A HISTORY OF SUFFOLK 



the same deposit and locality have been obtained teeth of the shark. 

 Odontaspis cuspidata} 



So far at least as published records are concerned vertebrate remains 

 appear to be exceedingly scarce in the Suffolk Chalk, and no species 

 seem to have been named from that formation in the county. Probably 

 fish teeth have been obtained from some of the chalk pits of the county, 

 but it must suffice to mention that the British Museum possesses some of 

 the well know^n crushing teeth of the ray-like Ptychodus latissimus from 

 the Upper Chalk of Orford/ As regards fossils from pre-Cretaceous 

 deposits there is a vertebra of Ichthyosaurus thyreospondylus from the 

 Kimeridge Clay of Stanton near Bury St. Edmunds in the collection, 

 last named.'
