Dinosaur embryos discovered nearly 20 years ago but excavated only last year suggest that the fully grown individuals of this species may have been doting parents.
Researchers at the University of Toronto looked for clues to dinosaur development in the fossilized eggs of a type of dinosaur that grew to ten feet in length. Extrapolating the growth of the embryos by referring to better-understood samples dating to the Cretaceous age, the probable development of members of this earlier species was surmised. Scientists theorize that the dinosaur neonates initially crawled on all fours and were dependent on their parents for survival. Only later in life did the rapid growth of these individuals allow them to achieve bipedal motion, researchers say.
