Summary:
With their long necks and tails, sauropod dinosaurs -- famous as the Sinclair gasoline logo and Fred Flintstone's gravel pit tractor -- are easy to recognize, in part because they all seem to look alike. The largest animals known to have walked the earth, sauropods were common in North America during the middle of the dinosaur era but were thought to have been pushed to extinction by more specialized plant-eaters at the end of that era. New discoveries, however, are showing that one lineage of sauropods diversified at the end of the dinosaur era, University of Michigan paleontologist Jeffrey Wilson says.
