Abstract
Broken ammonite debris is common in the Lower Oxford Clay and is thought to be attributable in part to the activities of predators. A new specimen of Kosmoceras (Zugokosmoceras) cf. obductum (Buckman) displays a series of bite marks in the region of the peristome suggestive of the dentition of the fishes Lepidotes, Heterostrophus (Semionotidae) and Mesturus (Pycnodontidae).
