Data from: Mollusks from the upper Shackleton Limestone (Cambrian Series 2), Central Transantarctic Mountains, East Antarctica
An assemblage of Cambrian Series 2, Stages 3–4 conchiferan mollusks from the Shackleton Limestone, Transantarctic Mountains, East Antarctica is formally described and illustrated. The fauna includes one bivalve, one macromollusk and ten micromollusks, including the first description of the species X...
