Male dinosaurs may have been prehistoric babysitters, study shows
Date:12/18/2008

he team examined three types of dinosaurs Troodon, Oviraptor and Citipati. If those names don't sound familiar, just picture the types of raptors that were chasing some of the people in the lab rooms in the movie Jurassic Park, he explains. Those types were also closely related to birds.

Moore says that the lack of any "cavities" (formed by the females when laying eggs) in the bones of the dinosaurs that were sitting on the eggs is a strong indicator that males, not females, were caring for the eggs.

"It's believed the females were focused strictly on the feeding and egg laying," Moore adds. "And more and more evidence points to the male as the egg caretaker. "The findings are surprising," he notes.

"If it's true that the males were principally focused on caring for the eggs, it leads to the question of what other species might have done the same thing? It raises other important questions about the behavorial characteristics of males in other species."
