@abc7chicago: Footprints left behind by a dinosaur walking through present-day Colorado around 150 million years ago were filled with rain recently, making for fascinating puddles. Videographer Barry Stevenson captured footage of the water-filled sauropod prints along the West Gold Hill Dinosaur Trackway, which is the world’s largest continuous dinosaur trackway. He said the video was taken on August 25. “Late-season rain filled the enormous footprints … making these remarkable tracks even more visible in the red sandstone 1,600 feet above Ouray, Colorado,” Stevenson told Storyful.
