At Dinosaur Valley Park near Fort Worth, Texas (USA), dinosaur tracks discovered in dry Paluxy riverbed after extended drought. The traces date back to about 113 million years ago, they come from an Acrocanthosaurus dinosaur that could reach 12 meters and weigh 7,2 tons. These deep tracks were previously buried, filled with sediment and covered with water, something that helped to preserve them. “Because of the extremely dry conditions this summer, the river has completely dried up in most places, event that revealed new tracks in the park', said Stephanie Salinas Garcia, from the Texas Parks and Wildlife Department.
