A useful specimen for demonstrating the adult stage. The original is on display in the British Fossil Gallery at the Geological Museum, London. An exceptionally fine, large, complete adult, developed on both sides and showing over 5 whorls of typical serpenticone coiling. The specimen is mainly internal mould with some patches of test. Sutures including the last are visible and the body chamber occupies exactly one whorl, shows uncoiling of the umbilical seam, the terminal restriction and part of the peristome. The head is 35 mm long and is in a relatively simple style.

Size: 100mm diameter
