Dinosaurs roamed at Government Canyon SNA

Special from TPWD

There they are, bigger than life - the only known dinosaur footprints on public land in Bexar County! The evidence is set in stone within Government Canyon State Natural Area. The 110-million-year-old tracks are believed to have been left by Acrocanthosaurus and Sauroposeidon dinosaurs.
Texas Parks and Wildlife and the Witte Museum in San Antonio have formed a new partnership to develop and provide interpretation, tours and exhibits about the tracks, as well as devise methods of conservation and protection for them. The public will be able to see the tracks either by visiting the Witte's new dinosaur exhibit or by hiking to the dinosaur track location inside the state natural area.
Acrocanthosaurus was a large theropod (carnivorous, bipedal dinosaur) up to 40 feet long and weighing 2 to 3 tons. Sauroposeidon was genus of sauropod, the large, four-legged, herbivorous dinosaurs with very long necks, small heads, and long tails. It reached sizes up to 100 feet long and 60 tons.
