US archaeologists unearth first footprints of running T-Rex: ‘Incredibly rare’
Scientists have uncovered a rare sequence of fossilized footprints left by an adult Tyrannosaurus rex in the badlands of western North Dakota. Dating back roughly 66.5 million years, the trace fossils preserve a quiet moment of movement across an ancient terrain. This discovery allows researchers to examine how the apex predator traveled through its environment, offering behavioral insights that fossilized bones alone cannot provide. Footprint trackways function as trace fossils, capturing active creature behavior rather than physical remains.

T. rex Trackway Uncovered in North Dakota Badlands
Scientists have uncovered a rare sequence of fossilized footprints left by an adult Tyrannosaurus rex in the badlands of western North Dakota. Dating back roughly 66.5 million years, the trace fossils preserve a quiet moment of movement across an ancient terrain. This discovery allows researchers to examine how the apex predator traveled through its environment, offering behavioral insights that fossilized bones alone cannot provide. Footprint trackways function as trace fossils, capturing active creature behavior rather than physical remains.
Why it matters
Trace fossils provide direct evidence of prehistoric animal behavior and movement across ancient environments. While dinosaur bones offer structural details, preserved trackways reveal locomotion speed, stride length, and posture. Discoveries of this nature help paleontologists map out the daily movements of creatures that lived just prior to their eventual extinction.
What is confirmed
- A sequence of footprints from an adult Tyrannosaurus rex was discovered in the badlands of western North Dakota.
- The trackway dates back roughly 66.5 million years.
- Footprint fossils and trackways are categorized as trace fossils, which preserve creature behaviors or activities rather than the creature itself.
Still unconfirmed
- The trackway reveals a gentle pace of locomotion.
What to watch next
- Further scientific analysis of the western North Dakota trackway
- Publication of detailed stride measurements and movement data

US Archaeologists Unearth First Footprints of Running T-Rex
A Colorado high school teacher discovered the first known adult Tyrannosaurus rex trackway in North Dakota's Hell Creek Formation. The trail consists of four connected footprints dating back 66.5 million years, providing direct evidence of the apex predator's movement in a prehistoric swamp environment. Analysis indicates the adult dinosaur maintained an ambling pace of 1.6 meters per second with a 13-foot stride, moving at a speed comparable to a human walking briskly. The find offers rare clues about behavior and movement prior to extinction, showing details bones alone could never reveal.
Why it matters
The United States is a federal republic consisting of 50 states and a federal capital district, Washington, D.C. The discovery site in North Dakota falls under this sovereign jurisdiction, where federal and state frameworks govern scientific research and fossil recovery on public and private lands. Understanding the geographic and political makeup of the country helps frame how paleontological discoveries are managed and studied across different state territories.
What is confirmed
- The United States is a federal republic consisting of 50 states and a federal capital district, Washington, D.C.
- The United States has a population exceeding 341 million and ranks as the world's fourth-largest total area.
What to watch next
- Further academic publication or peer review regarding the North Dakota trackway
- Additional fossil discoveries within the Hell Creek Formation

First Adult T. Rex Trackway Discovered in North Dakota
A Colorado high school teacher discovered the first known adult Tyrannosaurus rex trackway in North Dakota's Hell Creek Formation. The trail consists of four connected footprints dating back 66.5 million years, providing direct evidence of the apex predator's movement in a prehistoric swamp environment. Analysis indicates the adult dinosaur maintained an ambling pace of 1.6 meters per second with a 13-foot stride, moving at a speed comparable to a human walking briskly. The find offers rare clues about behavior and movement prior to extinction, showing details bones alone could never reveal.
Why it matters
Kent Hups spotted the unusually large footprints during a morning research expedition in the fossil-rich sedimentary rock layers of the western United States. While the steps are poorly preserved, they yield critical data regarding the biomechanics and locomotion of large theropods. The discovery bridges a significant gap in paleontology by moving beyond skeletal remains to actual behavioral evidence.
What is confirmed
- A high school science teacher named Kent Hups discovered the first known adult Tyrannosaurus rex trackway in North Dakota.
- The trail consists of four connected footprints dating back 66.5 million years in the Hell Creek Formation.
- Analysis indicates an ambling pace of 1.6 meters per second, which is roughly equivalent to a quick human walking speed.
- The adult dinosaur moved with a 13-foot stride.
What to watch next
- Detailed academic publishing on the preservation state of the four footprints
- Further analysis of the Hell Creek Formation site by paleontologists

T. rex trackway discovered in North Dakota Hell Creek Formation
A high school science teacher discovered the first known Tyrannosaurus rex trackway in the Hell Creek Formation of North Dakota. The trail consists of four connected footprints dating back 66.5 million years. Analysis indicates the adult dinosaur had a 13-foot stride and moved at a speed comparable to a human walking briskly. Scientists describe the discovery as incredibly rare because it provides direct evidence of the predator's movement in a prehistoric swamp environment.
Why it matters
Direct evidence of T. rex locomotion is scarce in the fossil record. This find allows paleontologists to study the actual gait and speed of the species rather than relying on skeletal models.
What is confirmed
- A high school science teacher found the first known T. rex trackway in North Dakota.
- The footprints date back 66.5 million years.
- The trackway is located in the Hell Creek Formation.
What to watch next
- Further analysis of the stride to determine maximum running speeds
- Search for additional trackways within the Hell Creek Formation

First adult T. rex trackway discovered in North Dakota
Paleontologists found four connected footprints in the southwestern North Dakota badlands near Marmarth, marking the first known trackway of an adult Tyrannosaurus rex. A high school teacher discovered the trail while volunteering on a dig. The footprints date back roughly 66.5 million years to a period when the area was swampy. Analysis of the sequence shows the dinosaur had a 13-foot stride and moved at a speed similar to a human walking at a brisk pace. Scientists describe the find as incredibly rare.
Why it matters
Direct locomotion data for adult T. rex was previously unavailable. This sequence allows researchers to study the actual movement and gait of the predator in its natural environment.
What is confirmed
- The discovery consists of four connected footprints in the North Dakota badlands.
- The trackway dates to approximately 66.5 million years ago.
- A high school teacher found the trail while volunteering on a paleontological dig.
- The dinosaur had a 13-foot stride and traveled at a speed comparable to a human walking at a brisk pace.
What to watch next
- Peer review of the locomotion analysis
- Further excavation of the Marmarth site for additional tracks

Archaeologists discover first adult T. rex trackway in North Dakota
Archaeologists unearthed the first known adult Tyrannosaurus rex footprints in the North Dakota badlands. The discovery consists of a continuous trackway that provides the first direct locomotion data for an adult T. rex. Analysis reveals the dinosaur had a 13-foot stride and traveled at a speed comparable to a human walking at a brisk pace. A schoolteacher discovered the trail, which scientists describe as incredibly rare.
Why it matters
Most T. rex knowledge comes from skeletal remains rather than footprints. This trackway allows researchers to observe actual movement patterns rather than relying on computer models.
What is confirmed
- The first known adult T. rex footprints were found in North Dakota.
- The discovery is a continuous trackway of an adult Tyrannosaurus rex.
- A schoolteacher found the Tyrannosaurus trail.
Still unconfirmed
- The adult dinosaur had a 13-foot stride and moved as fast as a human walking at a brisk pace.
- The footprints are described as incredibly rare.
What to watch next
- Peer-reviewed publication of the locomotion data
