Many paleontologists believe there is strong fossil evidence that some types of dinosaurs moved in herds, bred in colonies, or cared for their young. All of these behaviors have been observed in living reptiles, says Gordon M. Burghardt, an ethologist at the University of Tennessee at Knoxville. For example, young green iguanas often move about in groups and sleep together, and crocodiles exhibit some parental care. However, there is no evidence that any modern reptile takes care of incapacitated adult kin, says Burghardt. --S. PERKINS
