Quilon Limestone (Quilon, Kerala) (Miocene of India)

Where: India (8.9° N, 76.6° E: paleocoordinates 1.8° N, 72.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Quilon Limestone Formation, Early/Lower Miocene (23.0 - 16.0 Ma)

• 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.

• formation-level stratigraphic resolution

Environment/lithology: poorly lithified, gray, yellow, blue limestone

• ENVIRONMENT: Carbonate facies. Environment not discussed in text (at least that is available at present), but appears to be relatively shallow water.

• 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.

Size class: macrofossils

Collection methods: 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.

Purpose of describing collection: biostratigraphic analysis
