LOL Dinosaur Dung Shows Eating Habits By MALCOLM RITTER .c The Associated Press NEW YORK (AP) - Scientists have found a piece of dinosaur dung as big as a jumbo loaf of bread, and it contains what may be the first direct evidence that Tyrannosaurus rex chomped the bones of its prey to pieces instead of gulping them down in big chunks. The 65-million-year-old lump is apparently the biggest fecal fossil known from a meat-eater. It was found in southwestern Saskatchewan, Canada, and because of its size, scientists think it came from a T. rex. The whitish-gray mass is littered with bone fragments from a juvenile dinosaur. Up to now, there had been no sign that T. rex and its two-legged cousins mashed up bones before swallowing, said Thomas Holtz Jr., a dinosaur expert from the University of Maryland who was not involved in the study. Instead, he said, most scientists suspected the meat-eaters either avoided bone or tore off huge chunks of their prey and simply swallowed whatever bone chunks came with it. T. rex couldn't chew as people do because its upper and lower teeth didn't meet each other. But those powerful banana-like teeth might have still pulverized bone as they sheared past each other, said Gregory Erickson of Stanford University, one of the scientists reporting the find. The fossil, some 17 inches long, 5 inches high and 6 inches wide, was found sticking out of a hillside in 1995 near the town of Eastend. ''It doesn't look like your typical dog doo-doo on the side of the road,'' said Timothy Tokaryk, supervisor of the Eastend Fossil Research Station. He and other scientists describe the find in Thursday's issue of the journal Nature. Dung fossils are called coprolites. They have been found on every continent, but few have been linked to dinosaurs with any confidence. The new specimen is more than twice as big as any previously reported coprolite from a meat-eating animal, the researchers said. AP-NY-06-17-98 1718EDT
