Re #1150 - Cantaure Formation (Miocene of Venezuela)

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".

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; unlithified, micaceous, shelly/skeletal, silty claystone

• Tropical shallow-water assemblage, neritic, no deep-water genera present, normal salinity, perhaps nearby brackish source.
• Clay, massive, micaceous, slightly silty, and locally containing abundant fossils.

Size class: macrofossils

Reposited in the BMNH, NMB, PRI, USNM

Collection methods: quarrying,

• All material is reposited in the Natural History Museum (NMB), Basel, Switzerland, with some voucher specimens in the British Museum, PRI, and USNM.
