This was a pretty massive discovery. Dinosaur footprints were discovered in a Texas county after flooding washed away rocks and dirt that had buried them. A group of volunteers helping with flood relief efforts discovered the dinosaur footprints in Northwest Travis County shortly after a flood swept away large amounts of sediment in the region. ABC News reported more details on the discovery: Ancient dinosaur footprints dating back 115 million years were discovered in Northwest Travis County, Texas, after recent flooding swept away layers of sediment and brush that had long hidden them, according to officials. The discovery was made in the Big Sandy Creek area over the weekend by a group of volunteers, Travis County Judge Andy Brown, who serves as the county’s chief executive, told ABC News. The tracks were found on private property, with the exact location being kept secret at the owner’s request. University of Texas paleontologists confirmed at least 15 individual footprints, Matthew Brown, a paleontologist at UT Austin, told ABC News. Each footprint measured approximately 18-20 inches long and dated back 110-115 million years, according to Brown. The tracks were left by meat-eating dinosaurs similar to an Acrocanthosaurus, a roughly 35-foot-long bipedal carnivore, Brown said. Additional prints found nearby might have represented a large herbivorous sauropod dinosaur called Paluxysaurus, which is the official state dinosaur of Texas. Brown and fellow UT Austin paleontologist Kenneth Bader on Tuesday afternoon visited the spot where the tracks were discovered to assess them and to advise officials on protecting them during ongoing flood cleanup efforts. “We expect to return to the site in the near future to more thoroughly document the tracks with maps and 3D imaging,” Brown said. He said his team hoped to determine whether multiple dinosaurs moved together as a group or if individuals crossed the area independently. Take a look: Last month’s devastating Central Texas floods swept away sediment and brush, revealing ancient dinosaur footprints from 115 million years ago which were discovered last week. Their documentation will not disrupt ongoing cleanup efforts. pic.twitter.com/vkmOuHakr1 — Houston City Beat (@houstoncitybeat) August 11, 2025 Local 12 reported on the shocking discovery too: A trail of massive footprints left millions of years ago were discovered after floodwaters subsided following a devastating disaster. While helping victims of the extreme floods that tore through central Texas in July, a volunteer made a discovery of something left behind millions of years ago – dinosaur footprints. Experts who analyzed the tracks determined they were authentic, and likely came from Acrocanthosaurus, a large bipedal predator. Although technically different, the creature looks similar to a Tyrannosaurus-Rex. Researchers estimated the tracks were between 110 million and 115 million years old, and that they had only been uncovered due to the floodwater washing away the dirt and gravel that were covering them. In 2022, dinosaur footprints were discovered in Texas at a dried-up riverbed. Take a look: Massive dinosaur tracks have been uncovered in a dried-up river bed amid a historic drought in Texas. Experts say the tracks belonged to a 60-foot, 44-ton dinosaur called the Sauroposeidon around 113 million years ago. : Dinosaur Valley State Park pic.twitter.com/ScAcZ60nYI — WIRED (@WIRED) August 23, 2022
