Giant Clam Fossils at the Platyceramus Hills

Join paleontologist Jim Kirkland on a tour of a giant clam fossil site in the Mancos Shale. These clams lived 85 million years ago, during the Age of Dinosaurs, when this part of Utah was under the ocean. The giant clam fossils reach 3 to 4 feet across and could have weighed as much as 50 pounds when they were alive.
