Researchers analyzing fossilized trackways conclude that Tyrannosaurus rex may have moved much more slowly than commonly depicted in popular media. The study estimates a typical walking speed of about 3.5 miles per hour (mph), based on the spacing and measurements of dinosaur footprints and how fast such a stride would require.

The reporting across outlets emphasizes the contrast between cinematic portrayals of T. rex as a fast-running predator and the evidence-based interpretation of a steadier pace. Both sources describe the findings as indicating a “leisurely stroll” rather than rapid pursuit. They do not dispute the general ability of large theropods to move, but focus on the specific speed implied by the trackway record and the method used to infer locomotion from footprints.

Overall, the outlets agree on the headline result—an estimated ~3.5 mph movement speed derived from track analysis—while framing it primarily as a challenge to the speed suggested by movies. Any broader implications for hunting strategy or behavior are presented indirectly through the discussion of speed rather than detailed further in the articles.
