Tyrannosaurus Rex Was A Chick

A North Carolina State University team of Scientists led by Mary H. Schweitzer has been studying the fossilized bones of a Tyrannosaurus rex, which was found in Montana. The team has found evidence that the T-Rex was not only a female, but an ancestor of birds as well. Medullary bone was found inside the leg bones of the creature. This is a layer of bone that forms in birds as they lay eggs. It aids the development of eggshells by supplying calcium. "The discovery of medullary bone in a specimen of T. rex is hugely exciting," said Chris Dacke of the University of Portsmouth in England. "It has never previously been reported in any other class of animal than birds." Sun-Sentinel latest ebusiness news
