Dinosaur tracks revealed as river dries up at drought-stricken Texas park

Dinosaur tracks that date back approximately 113 million years were found in Dinosaur Valley State Park, Texas recently where a river bottom was exposed after a severe drought.

Dinosaur Valley State Park, located on the Paluxy River outside Fort Worth, offers dinosaur track observations and 20 miles of camping trails. The park was impacted by a statewide drought last week.

"This is not normal for us, but due to two consecutive years of high temps and drought conditions, it has given us the opportunity to uncover new tracks," said Paul Baker, retail manager at Friends of Dinosaur Valley State Park. "Once we receive a decent rain most of the tracks will be covered up again."

The riverbed tracks, which are typically submerged by water and sediment, are now easily visible to visitors.

Two different dinosaur species' tracks were found in the park. One set is from an Acrocanthosaurus, weighing 7 tons and measuring 15 feet tall. The other might be from a Sauroposeidon, weighing 44 tons and measuring 60 feet tall. Stephanie Salinas Garcia from the park's press office confirmed this to CBS News.

With the help of dedicated volunteers, hidden dinosaur footprints were unearthed at the state park by brushing away dirt and dust. Renowned researcher Glen Kuban, who has been studying tracks at the park for over four decades, along with members of the esteemed Dallas Paleontological Society, will now map and cast the tracks with utmost precision for future interpretive purposes.
