Dino Dung

A 65-million-year-old lump found sticking out of a Saskatchewan, Canada, hillside is the biggest fecal fossil from a meat-eater, scientists say. The dinosaur dung, about as big as a jumbo loaf of bread, may be the first direct evidence that Tyrannosaurus rex chomped its prey instead of gulping it down in big chunks. The whitish-gray mass, technically called a coprolite, is littered with bone fragments from a juvenile dinosaur. 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. The new specimen is more than twice as big as any previously reported coprolite from a meat-eating animal, the researchers said.
