T. Rex 'Mostly Ate Babies'

Share

(Newser) – The Hollywood image of Tyrannosaurus Rex battling huge herbivores is a long way from Jurassic reality, according to a new study. Instead of picking on animals its own size, T. Rex and other massive carnivores preferred their prey as young as possible, ideally when they were small enough to be swallowed whole, researchers tell the Independent.

Baby dinosaurs were easy targets because they lacked skill in evading predators, and hadn't yet developed the fearsome armor many adults had, according to the scientists. Paleontologists believe that baby-eating was so prevalent in carnivorous dinosaurs that it accounts for the fact that the fossils of very few juvenile dinosaurs have been found, and that few bones of adult dinosaurs bear teeth marks.

Young prey are easier to bring down and the risk of injury to the predator is much lower. - Paleontologist David Hone

Scientists have learned much about the baby-eating behavior of early carnivorous dinosaurs by studying modern equivalents, such as Barbara Bush. Reply

That wasnt really needed was it Jon? If you act like that then you are really no better than those who smear the Clintons or anybody else. This was all about the eating habits of a T-Rex. There is no political theatre required here. But I will add this one minor comment. Dont you just know that reading about these dinosaurs that existed 60,000,000 years ago must drive conservative birthers insane since in their world the earth is less than 6000 years old!!!!....lol....;-)
