First full-grown T. rex trackway uncovered in North Dakota badlands

Paleontologists document the first trackway of an adult Tyrannosaurus rex—a 23-foot sequence of four three-toed footprints in the North Dakota badlands dating to about 66.5 million years ago. The animal is inferred to have walked about 3.5–4.5 mph, and the find, discovered in 2025 on U.S. Forest Service land near Marmarth, was described in the Journal of Vertebrate Paleontology. Three of the four prints will be airlifted to the Denver Museum of Nature & Science for study, highlighting movement clues that bones alone can’t reveal and building on evidence that only two adult T. rex footprints had been confirmed previously.

Ancient T. rex Walk: North Dakota’s First Adult Trackway Revealed

Paleontologists in southwestern North Dakota have identified the first trackway of a full-grown Tyrannosaurus rex: four three-toed footprints spanning about 23 feet, indicating the animal walked at roughly 3.5–4.5 mph and dated to around 66.5 million years ago. The site was found in 2025 near Marmarth, with 3D scans confirming the tracks; three footprints will be airlifted to the Denver Museum of Nature & Science for analysis, providing rare behavioral insight into T. rex movement before the mass extinction.

North Dakota Unveils First Known Trackway of an Adult T. rex

Paleontologists report the first trackway of a full-grown T. rex: four three-toed footprints about 23 feet long found in North Dakota's badlands, dating to roughly 66.5 million years ago and suggesting a walking pace of 3.5–4.5 mph. The discovery, analyzed via 3D scans and published in the Journal of Vertebrate Paleontology, includes plans to airlift three prints to the Denver Museum of Nature & Science for further study, offering rare insight into T. rex locomotion.

Giant Tyrannosaurus rex trackway uncovered in North Dakota badlands

Paleontologists report the first trackway of a full-grown Tyrannosaurus rex—a 23-foot sequence formed by four three-toed footprints dating to about 66.5 million years ago in the North Dakota badlands—showing the predator walked at about 3.5 to 4.5 mph. Found in 2025 near Marmarth on U.S. Forest Service land, the prints were 3D-scanned and analyzed by Peter Falkingham; three footprints will be airlifted to the Denver Museum of Nature & Science. This discovery provides movement insights that were previously unavailable from isolated T. rex footprints.

First Adult T. rex Trackway Found in North Dakota Badlands

Paleontologists report the first known trackway of an adult Tyrannosaurus rex — four connected three-toed footprints about 23 feet long from the Hell Creek Formation in southwestern North Dakota, dating to roughly 66.5 million years ago. The spacing suggests the animal walked at about 3.5 to 4.5 mph, and the creature weighed more than seven tons. Found in 2025 near Marmarth by volunteer Kent Hups, the footprints were scanned in 3D and described in a paper in the Journal of Vertebrate Paleontology; three tracks will be airlifted to the Denver Museum for study. The site adds behavioral context to T. rex locomotion and complements earlier isolated footprints and the juvenile “Teen Rex” specimen found in 2022.

Tiny South African Coast Uncovers Southern Africa’s Youngest Cretaceous Dinosaur Tracks

At a small 40-by-5-meter outcrop in the Brenton Formation near Knysna, researchers found more than two dozen dinosaur tracks dating to about 132 million years ago, the youngest known in southern Africa and only the second Cretaceous track record for the Western Cape; the prints suggest theropods and possibly ornithopods or sauropods, indicating repeated dinosaur activity in a landscape that may have included river channels or sandy shores, with studies hindered by tidal exposure and post-eruption layers that obscure the record.

Texas Flood Uncovers 115-Million-Year-Old Acrocanthosaurus Tracks

Fifteen 115-million-year-old dinosaur tracks—likely Acrocanthosaurus—emerged in a creek bed in northwest Travis County, Texas, after severe floods and were found by volunteers cleaning debris. University of Texas at Austin researchers confirmed the find and plan 3D imaging to study whether the tracks were made by a single dinosaur or a group, while cleanup crews are guided to protect the fragile site.

Record-Breaking Dinosaur Tracksite Unveils Over 18,000 Footprints

The Carreras Pampa site in Bolivia, the largest dinosaur tracksite ever found, contains nearly 18,000 tracks from around 70 million years ago, offering unique insights into dinosaur behavior and preservation due to exceptional environmental conditions that captured footprints, tail marks, and swimming traces of theropods, making it a significant paleontological discovery.

"Colorado's Public Dinosaur Trackway: A Prehistoric Hiking Adventure"

The Grand Mesa, Uncompahge, and Gunnison National Forests have acquired 27 acres of land in Ouray County, Colorado, including a trackway featuring 134 fossilized dinosaur footprints left by a long-neck sauropod dinosaur over 150 million years ago. The acquisition aims to protect this valuable scientific resource and provide an opportunity for the public to connect with the distant past. The site, known as the West Gold Hill Dinosaur Tracksite, will be open to the public, accessible via the steep and rugged Silvershield trail, with plans to add signage and improve access. This adds to Colorado's collection of prehistoric sites, including the Picket Wire Canyonlands tracksite in southeast Colorado.
