Hot-Blooded or Cold-Blooded?
Evidence presented on this site pertains to dinosaur physiology. After a quick review of what has transpired in the last few decades, the reader is asked to form an opinion on what dinosaurs were like. Were they sluggish and stupid as the old conventional wisdom said, or were they mammal or bird-like as in Jurassic Park? Or can we even be sure what they were like? After a few preliminary warnings and some definitions, links take the reader to evidence for and against endothermic or ectothermic dinosaurs. A third link takes the reader to a review of current hypotheses.
