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.
We believed that dinosaurs were reptile. But now they no longer are. Because, yes, reptiles are not hot blooded animals with feathers and so on. Otherwise we have to modify, to alter, the reptile definition.
I think Archaeopteryx was a first attempt from the dinosaur lineage in order to become a winged animal with feathers. But it wasn't a success.
