The footprints of a dinosaur that rumbled through northwest Bexar County 110 million years ago will soon be on display in an interactive exhibition at the Witte Museum, Newsradio 1200 WOAI reports.
It's part of a special partnership between the Witte and the Texas Parks and Wildlife Department, which runs the Government Canyon State Natural Area off of Galm Road.
Dr. Thomas Adams, Curator of Paleontology for the Witte, says the hundreds of tracks were probably made by the dinosaurs Acrocanthosaurus and Sauraposeidon, and were made when South Texas was a very different place.
"So here we are in Government Canyon State Natural Area" he said. If we were standing here 110 million years ago, if we looked toward the southeast, toward what is now San Antonio, we would be looking at the Gulf of Mexico. Most of the homes in San Antonio would have been underwater.
He says the dinosaurs made the tracks between what is Government Canyon today was essentially a limestone beach, separating the sea from the impenetrable woodland in what is now the Hill Country.
Adams says we would not like to have come across the carnivorous dinosaurs who made the footprints.
"This would have been an animal that was close to 40 feet long, weighed two to three tons, almost as big as T. Rex but not related to T. Rex. And here it was in San Antonio, walking along the beach.
In fact, the tracks were preserved because the dinosaur was walking along the soft limestone which, more than 100 million years later, was to form into the Edwards Aquifer.
Molds of the footprints will be placed on display at the Witte. The original footprints will remain on display at Government Canyon.
"Discovering that dinosaurs once lived in what is now Bexar County contributes significantly to the area's natural history," Adams said.
