Medical imaging shows dinosaur heart more like bird's or mammal's than reptile's
... Washington D.C. -- A computerized tomography (CT) scan
of the chest cavity of a new dinosaur fossil reveals a heart more closely resembling a bird or mammal organ, rather than a modern reptile's. This discovery, which suggests that the dinosaur was warm-blooded, with a relatively high metabolism, is repo...
