Geological significance of a Middle Cambrian fauna from Antarctica
A NEW collection of a Cambrian fauna, occurring as erratics in a Quaternary moraine near Mount Provender (80°23′S, 29°55′W), western Shackleton Range (Fig. 1, inset) is reported here. It includes inarticulate brachiopods and trilobites, together with the first hyolithids and primitive molluscs from...
