La República (Peru)LO·1 day ago
Paleontologists have discovered the first known footprints of an adult Tyrannosaurus rex, dated to 66.5 million years ago. The trackway indicates a walking speed exceeding 6 km/h, providing new data on T. rex locomotion. This is a notable scientific first, though its broader significance is limited to paleontology.
