190 Million Year Old Dinosaur Embyro

leprasmurf writes "Sci Tech Today is reporting that scientists have cracked open a 190-million-year-old egg to reveal the oldest known dinosaur embryo. Examination of the fetal skeleton suggests the hatchling would have required parental care to survive. This would be the earliest evidence of nurturant behavior, more than 100 million years earlier than previous examples." The University of Toronto has a release about this as well. From the article: "According to Reisz, what makes this discovery particularly significant is the ability to put the embryos into a growth series and work out for the first time how these animals grew from a tiny, 15 centimetre embryo into a five metre adult. 'This has never been done for a dinosaur. Only Massospondylus is represented by embryos as well as by numerous articulated skeletons of juveniles and adults. The results have major implications for our understanding of how these animals grew and evolved,' he says."

Let's just hurry up and let this thread get hijacked by the creationist haters.
