DURHAM, N.C. (AP) — The 18-foot-long Parasaurolophus is friendly and patient, allowing children to climb its back, sit on its tail and pat its bumpy, coral-colored skin. But walk along the tree-lined path, and the evil 30-foot-long Albertosaurus lies in wait. The relative of Tyrannosaurus rex is ready to pounce — but will its next meal be the meat of the Edmontonia, with its head down as it tries to protect itself, or the young Styracosaurus across the path that seems to have wandered away from its herd? The four are part of the recently completed dinosaur trail at the North Carolina Museum of Life and Science in Durham. The trail includes nine types of dinosaurs from the Late Cretaceous period, the last period before dinosaurs became extinct, 100 million to 65 million years ago. It’s also a period when dinosaurs roamed North Carolina, although none of those stalking the museum grounds lived here.
