CHICAGO (AP) - Apparently, reckless adolescent behavior has been around a lot longer a lot longer than people realize. As a matterof fact, it's been around a lot longer than people.
University of Chicago paleontologist Paul Sereno says that's one of the lessons of some recent fossil finds in the desert regions of
China.
Sereno says a large group of adolescent and preadolescent dinosaurs died en masse 90 million years ago when they ran into a
mudhole, sinking to their doom.
Many of the 25 individuals recovered were so perfectly preserved that their last meals could be identified.
Sereno is scheduled to give a formal report Monday in the provincial capital of Inner Mongolia on the findings of the joint
U.S.-Chinese expedition that found the fossils.
