Teacher’s Chance Discovery Yields First Adult T. rex Footprints, Rewriting a Fossil Record Gap
A high school teacher’s chance discovery of two enormous footprints in North Dakota has led scientists to identify the first known adult Tyrannosaurus rex trackway, a find that fills a long-standing gap in the fossil record. The footprints, preserved in the Hell Creek Formation, offer rare clues about how the apex predator moved, how fast it walked, and how its behavior may have differed from earlier life stages.
