Revision of genus Retrotapes del Río (Bivalvia: Veneridae) in the eocene of Antarctica
The validity of the genus Retrotapes del Río is discussed and Retrotapes newtoni ( Wilckens), R. antarcticus (Sharman and Newton) and R. robustus (Stilwell and Zinsmeister), from the Eocene strata of the Antarctic Peninsula (La Meseta Formation), are described and illustrated. The stratigraphic rang...
