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: Kunnam Member (Karai Formation), Middle Cenomanian (99.6 - 93.5 Ma)

• Ammonites included the species Turrilites (T.) acutus Passy, Hypoturrilites tuberculatus (Bosc), Hypoturrilites gravesianus (d'Orbigny), Scaphites obliquus (J. Sowerby), Scaphites daileyi Wright, Sciponoceras baculoide (Mantell) and Sciponoceras rota Cieslinski, an assemblage suggesting either a Lower or Middle Cenomanian age (R.A. Henderson, personal communication December 1998). With reference to the generalised stratigraphic succession of the Ariyalur district in Sundaram et al. (2001, fig. 5) and Gale et al. (2002, fig. 3), we propose a probable Middle Cenomanian age for the Locality 1 records and a stratigraphic location toward the base of the Kunnam Member.
