Crawling sensation - From all fours to bipedal giants-and needing parents

Abstract

Dinosaur embryo fossils dating back to 190 million years ago, have been assigned to Massopondylus, a plant eating biped. However, the body form of the embryo suggests that it hatched as a quadruped, crawling on all fours as it developed into a biped. Its' lack of teeth suggests that it depended on the parents for food.
