Coelophysis was an early theropod that is thought to have lived in family groups and hunted in packs. Much of what is deduced of Coelophysis behavior is based on the hundreds of well-preserved skeletons found at Ghost Ranch, New Mexico. Coelophysis has recently been renamed "Rioarribasaurus," but some researchers believe that these are two different animals.
