A drought that has turned vast swaths of the American West into a tinderbox has unveiled a discovery in Texas â dinosaur tracks.
The prints were mostly left by the Acrocanthosaurus â a theropod that stood 15 feet, weighed 7 tons and roamed the area 113 million years ago. They emerged in recent weeks as the Paluxy River dried up almost entirely in most parts of Dinosaur Valley State Park in Glen Rose, a spokeswoman with the Texas Parks and Wildlife Department said in an email.
A video posted last week by a nonprofit organization that supports the park shows close-ups of the triangle-shaped tracks and claw marks pressed into the parched riverbed.
Hundreds of theropod tracks were discovered in the area, southwest of Dallas, roughly a century ago.
