Fossilized dinosaur feces and vomit help scientists reconstruct the creatures’ rise

NEW YORK — Using fossilized feces and vomit samples from Poland, scientists have reconstructed how dinosaurs came to dominate the Earth millions of years ago. Since the study’s findings were limited to Polish fossils, Qvarnström said he’d like to see if their ideas hold steady against fossil records from around the world. It’s not uncommon for scientists to study ancient fecal matter to understand creatures of the past, said Emma Dunne, a paleobiologist at the University of Erlangen-Nuremberg. “But they hold so much delicate, fine information.” ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Science and Educational Media Group.
