- An assemblage of lower Cambrian (Series 2, Stages 3–4) molluscan fossils from the Shackleton Limestone, Transantarctic Mountains, East Antarctica is formally described and illustrated. The assemblage is composed of one bivalve and ten helcionelloid molluscs, including the first discovery of the genus Xinjispira outside North China. The new fauna shows some similarity to previously described micromollusc assemblages from lower Cambrian glacial erratics from the Antarctic Peninsula. The fauna of the Shackleton Limestone is mainly composed of steinkerns, and of relatively low diversity, but the presence of key taxa, including the molluscs Mackinnonia rostrata and Pojetaia runnegari and the tommotiid Dailyatia odyssei strengthens correlation to the newly defined Dailyatia oddysei Zone of South Australia
