"However, resurrecting a dinosaur is out of the question," he added, reminding that living birds are dinosaurs. Bringing a Jurassic animal into the present could therefore be a disaster, probably worse than what some movies have fictionally predicted. At the very least, such an animal -- if it wound up in the wild -- could wreck havoc on the existing ecosystem.
Paleontologist Martin Sander of the University of Bonn told Discovery News that he agrees with the conclusions of the new paper, and said the tissue results "are great, because no other dinosaur embryo this old has ever been studied histologically." (Histology is the study of microscopic tissue structures.)
David Evans, curator of vertebrate paleontology at the Royal Ontario Museum's Department of Natural History, echoed Sander's view.
"The early life history of most dinosaurs is poorly documented, and the fossil record of dinosaur embryos is particularly scant in the Triassic and Jurassic periods," Evans said.
He continued, "The study by Reisz and colleagues is certainly the most detailed analysis of embryonic histology and development in an early dinosaur, and it will serve as a baseline for future comparisons with other species, which will deepen our understanding of dinosaur growth and evolution."
