orange individuals representing the males and the brown-colored ones representing the females.
Another commission done, for Zapsalight on Twitter! My commissions are open.
BEHOLD: the drawing!
This is one of my favourite scenes from my story, Project TL, taking place circa around the beginning of book 2. Both characters were having a terrible week for extremely different reasons and this was the culmination of it!
Featured in the drawing are William (Liam, protagonist, the guy) having a bad not so good overall terrible day and Teryel (Teri, love interest, as a dino) using his Utahraptor form to improve the situation.
This scene. Is the reason. I have seven-ish books instead of two!
(scene description & fun facts below)
My 25 years of palaeoart chronology…
Zoom into my Wulong reconstruction, from 2021. This was the press release artwork for a paper describing "The iridescent plumage in a dromaeosaurid theropod dinosaur" (Croudace et al).
Would any dromaeosaurs have likely had bald heads like turkey vultures?
It's certainly possible, and I'd go so far as to say quite likely!
We do have some fossil evidence for dromaeosaurs with feathered heads:
Image sources: Tianyuraptor, Sinornithosaurus, Daurlong, Microraptor.
As for the rest though, we don't have a clear fossil of a bald-headed dromaeosaur! To be certain, we'd probably need to find specific impressions of naked skin around the head, which to my knowledge has not been found yet.
The feathered fossils above belong to either small (right side) or medium-sized (left side) dromaeosaurs, so it indicates that any dromaeosaurs up to a Velociraptor-type size certainly could have had feathered heads.
That being said, the level of head feathering is very variable in modern birds even within the same group. Some vultures have bald heads which may help with cleaning their faces and heat regulation, but there's much wider variation than you might expect! Even just within the clade Aegypiinae, we've got:
Image sources: hooded, griffon, red-headed, lappet-faced, white-headed, cinereous.
There's a whole range from nearly full plumage to fully naked skin folds to Justin Timberlake Ramen Hair, and I'd say there's no reason to think that dromaeosaurs and other feathered dinosaurs couldn't have had the same level of variation between species!
It's the kinda situation where in the absence of direct evidence, I'd consider varying levels of head baldness in dromaeosaurs as pretty reasonable speculation! So here's a Deinonychus decked out with a variety of different styles that are within the realms of possibility:
And that's not even taking into account that in a lot of bald-headed birds that skin space is prime real estate for all sorts of flippy flappy dangly bits and colours and lumps and bumps.
So basically, it's not like we can point at any particular dromaeosaurs and be like "that one probably had a bald head", but unless there's contrary evidence I feel it's very likely there was a lot of variation in how feathery the head was!
There is a dinosaur called Pyroraptor olympius - literally, "Fire thief of Mt. Olympus." So of course I had to draw Prometheus as one.
