Phylogeny of the Eocene Antarctic Tapetinae Gray, 1851 (Bivalvia: Veneridae) from the La Meseta and Submeseta formations

Systematic analysis shows that the Southern Hemisphere bivalve genus Retrotapes includes the Antarctic species R. antarcticus , R. newtoni , and R. robustus and recognizes for the first time the presence of Katelysia represented by K. florentinoi . Two new genera were erected in this study: Marciach...
