Resumen de Ostracoda from the Jurassic System of Jordan
This study describes the general stratigraphical and environmental situation of the Jurassic exposed sequences northwest and west of Amman and their ostracoda contents. The sequence is generally composed of thick, massive, sandstones, carbonates, and overlain by gypsiferous marls. It is unconformably underlain by the Triassic system and overlain by the Lower Cretaceous sandstone. The strata have been subdivided into Dogger and Malm on the basis of their ostracoda contents. The ostracoda assemblages which have been encountered in certain horizons are identified and described for the first time in Jordan. The type sediments and the ostracoda indicate deposition on a shallow and marginal shelf environment interrupted by lagoons of arid, humid and tropical conditions.
