Sep. 12th, 2026 03:11 pmMassive Footprints Reveal First Ever Adult T Rex Trackway, a 66-Million-Year-old Walk Through North Dakota
The 23-foot-long trackway consists of four three-toed footprints discovered in the Hell Creek Formation. Each footprint is roughly 3 feet long, and researchers estimate they were made about 66.5 million years ago.
In findings published this week in the Journal of Vertebrate Paleontology, the team identified T. rex as the likely track-maker based on the footprints’ exceptional size and narrow shape of the toes, along with the abundance of T. rex fossils found in the surrounding area.
