Stratigraphy
Formation: | Cantaure | ||||
Regional section: | Paraguana | ||||
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: 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". |
Lithology and environment

Includes fossils? | Y |
Lithology description: Clay, massive, micaceous, slightly silty, and locally containing abundant fossils. | |
Environment: | coastal indet. |
Geology comments: Tropical shallow-water assemblage, neritic, no deep-water genera present, normal salinity, perhaps nearby brackish source. |
Taphonomy

Collection methods and comments
Collection excludes: | all microfossils,some macrofossils,ichnofossils |

Collection method comments: All material is reposited in the Natural History Museum (NMB), Basel, Switzerland, with some voucher specimens in the British Museum, PRI, and USNM. | |
Taxonomic list comments:Exhaustive for Bivalvia and Gastropoda. Balanus, corals, numerous otoliths, and Calianassa fragments are commonly found, though not listed. |
