First Adult T. rex Trackway Reveals 1-Meter Footprints in North Dakota
Scientists report the first known trackway of an adult Tyrannosaurus rex from North Dakota, a 7-meter-long site with four footprints about 1 meter long dating to around 66.5 million years ago. The find provides rare behavioral data from footprints (estimated walking speed ~3.3–4.5 mph) and complements bone records. Three footprints will be moved to the Denver Museum of Nature & Science for study, highlighting how trackways can illuminate behavior and gait in large dinosaurs.
