dinosaurs evolved from reptiles and had 4 chambers and then they evolved into birds who also have 4 chambers.so they should be given a class.

ya and those early reptiles became mammals as well and plesiosaurs and pliosaurs and pterodans. A branch of dinos became birds and a branch of mammals went back to the sea and became whales, anyone want a continuing lecture in evolution?

In this book I read (The Ultimate Book of Dinosaurs), it said something about baby T-rex's might have had a shaggy coat of feathers-- similar to the rescent fossil finds in China...
Now, me, imagining a fluffy baby Rex is something I like to Laugh Out Loud at..., its something that really crushes the "macho-mighty-Trex" image that most of us have been bought up with...
I think that Raptors may have had feathers, and its likely that the Compys did eventually evolve to Archeoptryx... (similar skeletons)...,
but now, a T-rex... good grief, thats somthing that I can't quite believe...
