The Stratigraphical Lexicon of Venezuela was published in , and represented a thorough compilation of all published and much unpublished information on the character, nomenclature, correlation and ages of all the stratigraphic units then recognized in the country,. The Lexicon includes summary articles on the distribution of sediments and the paleogeography in intervals then assigned .

      The herein presented freshwater ostracod assemblages corroborate well with this interpretation.

redmondi. The distribution of ostracodes suggests correlation with the upper Miocene of Trinidad and northeastern Venezuela. The brackish-water ostracod Cyprideis thrived from the Mid- to Late Miocene; gypsum-bearing sand and mud sediments were also deposited widely in the shallow brackish-water lake environments.

This situation is similar to that of the Qaidam Basin, which lies to the south of the Altun Mountains. The ostracods of the Miocene Marada Formation from three wells in the east of the Sirt Basin are described.

These indicate ages ranging from Aquitainian to Tortonian. Four biozones are recognised: Pokornyella deformis minor (=Aquitainian), Aurilla soummamensis (=Burdigalian), an interval zone of Mid Miocene age, and Ruggieria tetraptera tetraptera (=Tortonian). 55 species have been identified.

During the Miocene, sedimentation rate increased; from the end of the Middle Miocene to the end of the Late Miocene, it increased to mm a −1 with some – m of Upper Miocene strata. During the Pliocene, the rate further increased to mm a −1: around m thickness of sediments were deposited during the Pliocene, largely as.
