£1.00
The Phylloceratina, Lytoceratina and Ammonitina of the upper Valudavur Formation (Valudavur Group or Anisoceras Beds of authors) collected near Pondicherry, south India, are revised on the basis of the collections of the Natural History Museum, London, notably those described by Forbes (1846). Twenty species, referred to thirteen genera, are recognized. The fauna is considered to come from equivalents of a part of the lower Upper Maastrichtian Belemnitella junior belemnite Zone of the north-west European sequence, and the lower part of the Abathomphalus mayaroensis planktonic foraminiferal Zone. It represents the most diverse Upper Maastrichtian ammonite assemblage known.
