Dinosaur tracks found by flood recovery volunteers

• The team found several trackways with at least 15 individual footprints etched into limestone from the Glen Rose Formation — a geological layer known for preserving ancient dinosaur activity.
• The tracks are roughly 110-115 million years old, and each footprint is around 18-20" long, according to Brown.

What they're saying: "The tracks that are unambiguously dinosaurs were left by meat-eating dinosaurs similar to Acrocanthosaurus, a roughly 35-foot-long bipedal carnivore," Brown tells Axios.

What's next: Brown and his team expect to return to the site in the future to document the tracks with maps and 3-D imaging.

"We also want to investigate other newly exposed tracks nearby, which might represent a large herbivorous sauropod dinosaur," Brown adds.
