Where: Falcon, Venezuela (11.9° N, 69.8° W: paleocoordinates 11.2° N, 66.6° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Cantaure Formation, Burdigalian (20.4 - 16.0 Ma)
• Clays, sandstone, and limestones of up to 75, thick, although no single section is completely exposed. Collection apparently derived from near middle part of that thickness. Overlies unconformably Cretaceous rocks and is conformably overlain by limestones on middle to upper Miocene. Jung (1965) regarded the collection as early Middle Miocene, though more recent authors, including Vermeij (2001) indicate an Early Miocene (Burdigalian) age. Formation formerly referred to as "Cerro Pelado". Díaz de Gamero (1974), based on planktic forams, assigned a Lower Miocene age to the Cantaure Formation, placing it in the Globigerinatella insueta and Praeorbulina glomerosa Zones of Bolli (1966) and Zones N7-N8 of Blow (1969). Rey (1996) confirmed this age based on the nannofossil assemblage, and placing it in the Helicosphaera ampliaperta and Sphenolithus heteromorphus Zones, NN4-NN5.
