Geography
Country:India
Coordinates: 9.0° North, 76.6° East (view map)
Paleocoordinates:1.9° North, 72.7° 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
Formation:Quilon Limestone
Stratigraphic resolution:bed
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Quilon Limestone, which overlie unconformably Archean granites, and are regionally overlain by the Late Miocene Wakalay beds. THICKNESS: From 1-1.25 ft thick limestone within section of about 40 ft thick. AGE: Early MIocene based on multiple sources, including ostracod biostratigraphy (Khosla and Nagori, 1989) and vertebrate (Sahni and Mitra, 1980). STRATIGRAPHIC POSITION: From entire formation, which is found at the base of this section.
Lithology and environment
Primary lithology:gray,yellow,blue poorly lithified argillaceous "limestone"
Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Limestone, impure, argillaceous, highly indurated, dull yellowish to bluish grey. The upper and lower parts are less compact and present less difficulty in extraction of fossils. LITHIFICATION: Ranging from lithified to poorly lithified.
Environment:carbonate indet.
Geology comments: ENVIRONMENT: Carbonate facies. Environment not discussed in text (at least that is available at present), but appears to be relatively shallow water.
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: Unknown. 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.
