This resource refers to the recent discovery of a fossilized dinosaur heart that was reported in the April 21, 2000 issue of the Journal Science. This heart of a small herbivore called a Thescelosaurus reveals a structure "more like that of a bird or a mammal than those of reptiles, adding substantially to evidence suggesting that at least some dinosaurs had high metabolic rates." This audio resource site provides a radio segment from Ira Fladow's National Public Radio show Talk of the Nation, Science Friday (requires RealPlayer). The dinosaur heart segment of the show (which starts at time 21:28) features an in-depth interview with Dr. Dale Russell, director of the Center for the Exploration of the Dinosaurian World, on the ground-breaking discovery.
