Stratigraphy
Formation:Quilon Limestone
Stratigraphic resolution:formation
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 "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

Collection methods:field collection,survey of museum collection
Reason for describing collection:biostratigraphic analysis
Collection method comments: COLLECTOR: From multiple collections, including the present author Dey, A. K. and E. H. Pascoe (1926-1927's), General W. Cullen (c. 1850's), W. Logan (1883). REPOSITORY: British Museum of Natural History.
Taxonomic list comments:COVERAGE: Exhaustive for gastropods and bivalves. Forams and echinoids mentioned to be present, but not listed. NOMENCLATURE: Antiquated, but with consistent use of subgenus and species-level assigments.
