Pliosaur sp. indet.
Three matrix free marine reptile vertebra. All three have been knocked around in the river gravels so the reservation is not the best. One shows signs of predation. Not that 'pretty' but a real bargain at only £12 each.
Jurassic, Kimmeridge Clay.
Oday, Abingdon, Oxfordshire.
Vertebrae : 11 cm, 11 cm and 10 cm wide.
