A rather more speculative restoration of leaellynasaura, a dinosaurs from the temperate Australian forests of the early Cretaceous period. I took it upon myself to give the animal fur-like filaments, like those shown in Kulindadromeus, despite it being the only ornithician yet found to have evidence of such a coating, but with more examples of at least a partial coating on animals like Tianyulong and Psittacosaurs. The next thing I did was give the animal a separate set of winter and summer coats, expressed in modern animals like arctic hares, foxes, and in the more closely related rock ptarmigan. Winters in Australia 118 million years ago would've been quite rough, so perhaps a thicker, and better camouflaged coat of filaments would've evolved in Leaellynaura. But. there is no strong evidence to support such a claim, so I will call this mere speculation on my part.
