First record of Pressastarte zakharov and Pinguiastarte kelly (mollusca: Bivalvia) from the turonian (upper cretaceous) of the bagh beds, central India

Abstract

The genus Pressastarte Zakharov, 1970 and the subgenus Pinguiastarte Kelly, 1992 (Family Astardiae) have been recorded from the Turonian (Upper Cretaceous) of the Bagh Beds, central India for the first time. The Pressastarte Zakharov is represented by two species: Pressastarte (Pressastarte) lincolnshirensis Kelly 1992 and Pressastarte (Pressastarte) var. clavertensis Duff, 1978 in the Bagh Beds. Pressastarte (Pinguiastarte) senecta (Woods, 1906) and Pressastarte (Pinguiastarte) var. pressula Zakharov 1970 are the two recorded species of the subgenus Pinguiastarte. On the basis of the present record, henceforth the Pressastarte (Pinguiastarte) ranges from the Middle Jurassic (Middle Bathonian) to the Late Cretaceous (Turonian).
