ABSTRACT: The studied section of the Chari Formation exposed at Fakirwari Dome, Kutch yielded rich foraminiferal assemblages comprising 54 species, ofwhich 22 are reported for the first time from the Indian region. The foraminiferal species are systematically described and employed for interpretations of age, paleoecology, and paleobiogeography. Although most of the foraminiferal species are rather long ranging, on the basis of a few species characteristic of the Callovian in diffrent parts of the world, a Callovian age is assigned to the studied sequence. Based on the dominance of suborder Lagenina, superfamily Nodosariacea, family Vaginulinidiae, calcareous hyaline forms, genus Lenticulina, wide ranging and fluctuating Fisher index, morphogroup K, and potential deep infaunal life habit group in the present assemblages, a shallow water, near shore, open marine middle shelf environment with frequently fluctuating shoreline having normal salinity and nomal to high level of oxygen is envisaged for the studied assemblages. The Middle Jurassic Fakirwari foraminiferal assemblages are assigned to a separate province of the Antiboreal Realm, the Indo-East African Province, located at the southern margin of the Tethyan Realm and transitional between the Tethyan and the Antiboreal realms.
