They may have developed mammary glands despite not being a mammal because it's a lot more efficient to feed babies that way rather than having to scrounge around in the desert for food. They don't have crops, either, so it'd be hard to digest it for small babies. #Aletar

They're kinda a mix between birds and reptiles, just like dinosaurs. XD

OHOHOHO these guys are so great. Really, all their concepts and designs and whatnot are fantastic.

Yes, that too. I've probably thought the skull through before I did this question in depth, so it is a bit weird for a dinosaur. XD Maybe they're more proto-mammals? Like partially reptilian?

I originally thought this pic was about whether birds are closer to mammals or to reptiles so that's why I made the textbook post.
