My fursona, I had the mood to draw Iki in a realistic style and they're a fictional species but I designed them in a way they could be real.

Their species has boney/ceratin crests like many modern dinosaurs (birds) and like other past dinosaurs, for example Allosaurus and Dilophosaurus.
They have lips so protect their teeth (the black lip part is very mammal-like but I really like that so I draw them on my dinosaurs. Very spekulative but not unreasonable, I think.)
Their species feed mainly on fruits, vegetables and eggs, but occasionally hunt smaller animals too.
They aren't very big and have some bigger carnivores to fear, so they are quite shy.
Favourite habitat are cooler climates, landscapes with some trees and forests.
