The slight depression of Mogara, some 100 kilometres further north-west, is however cut out in Lower Miocene beds, lithologically somewhat similar to the Upper Eocene and Oligocene deposits of the Fayûm. Probably similar conditions obtained throughout, and the existence of vertebrate remains indicates the persistence of river-currents from the south. The fauna of the Mogara beds has only as yet been very incompletely examined, the locality being rather inaccessible.[85] SECTION XII.—PLIOCENE. We have presumed that in Miocene times the Fayûm remained land, no traces of deposits of that age having been recorded; possibly the area underwent considerable denudation during the Miocene and early Pliocene periods, but of this it is difficult to adduce definite evidence. The records of Pliocene times in the Fayûm may be classed as follows:— (J). _Marine deposits_ of Middle Pliocene age. (K). _Borings_ on rock surfaces, exact age doubtful. (L). _Gravel Terraces_, probably late Pliocene. } (or early } Pleistocene). (M). _Gypseous Deposits_, probably latest Pliocene. } _J._—=Marine Deposits: Middle Pliocene.=
