schrafinator who where you talking to?
and compmage sorry about the Modern Book comment.
But in Walking with Dinosaurs there was leanosaurus(think thats the spelling) and Dwarf Allosaurus that they mentioned lived in the Cool climate.
Also Warm bloodedness is not the Only Reason they are seperating Dinosaurs from Reptiles. there are too Many differences that don't fit the Common Reptile features. 3 toes (I think is one of them) etc...
birds seem to fit very well with this Group and the Reason they can be considered Dinosaurs is Becouse they haven't had Much time to seperate from them (only 65 million years when dionsaurs ruled for 160) where as Mammals have had MUCH longer to Seperate from there Ancesters (Mammals Evolved the same time the first Dinosaurs did)
Mammal like reptiles(soon to have a another name.)Don't fit with Reptiles either. they think that these 2 Groups where Warm Blooded which would mean that Warm blood just Didn't happen when true Mammals and Birds came. Alot of things in the Dinosaur and Mammal like reptile Bones show Features in them that Only Warm Blooded animals seem to have.
