Teacher Discovers Rare T. Rex Footprints in North Dakota Badlands

A high school teacher leading a summer fossil dig in the badlands of North Dakota has made a remarkable discovery: a series of four giant footprints that scientists believe could be the first trackway ever found belonging to an adult Tyrannosaurus rex. The find, unearthed on September 12, 2026, dates back approximately 66.5 million years to the late Cretaceous period, offering a rare glimpse into the locomotion and behavior of the apex predator.

The footprints were discovered by geology teacher Kirk Johnson, who was guiding a group of students near Bowman, North Dakota, when he stumbled upon the distinct impressions in the mudstone. Initial analysis by paleontologists suggests the size and spacing of the prints are consistent with those of a large, adult T. rex. Unlike isolated footprints, a trackway provides a sequence of steps, allowing researchers to infer gait, speed, and direction.

“Finding a single T. rex footprint is exciting, but finding a series that shows how it moved is extraordinary,” said Dr. Anya Sharma, a paleontologist at the University of Chicago who is consulting on the find. “This trackway could provide unprecedented data on the biomechanics of an adult T. rex, potentially revealing how it walked, hunted, and navigated its environment. We’re talking about a creature that was around 40 feet long and weighed several tons.”

Behavioral Insights and Context

The discovery is particularly significant because trackways from adult tyrannosaurs are exceedingly rare. Most known T. rex fossils are isolated bones or teeth, and while footprints have been found, a clear sequence from a mature individual has eluded scientists until now. The Tyrannosaurus rex, a name meaning "tyrant lizard king," was one of the largest land carnivores of all time. Its imposing presence dominated the North American continent at the end of the dinosaur age.

Previous research has often relied on skeletal structures to infer how T. rex moved, with some debate about whether it walked upright or maintained a more horizontal posture. The detailed impressions from this North Dakota find, including the depth and stride length, could help resolve these questions. The prints themselves are remarkably well-preserved, measuring over a meter in length, and appear to show the distinct three-toed structure characteristic of theropod dinosaurs.

The area where the trackway was found is known for its rich fossil deposits, part of the Hell Creek Formation, which has yielded numerous significant dinosaur discoveries over the decades, including a nearly complete T. rex skeleton in 1990. Johnson’s discovery highlights the ongoing potential for new finds even in well-explored regions. He and his students are working with paleontologists to meticulously document and excavate the site.

The implications of this find extend beyond just understanding T. rex anatomy. It offers a direct window into the last days of the dinosaurs, just before the mass extinction event that occurred approximately 66 million years ago. Studying the environment in which these prints were made could reveal more about the ecosystem T. rex inhabited, its prey, and its competition. The North Dakota badlands continue to be a treasure trove for paleontological research, underscoring the importance of preserving these natural laboratories for future scientific exploration.

Further analysis will involve detailed measurements, comparisons with other known dinosaur trackways, and potentially even attempting to identify the substrate conditions under which the prints were formed. This discovery promises to be a significant contribution to our understanding of prehistoric life and the majestic, fearsome dinosaur that has captured the human imagination for generations. Scientists are hopeful that additional discoveries await in the Hell Creek Formation.
