Abstract

The study of a rich Middle Oxfordian arnrnonite succession from Kachchh CW India) supplies new evidence to support the open biogeographic connections between the Submediterranean and lndo - East-African Provinces. The studied assemblage is precisely dated as Middle to Upper Transversarium Zone, (Middle Oxfordian), on the basis of representatives of Perisphinctes and Larche­ria, this finding being the first record of this West-European form from India. The dating of the assemblage is further strenghtened by the occuJTence of the tethyan form Gregoryceras
