Where: Alachua County, Florida (29.6° N, 82.4° W: paleocoordinates 29.7° N, 75.8° W)
• coordinate based on political unit
• small collection-level geographic resolution
When: Whitneyan (33.3 - 30.8 Ma)
• "The absence of mammals from I-75 that are clearly indicative of the Arikareean (e.g., Nanotragulus) favors a Whitneyan age, probably late Whitneyan (about 30–31 Ma; Prothero and Emry, 2004)" (Morgan et al. 2019)
•"the greatest depth of the deposit... is probably not more than 6 feet"
• group of beds-level stratigraphic resolution
Environment/lithology: sinkhole; poorly lithified, black, silty, sandy claystone
Size classes: macrofossils, mesofossils
Collected by M. Kontrovitz, T. H. Patton in 1965; reposited in the FLMNH
Collection methods: bulk, sieve,
• "recovery of most of the specimens was accomplished by means of washing and screening techniques"
