Where: Venezuela (4.9° N, 62.1° W: paleocoordinates 4.9° N, 62.1° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Late/Upper Pleistocene (0.1 - 0.0 Ma)
• STRATIGRAPHIC RELATIONS: Occurs in proximity to the Pleistocene-Pliocene Falca Sands (Richards 1962) that is 70 m thick. LITHOSTRATIGRAPHY: No lithostratigraphic units named in text. AGE: Pleistocene (Richards 1943, 1962) based on the high proportion of Recent species (89%). Late Pleistocene (Sangamon) age has been suggested by Richards (1938) for a similar fauna from Florida and Cozumel Island, Mexico (Richards, 1935, 1937). STRATIGRAPHIC POSITION: At no place observed do Pleistocene deposits occur higher than 12-15 ft above sea level.
• bed-level stratigraphic resolution
Environment/lithology: coastal; unlithified lime mudstone
Size class: macrofossils
Reposited in the ANSP
• COLLECTORS: Collected by H.G. Richards (1939). REPOSITORIES: Collections held in the Academy of Natural Sciences (ANSP) and the Museo de Ciencias Naturales in Caracas, Venezuela.
