First adult T. rex footprints discovered in North Dakota
Scientists find a 23-foot trackway of four fossilized footprints dating to 66.5 million years ago in Hell Creek Formation.
What to know
- Scientists found the first known series of footprints from an adult T. rex—a 23-foot trackway with four three-toed prints dating to 66.5 million years ago in Hell Creek Formation, North Dakota.
- The trackway reveals the dinosaur walked at 3.5–4.5 mph (brisk human walking pace), calculated from 3-foot footprints spaced 13 feet apart.
- Trackways provide rare behavioral snapshots that isolated bones cannot; this is the first such T. rex sequence ever documented.
- Three footprints will be recovered by helicopter later in 2026 and housed at the Denver Museum.
“As a teacher, I'm always telling my students that science starts with curiosity, passion and careful observation. I never imagined that could lead me to a discovery like this.”

Three footprints scheduled for helicopter recovery
Three of the discovered footprints are set to be recovered by helicopter later in 2026 and transported to the Denver Museum of Nature and Science.
“Bones tell us an enormous amount about these animals, but footprints capture a moment of behavior.”

Researchers have confirmed the first ever sequence of footprints, or trackway, left by an adult T. rex, a discovery that offers rare insight into how the predator actually moved. The 23 foot trackway, made up of four three toed footprints roughly three feet long each, was…

Findings published; T. rex walked at brisk human pace
The research team's findings were published in a scientific journal. Using high-resolution 3D surface scanning, they determined each footprint was about 3 feet long with a 13-foot stride, indicating the animal walked at approximately 3.5–4.5 mph.
“With a trackway, we can actually follow an animal as it moved across the landscape. That is incredibly rare for T rex.”
