Where: India (11.2° N, 79.0° E: paleocoordinates 47.9° S, 43.0° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Karai Formation, Middle Cenomanian (99.6 - 93.5 Ma)
• Containing the Middle Cenomanian Calycoceras newboldi (Kossmat). A single, imperfectly preserved valve of Inoceramus (L) pictus J. Sowerby of indeterminable subspecies is included in the Locality 3 material, suggesting an age-range of Middle to Late Cenomanian (Turrilites acutus Zone) and Early Turonian (Watinoceras coloradoense Zone) (Dhondt 1992, Hancock 2000, Troger 1989, Crame 1981). Previous records of I. (I.) pictus from the Pondicherry Sub-basin (Karai and Kulakkalnattam Formations) are by Chiplonkar and Tapaswi (1974) and Ayyasami and Banerji (1984), the latter (Karai Formation only) associated with the ammonites Eucalycoceras pentagonum (Jukes- Brown and Hill) and Pseudocalycoceras harpax (Stoliczka) and consistent with a Middle to Late Cenomanian age.
• group of beds-level stratigraphic resolution
Environment/lithology: lithified, sandy limestone
