Everything old is new again, as the drought brought to light some previously unknown dinosaur tracks at a Texas state park last week. The 113-million-year-old tracks were discovered in a riverbed at Dinosaur Valley State Park in Glen Rose, Southwest of DFW. The Paluxy River runs through the park, and the tracks were exposed after stretches of the river dried up. The area has since had some heavy rain, so the tracks are under water and out of sight again.
