EAST WEAR BAY. 53 



Very pretty specimens may occasionally be picked 

 up in the crystalline form, but all are interesting 

 from the curious shapes they assume. Many of the 

 fossil shells have become completely impregnated 

 with this substance so as to become veritable iron 

 shells. Veins of it too, may be traced here and 

 there in the clay. 



It would not be possible to give here a list of the 

 many hundreds of species of fossils that have been 

 found in the blue clay but I may mention some of 

 commoner kinds. A skeleton, almost entire, of one 

 of the ancient Mesozoic reptiles was discovered at 

 Copt Point very recently by Mr. Griffiths ; it was 

 probably over twelve feet long, and has been named 

 Mauisaurus Gardneri. A quantity of smooth quartz 

 pebbles was found with the bones, which, it is pro- 

 bable, had been swallowed by the animal, as pebbles 

 of all kinds are absent from the Gault. Teeth and 

 vertebrae of fishes of the shark tribe are to be found ; 

 and the remains of crabs and lobsters are far from 

 uncommon. 



The most attractive fossils in the bay are the 

 Ammonites and Belemnites. Of the former may be 

 found : 



A. splendens. A. lautus. 



A. auritua. A. tuberculatus. 



A. varicosus. A. interruptus. 



and many others. The commonest of the Beleni- 

 uites are B. minima, and B. Listen. Of other 

 chambered shells we get Hamites, Scapldtes, Ancy- 

 loceras, Nautilus, &c. 

 Of univalves we get the following genera : 



Rostellaria. Natica. 



Ttnrilites. Trochua,
