Dinosaurs

Because scientists are studying fossils from many millions of years ago, rather than living animals, they usually cannot tell much about the dinosaur's habitat. They do, however, suspect that none of them lived in the water. Although a few dinosaurs may have been able to keep their bodies afloat for brief periods, or could wade to catch fish, none were full-time swimmers. Some scientists believe that sauropod dinosaurs may have been able to float and, based on footprints left behind, think they pushed themselves along by bouncing their front feet on the bottom of the pond or lake.
