Geography
Country:Panama
Coordinates: 9.2° North, 79.9° West (view map)
Paleocoordinates:7.7° North, 77.5° West
Basis of coordinate:estimated from map
Geographic resolution:outcrop
Time
Period:Paleogene Epoch:Oligocene
Stage:Chattian 10 m.y. bin:Cenozoic 4
Key time interval:Chattian
Age range of interval:27.82000 - 23.03000 m.y. ago
Stratigraphy
Formation:Bohio
Stratigraphic resolution:bed
Stratigraphy comments: The Bohio Formation overlies the Gatuncillo Formation conformably in most areas, although may lap onto the Gauncillo Formation or basement. The thickness of the formation is about 75 metres to as much as 450 metres. Smaller foraminifera from the basal part of the formation yielded a early Oligocene age. The upper part of the formation, from which the collections are derived yields larger foraminifera of late Oligocene age.
Lithology and environment
Primary lithology:medium lithified calcareous sandstone
Includes fossils?Y
Lithology description: Listed as "calcareous, medium-grained subgreywacke"
Environment:shoreface
Geology comments: No paleoenvironmental data reported, but given that these collections originate from marine tongues/wedges, they are likely to be shallow water. Other localities contain mixed marine, brackish, and freshwater taxa.
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils
Collection methods and comments
Collection methods:selective quarrying,field collection
Reason for describing collection:taxonomic analysis
Museum repositories:USNM
Collection method comments: Collected by Woodring (1954). Material is also held (but not specified for any specific collection) at Stanford University, Acad. Nat. Sci. Phil., Corenell University, PRI, U. Cal. and Cal. Acad. Sci.
Taxonomic list comments:Exhaustive for gastropoda.
