MURGABIAN (UPPER PERMIAN) WITH FUSULINOID S FROM HYDRA, CRETE AND MYTILENE-ISLANDS (GREECE)

A chronostratigraphical summary of the controversial Tethyan Murgabian stage in Greece is given. Some biostratigraphical aspects of the Murg abian deposits from three greek islands are described : Hydra with Neo schwagerina craticulifera and Chusenella conicocylindrica; Crete with Neoschwagerina margaritae and Staffellidae; Mytilene, where the Murgab ian is pointed out for the first time, with Neoschwagerina craticulife ra a and Chusenella minuta. Several implications about the Fusulinoids repartition and about the Western Tethys paleogeography are indicated .
