Mooreville Formation

The Mooreville Formation is a Cretaceous chalk 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.
