Aren't all reptiles cold blooded?
If thats the classification for reptile, than I guess they aren't.
But I really don't konw.

 

The only exception for a reptile to be warm-blooded is to be a "mammal-like reptile" or therapsid. I'm not sure if therapsids possessed fur with reptile-like scaly skin, or had softer skin and no fur. If you look very close at human skin, you can see bare and soft scales, a remnant of our synapsid ancestors.

I think dinosaurs were both warm and cold-blooded depending on how far you go back in their evolution/lineage. Reply
