Tertiary nuculoids and arcoids of eastern Patagonia (Argentina)

This paper provides the systematic analysis of the marine nuculoids and arcoids bivalves occurring in the late Eocene-late Oligocene strata exposed along the eastern coast of Patagonia (southern South America, Argentina). A summary of ages and stratigraphic relationships of the deposits containing t...
