The Glendon Limestone is a geologic formation in Mississippi. It preserves fossils dating back to the Paleogene period.
Physeter is a genus of toothed whales. There is only one living species in this genus: the sperm whale. Some extremely poorly known fossil species have also been assigned to the same genus including Physeter antiquus from the Pliocene of France, and Physeter vetus from the Quaternary of the U.S. state of Georgia. Physeter vetus is very likely an invalid species, as the few teeth that were used to identify this species appear to be identical to those of another toothed whale, Orycterocetus quadratidens. The name is from Greek φυσητήρ (physētēr) 'blowpipe, blowhole .'
The Dresbachian is a Maentwrogian regional stage of North America, lasting from 501 to 497 million years ago. It is part of the Upper Cambrian and is defined by four trilobite zones. It overlaps with the ICS-stages Guzhangian, Paibian and the lowest Jiangshanian.

The Marianna Limestone is a limestone geologic formation located in Alabama, northwestern Florida, and Mississippi.
The Prairie Bluff Chalk is a geologic formation in Alabama and Mississippi. It preserves fossils dating back to the Cretaceous period.
Yazoo Clay is a clay geologic formation in Alabama, Louisiana, and Mississippi. It was named after a bluff along the Yazoo River at Yazoo City, Mississippi. It contains is a type of clay known as montmorillonite, making it a poor foundation material due to the fact that moisture causes extreme changes in volume. Sand, pyrite, and marl have all been noted in the formation. It preserves fossils from the Eocene, including the prehistoric cetaceans Basilosaurus and Zygorhiza, and the marine snake Pterosphenus. Sharks, rays, eels, and fish have also been found from the formation.
