Abstract
Cymatonautilus is a new record from Kutch with precise stratigraphic b ackground. Being a temporally restricted but geographically widely dis tributed genus, Cymatonautilus is considered as a fleeting taxon. It c ryptically appeared during the latest early Callovian and survived onl y up to the middle Callovian, but dispersed rapidly through a long bel t on both sides of the Tethys. Its systematic position is revised, and derivation from paracenoceratid lineage is suggested.
