CYTHERELLOIDEA (OSTRACODA) FROM THE UPPER CRETACEOUS BAGH FORMATION OF MADHYA PRADESH, INDIA: ITS AFFINITY AND PALAEOGEOGRAPHIC IMPLICATIONS

摘要

Cytherelloidea is a cosmopolitan Ostracoda genus having worldwide distribution. It occurs commonly in the Cretaceous shallow marine marginal basins of the erstwhile Gondwanaland viz. South America, Africa, Middle East, Madagascar, Australia and India. In the present work eight species of the genus have been recorded from the Bagh Formation (Tipper Cretaceous) of Madhya Pradesh, India. Of these, two species- Cytherelloidea awaldaensis and C. rosebaidaensis are new. The other reported species are Cytherelloidea oertelii Singh, C. oudiapurensis Jain, C. raoi Jain, C. subgranulosa Jain, C. thuatiensis Jain, and Cytherelloidea sp. Affinity and palaeogeographic implications of the genus Cytherelloidea are discussed.
