NEW YORK (AP) — Not all two-legged dinosaurs were like the lumbering Tyrannosaurus rex. An analysis of dinosaur tracks from 120 million years ago unearthed in Spain adds to growing evidence that these meat-eating prehistoric beasts belonging to the same group as T.rex could be highly agile. The findings, published Thursday in Scientific Reports, reveal one of the fastest known sets of fossilized dinosaur footprints. These tracks join the ranks of other speedy sets found in Utah and Texas, one of which shows dinosaurs running at speeds over 30 mph. Scientists think there may be other faster dinosaurs, but the tracks of theropods have been easier to track down.
