Kimmeridgian metriorhynchid crocodiles from England
£1.00
Remains of metriorhynchid crocodilians are rare in the British Kimmeridgian. A new partial metriorhynchid skull, recently discovered at Westbury, Wiltshire is provisionally assigned to Metriorhynchus superciliosus, a common narrow-skulled species previously described from the Oxford Clay (Callovian) sequences of Peterborough. It is covered with encrustations on both dorsal and ventral surfaces, indicating a long period of exposure on the sea floor, in relatively oxic conditions, before burial. There is evidence for both predator damage and a phase of post-depositional deformation.
