Alachua Formation

The Alachua Formation is a Miocene geologic formation in Florida made up of claystone, sandstone, and phosphorite, and it is especially important for the rich fossil record preserved in those deposits. Its fossils document animals that lived in or around Florida during the Miocene, including ground sloths, gomphotheres, sirenians, rodents, carnivores, horses, and other hoofed mammals. Reptiles include turtles, crocodiles, lizards, and fossil snakes, while aquatic finds include sharks, rays, and other fishes. Birds and amphibians also appear in the record. Together, these remains provide an important view of Florida’s Miocene environments and fauna.
