The Mooreville Formation is a Cretaceouschalk deposit exposed in central Alabama. It formed from the fossilized skeletons of billions of tiny plankton between approximately 85 million years ago and 82 million years ago. Fossils of a new species of Lophorhothon atopus and other prehistoric creatures have been recovered from the Mooreville Formation.
