Coordinates: 11.9° North, 69.8° West (view map)
Paleocoordinates:11.2° North, 66.6° West
Basis of coordinate:based on nearby landmark
Geographic resolution:local area
Time
Period:Neogene Epoch:Miocene
Stage:Burdigalian 10 m.y. bin:Cenozoic 5
Key time interval:Burdigalian
Age range of interval:20.44000 - 15.97000 m.y. ago
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
Primary lithology:micaceous,shelly/skeletal unlithified silty claystone
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
Modes of preservation:body
Size of fossils:macrofossils
Collection methods and comments
Collection excludes:all microfossils,some macrofossils,ichnofossils
Collection methods:selective quarrying,field collection
Reason for describing collection:taxonomic analysis
Museum repositories:BMNH,NMB,PRI,USNM
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.
