However, Suwannee Limestone is not present on an area known as Orange Island on the eastern side of the Ocala Platform due to erosion, nondeposition or both.
[3] Suwannee Limestone consists of a white to cream, poorly to well hardened, fossil rich, vuggy to moldic grainstone and packstone.
(USGS) The Suwannee Limestone preserves numerous calcifying marine invertebrates, including foraminifers, echinoids, bryozoans and mollusks.
Shark teeth belonging to Ginglymostoma and Carcharhinus are known from the Brooksville 2 site, which likely originate from the limestone formation rather than the fissure-fill fauna from the same locality.
Terrestrial vertebrates that inhabited this newly-exposed karstic landscape at the time sometimes became trapped within sinkholes that opened in the limestone, which filled up with sand and clay as fissure-fill deposits, fossilizing their remains.
