Scientists find oldest adult T. rex trackway

Scientists in North Dakota have discovered the first adult T. rex trackway, consisting of four connected, large three-toed footprints dating to approximately 66.5 million years ago. The trackway, measuring about 23 feet in length with toes around 3.3 feet long, provides rare behavioral insights and was made by a T. rex walking at roughly 3.5 to 4.5 mph. This finding, supported by skeletal evidence and modern 3D imaging, enhances understanding of T. rex movement shortly before the dinosaurs vanished.
