Against a backdrop of costly flood damage, Texas volunteers uncovered 115-million-year-old dinosaur footprints.

Story Highlights

Volunteers cleaning Central Texas flood debris found multiple dinosaur trackways near Sandy Creek/Big Sandy Creek.
UT Austin paleontologists confirmed authentic Early Cretaceous tracks, about 110–115 million years old.
Three-toed theropod prints (~18–20 inches) likely came from an Acrocanthosaurus-like predator; large round impressions may be sauropod.
Researchers plan rapid mapping and 3D imaging as attention grows and site risks increase.

Community Recovery Effort Reveals Ancient Trackways

Volunteers clearing debris after the early July 2025 Central Texas floods discovered several dinosaur trackways in limestone along the Sandy Creek/Big Sandy Creek area west of Austin. Floodwaters scoured sediment and brush from Glen Rose Formation outcrops, exposing three-toed impressions and larger circular prints embedded in the creek bed. The footprint exposures occurred during post-flood cleanups, when residents and helpers moved through damaged areas to restore access, identify hazards, and remove downed material obstructing recovery.

University of Texas at Austin paleontologists visited the site and confirmed the tracks as authentic dinosaur footprints. Specialists identified multiple prints as theropods, with individual tracks measuring roughly 18–20 inches long—sizes consistent with a large, meat‑eating predator. Additional large, round impressions nearby may represent sauropod activity. The researchers emphasized that catastrophic events can both preserve and reveal fossils, especially where carbonate muds of the Glen Rose Formation hardened into durable limestone now exposed along creeks.

Scientific Identification and What It Means

According to Dr. Matthew Brown, a paleontologist at the University of Texas at Austin, the three-toed dinosaur footprints are consistent with those of a large carnivore similar to Acrocanthosaurus, a roughly 35-foot predator known from the Early Cretaceous of Central Texas. While track fossils rarely allow definitive species assignments, the size and morphology match established patterns from Central Texas sites. The larger circular impressions could belong to a Paluxysaurus‑like sauropod, though researchers remain cautious pending full documentation. The age window—approximately 110–115 million years—aligns with Glen Rose exposures that have produced famous trackways at other Texas localities.

Teams plan to return for mapping and 3D imaging to capture accurate measurements, stride lengths, and trackway orientations before weathering, traffic, or vandalism degrade surfaces. Rapid documentation supports scientific analysis of gait, speed, and behavior, while enabling public education through digital models. UT Austin researchers and local officials note that with news spreading quickly, site managers will need to balance public interest with preservation, especially given the unstable conditions of post-flood streambeds. Coordinated stewardship can safeguard both research value and community safety as reconstruction proceeds.

Risk, Stewardship, and Local Control

Public attention raises immediate risks: erosion can erase prints, and unregulated visitation can damage fragile surfaces. Clear communication from local authorities and land managers can deter disturbances and direct interested visitors toward safe, legal access points or virtual exhibits. The discovery underscores the value of community‑science partnerships: residents on the front lines of recovery often notice what institutions miss, and their vigilance can trigger rapid expert response, documentation, and long‑term preservation strategies.

Central Texans are rebuilding after destructive floods, yet their volunteer effort yielded a scientific bright spot that belongs to the whole community. If managed well, the trackways could bolster local schools, museums, and geotourism, while teaching practical lessons about land, water, and heritage. Continued collaboration between volunteers, UT scientists, and local officials can protect the site, advance research, and ensure that future generations—Texans first—learn from a rare window into life on this land long before there were borders, highways, or power lines.
