Waccasassa River 9A
University of Florida Vertebrate Fossil Locality LV040
In bank of Waccasassa River about 5 miles southeast of Otter Creek, Levy County, Florida; 29.28° N, 82.74° W.
- Early Pleistocene Epoch; late Blancan land mammal age
- About 1.7 to 2.0 million years old (estimated)
Basis of Age
Biostratigraphic correlation with other Caloosahatchee Formation sites in Southwest Florida (e.g., DeSoto Shell Pit 1); vertebrate biochronology (presence of Megalonyx leptostomus, Neochoerus dichroplax, Capromeryx arizonensis, and Hemiachenia gracilis: species only known from late Blancan localities in Florida).
Land vertebrate fossils found in sandy layers in between beds of mixed quartz sand and mollusk shells, equivalent of Caloosahatchee Formation of south Florida.
Nearshore marine/estuarine/coastal beaches and marshes.
