摘要：

An assemblage of Middle Jurassic (Bajocian) hybodonts is described from the Hamira and Joyan members of Jaisalmer Formation, Rajasthan state, western India. Four hybodont species are recognised based on isolated teeth - Strophodus jaisalmerensis, S. magnus, ?S. indicus and Planohybodus aff. grossiconus. The new assemblage, recovered from near-shore marine strata, represents one of the oldest records of Jurassic hybodonts in the entire Gondwana. Paleobiogeograhic considerations suggest a pathway for the migration of the genus Strophodus from Europe to Jaisalmer and Kutch basins in western India during the initial phases of the formation of these basins.
