Where: India (9.0° N, 76.6° E: paleocoordinates 1.9° N, 72.7° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Quilon Limestone Formation (Warkalli Group), Early/Lower Miocene (23.0 - 16.0 Ma)
• STRATIGRAPHIC RELATIONS: From the Quilon Limestone, which overlie unconformably Archean granites, and is locally overlain by the Ambalapuzha Fm (Miocene-Pliocene). 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
Size classes: macrofossils, mesofossils
Reposited in the NHMW
Collection methods: surface (float), surface (in situ), sieve,
• COLLECTOR: Collected by the authors, principally Reuter, Piller and Harzhauser. REPOSITORY: Presumably NHMW, Vienna.
