Dec. 4—WINONA, Minn. — It was a dinosaur that once roamed the earth 66 million years ago, and now a big piece of its sits housed in a lab at Winona State University in one of the rarest and largest fossil discoveries in recent memory.
It was called Edmontosaurus. And the duck-billed dinosaur was really big. From the tip of its snout to the end of its tail, it was as big as a city bus. And it lived alongside its contemporaries Tyrannosaurus Rex and Triceratops and existed just before all the large dinosaurs were wiped out in a mass extinction.
