A shell bed in the upper part of the Anaipadi Formation of the Trichiopoly Group near the villages of Pilimisai and Koothur in the Cauvery Basin, Tamil Nadu, south India yielded an abundant ammonite fauna assigned to the lower part of the Kossmaticeras (Kossmaticeras) theobaldianum Zone and to the lower Coniacian. The ammonite association of this interval in the Cauvery Basin is dominated by Mesopuzosia, Damesites, and Kossmaticeras (Kossmaticeras) species. The fauna is: Phylloceras (Hypophylloceras) masiaposensis (Collignon, 1956), Phyllopachyceras sp. , Tetragonites epigonus Kossmat, 1895, Gaudryceras (Gaudryceras) mite (Hauer, 1866), Mesopuzosia gaudama (Forbes, 1846), Damesites sugata (Forbes, 1846), Kossmaticeras (Kossmaticeras) theobaldianum (Stoliczka, 1865), K. (K.) recurrens (Kossmat, 1897, K. (K.) jonesi Collignon, 1965, Menabonites anapadensis (Kossmat, 1898), Lewesiceras sp., Placenticeras cf. kaffrarium Etheridge, 1904, Glyptoxoceras sp., and Scalarites sp.
