New Ostrich-Mimic Dinosaur Species Identified “We histologically thin-sectioned the femur of Rativates evadens to analyze its growth and determined it was at least eight years old and nearly adult-sized at the time of death,” said Thomas Cullen, from the University of Toronto. .... “This suggests that there are at least two differently-sized, but closely-related dinosaur species that lived together on the ancient landscape, similar to what we see today in the closely related predators like foxes, coyotes and wolves,” said Dr. Claudia Schröder-Adams, of Carleton University.
