No, they were not. There were many other warm blooded species before them. I'm not sure of specific names, but I know that birds were along much longer than the dinosaurs, and birds are warm blooded.
Let me clarify from above. According to the currently accepted Evolution Theory, birds evolved from dinosaurs. Birds are warm blooded but dinosaurs, as far as the scientists can tell, were cold blooded.

∙ 9y agoA warm blooded animal is called an endotherm. So if dinosaurs were in fact warm blooded they were endotherms. If they were cold blooded, which seems unlikely given the evidence, they were ectotherms, and if they were in between the two, dinosaurs were mesotherms.
