Paleocoordinates:2.2° North, 76.1° East
Basis of coordinate:stated in text
Geographic resolution:outcrop
Time
Period:Neogene Epoch:Miocene
10 m.y. bin:Cenozoic 5
Key time interval:Early/Lower Miocene
Age range of interval:23.03000 - 15.98000 m.y. ago
Stratigraphy
Stratigraphic resolution:bed
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From unknown lithostratigraphic unit (not stated in text) and hence lithostratigraphic relationships are unknown. AGE: Early Miocene, based on faunal correlations with lower Gaj of Pakistan and India.
Lithology and environment
Lithology description: SPECIFIC LITHOLOGY: Unknown. LITHIFICATION: Unknown, no specimens are figured.
Environment:marine indet.
Geology comments: ENVIRONMENT: No environmental data are reported in text, though apparently from shallow marine setting.
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils
Collection methods and comments
Collection excludes:some genera
Collection methods:surface (in situ),survey of museum collection
Reason for describing collection:biostratigraphic analysis
Collection method comments: COLLECTOR: Wayland or Davies (c. 1920). REPOSITORY: Presumably BMNH.
Taxonomic list comments:COVERAGE: Limited to representative forms of gastropoda and bivalvia. NOMENCLATURE: Not an authoritative publication and somewhat antiquated, though nevertheless, consistent use of subgenera and species-resolution assignments permit nomenclatural vetting.
