Otto by Eurwentala Otto by Eurwentala
A finished reconstruction of Otto the German baby theropod. The color was mostly inspired by baby ostriches.

More information about Otto in the lineart deviation: [link]


As a later addition: the species has now been named Sciurumimus albersdoerferi and confirmed to be a baby megalosauroid. It seems in reality it had ridiculously long tail feathers, not short ones like this picture.

Sadly sciurumimus was reclassified as a coelurosaur. There goes the possibility of feathered megalosaurus.

Well, the possibility hasn't gone anywhere, it's just that we don't have direct evidence now. Which is a shame. :) We do have multiple feathered ornitischians, though. So I think we have a fairly good justification for putting at least some filaments on any dinosaur now.

That is, if the structures on the ornitischians are homologous (which I personally doubt because they are rather quill-like)

Sure, it's in no way obvious they're homologous to feathers. I wouldn't be surprised if fuzz evolved separately multiple times - in pterosaurs, in ornitischians, in theropods, and perhaps somewhere else too. It seems to be fairly easy to evolve.

But have you seen the strctures of Kulindadromeus? It has soft, small, plumaceous structures that look a lot more like down feathers than quills.

I don't see why they couldn't have evolved independently. This issue could be settled once and for all if we find a Late Triassic dino with these structures.

Kulindadromeus has some structures that are rather unique such as the ribbon-like structures on the legs.

Yeah, they definitely could have evolved independently. Or not. We just don't know yet. :)

Finding a Late Triassic dino with preserved integument would sure help tremendously. I wonder if they could eventually find one in Madygen, the formation where Longisquama and Sharovipteryx were found.

Well I definitely learned something new today! Very cool picture; would love to see more artwork on Sciurumimus albersdoerferi. If you do decide to another version feel free to let me know :)

You're definitely a talented artist; love this picture except that Sciurumimus albersdoerferi did have a long feathers and it is believed to have ate insects. It wasn't until it matured into an adult Megalosaur that it is believed to have made the transition to meat-eater.

Thanks!
This was drawn before the critter got a formal description, and I already note in the description that the tail feathers are not accurate. I should draw it again with a proper squirrel tail at some point.

I think it has been pretty widely accepted that many dinosaurs took care of their young, at least for a while after hatching. A newly hatched Sciurumimus could not have hunted other dinosaurs by itself, but if it's mom did the killing, why not? Also, almost any generalist insectivore today will take advantage of a nice dead animal it happens across, so I'm fairly sure this would be considered normal behaviour in such a case too. I've seen pictures of great tits eating dead deer, for example.
