First known T. rex trackway discovered in North Dakota's Hell Creek Formation

Researchers identified the first known series of footprints from an adult Tyrannosaurus rex in North Dakota's Hell Creek Formation, a 23-foot trackway of four three-toed prints. The discovery, made by teams from Denver Museum of Nature and Science and Liverpool John Moores University, provides direct evidence of T. rex locomotion and behavior, filling a gap in the fossil record. The find is significant for paleontology but has no immediate market or geopolitical implications.
