Where: Citrus County, Florida (29.0° N, 82.7° W: paleocoordinates 29.1° N, 75.1° W)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Ocala Limestone Formation, Priabonian (38.0 - 33.9 Ma)
• STRATIGRAPHIC RELATIONS: From the Inglis Fm of the Ocala Group, which is overlain by the Williston Limestone, and overlies the Avon Park Limestone; originally proposed as Inglis Member of Moodys Branch Fm by Vernon (1951). Scott (1991) reduced the Ocala Group to formational status in accordance with the North American Stratigraphic Code, because the formations within it were biostratigraphic rather than lithostratigraphic. Inglis Member/Formation corresponds with the informal lower member of the Ocala. AGE: Priabonian; stage assignment based on Baum et al. 1994. Lower member of the Ocala Limestone may be Bartonian (Cotton et al., 2018). STRATIGRAPHIC POSITION: Unknown position within formation.
• group of beds-level stratigraphic resolution
Environment/lithology: lagoonal or restricted shallow subtidal; shelly/skeletal, white packstone
Size class: mesofossils
