Description:
Large test, finely grained and smooth. Rhomboid in transverse section, chambers partially inflated and sutures distinct. Aperture wide intermarginal ovoid, periphery acute.Occurrence:
Infrequent occurrence in M. basispinosus and V. herricki Zones in Venezuela. Offshore Cabinda rare, found in CABGOC 128-3 between 5,000’ and 10,160’, and in CABGOC 115-1X between 6,360’ and 8,760’.Remarks:
Renz noted the taxon from the Araguatian and Lucian of the Agua Salada Basin. The species was originally described from the Tertiary of the Vienna Basin. Recognised in the Miocene of the Gulf of Suez region (Souya 1965). Specimens compare well with those of the Burrow and Holland collection (slide G, NHM), and to those labelled Plecanium abbreviata of the Brady collection (NHM).
