Fossilized T. Rex Footprints Reveal a Human Walking Pace

Researchers analyzing the first known series of adult Tyrannosaurus rex footprints have determined the extinct apex predator moved at an ambling pace of 1.6 meters per second, according to findings published by Science News on September 23, 2026. That movement speed translates roughly to a quick walking pace for a human.

While the fossilized trackways were poorly preserved, the stride impressions provided enough data for scientists to calculate the dinosaur’s locomotion rate. The new discovery offers direct physical evidence of how the massive carnivore moved across prehistoric landscapes during normal travel, rather than relying solely on anatomical modeling or computer simulations.

Fossil Trackway Analysis

The physical condition of the steps presented challenges for the research team due to poor preservation, yet the stride geometry remained clear enough to measure velocity. At 1.6 meters per second, an adult Tyrannosaurus rex maintained a steady, measured gait rather than rushing, matching the speed of a brisk human walk.

Such trackways are exceptionally rare in the fossil record, especially for large carnivorous dinosaurs whose heavy footprints were often destroyed by environmental erosion or trampled by subsequent prehistoric fauna.

Locomotion and Speed Context

Previous biomechanical studies have debated how fast tyrannosaurids could travel, with estimates varying widely based on skeletal reconstruction and muscle mass calculations. The newly documented footprint series grounds those theoretical debates in empirical trace fossils, giving paleontologists a verified benchmark for standard adult movement.

Future paleontological field work in the region may uncover additional trackways to verify whether this 1.6 meters per second speed represented a typical cruising gait or an isolated instance of travel.
