Paleontologists say they found heart of dinosaur in chest cavity of dinosaur’s fossil skeleton uncovered in South Dakota, and that organ was more like heart of bird or mammal than any known reptile; finding could profoundly change theories of dinosaur physiology and place of at least some of those creatures in evolutionary history of life; scientists describe heart as size of grapefruit, fossilized into reddish-brown stone 66 million years ago; Dr Dale A Russell of North Carolina Museum of Natural Sciences, announcing discovery, says evidence for four-chambered heart with single aorta strongly suggests that this and perhaps many other dinosaurs had higher metabolisms than other reptiles; says they may have been warmblooded instead of coldblooded, like other reptiles, and thus could have engaged in more sustained activity in foraging and fighting; findings strengthen hypothesis that some dinosaurs were ancesters of today’s birds, which are warmblooded; photo; map (M)
