Period: Paleogene Epoch: Late Eocene Faunal stage: Late Clarkforkian through early Orellan Absolute Age: ~55.8 to ~33.9 mya, calculates to a period of approximately 21.9 million years The Ocala Limestone is at or near the surface within the Ocala Karst District located in west-central to the northwestern part of the peninsula.

It is also within the Dougherty Plain District in the north-central panhandle where it easily forms karsts.

Its extremely fossil rich grainstone, packstone and wackestone and some chert is common in the upper facies.

Its permeable and transmissive properties allow it to form a vital portion of the Floridan Aquifer.

The Ocala Limestone overlies the Avon Park Formation and forms part of the Floridan Aquifer System.
