Fossils Illuminate Dinosaur Evolution in Eastern North America
Published:25 Aug.2021 Source:Yale University
Tyrannosaurus rex, the fearsome predator that once roamed what is now western North America, appears to have had an East Coast cousin.
A new study by Yale undergraduate Chase Doran Brownstein describes two dinosaurs that inhabited Appalachia -- a once isolated land mass that today composes much of the eastern United States -- about 85 million years ago: an herbivorous duck-billed hadrosaur and a carnivorous tyrannosaur. The findings were published Aug. 25 in the journal Royal Society Open Science.
