The blood vessels of a 70-million-year-old Tyrannosaurus rex discovered in Montana are virtually the same as those of an ostrich, according to a landmark study published in today's issue of Science.

Scientists were able to make the connection after isolating the soft tissue found in a thighbone of the T.Rex. Normally, the soft tissue isn't recoverable from fossils.

Scientists believe the discovery could lead to a better understanding of the physiology of dinosaurs, such as their diet, age and sex. It is not known whether any DNA is recoverable.
