Pliocene Mollusca (Bivalvia, Gastropoda) from the Sørsdal Formation, Marine Plain, Vestfold Hills, East Antarctica: taxonomy and implications for Antarctic Pliocene palaeoenvironments
Pliocene shallow-water marine sediments at Marine Plain (centred on 6837.7ʹS; 7807.8ʹE) and covering approximately 10 km in the Vestfold Hills, East Antarctica, have yielded six species of gastropods, and 11 species of bivalves from two beds within the Srsdal Formation. Most of the material is close...
