Abstract

A flint erratic slab bearing a shell of the large inoceramid bivalve Volviceramus involutus (J. de C. Sowerby), with the valves oriented in a post-mortem ‘butterfly’ association, was collected from glacial float in an area of superficial deposits at Crimplesham, west Norfolk. This mollusc is typical of the Chalk and may be confined to the Coniacian. The shell is infested by encrusting oysters, Pycnodonte (Phygraea) vesiculare (Lamarck), and bryozoan borings, Foraripora pesavis Voigt and Soule. Infestation was most probably post-mortem.
