As Texas experiences record temperatures this summer and water levels drop due to drought, a group of volunteers has discovered something pretty remarkable: giant new dinosaur tracks believed to be 110 million years old. CNN.

Paul Baker, the retail manager at Dinosaur Valley State Park, told CNN he had “never seen so many dinosaur tracks.”

“It’s exciting to see something that no one has seen before; it’s almost like a treasure hunt in a way,” said Baker, who helps clear and map dinosaur tracks in the park. “I thought we’d seen all the dinosaur tracks there are, but in the last two years, with the drought we’ve had and the hard work of our volunteers, it’s just an amazing sight.”

Valley of the Dinosaurs State Park, about an hour and a half south of Dallas, is home to a large number of sauropod and theropod tracks that lived in the area about 113 million years ago. It’s a hot spot for dinosaur lovers and tourists, who usually come to the now-dry Paluxy River for fishing, swimming and kayaking.

As the water level receded this summer, the story unfolds.

“It was the hottest June I’ve ever had, and I’m 45 now,” Baker said. “I don’t remember the channel collapsing. Just dry.”
