Abstract

The argillaceous sandstones of the Ottakkovil Formation, dated as Early-Upper Maastrichtian (Pachydiscus otacodensis Zone) yield a diversified fauna of echinoids, gastropods, ammonites, oysters and rudists. The study of these rudists belonging to the species Bournonia mutabilis allowed to complete the only existing description and figures given by Stoliczka 1871 and to confirm, by means of the shell structure analysis, its attribution to the genus Bournonia and not to Durania as it has been recently suggested by some authors.
