There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

How could pterodactyls not be reptiles? I've never read evidence of them having feathers or any thermo-regulating abilities of mammals.
They have no living relatives, so a lot of guesswork. It takes energy to fly, so likely warm-blooded. There is also evidence of fur. I believe that they were in a class of their own; evolved from reptiles but neither reptile nor bird nor mammal.
