FOSSILS FROM THE UPPER GREENSAND.

of the portion charged with phosphatic nodules and fossils becomes 

 gradually less, till at Bookham this noduliferous part is not more 

 than six inches deep. The upper five or six inches of the rock in 

 the stone quarry on Dogbury Hill also contains a few such 

 phosphates and green-coated nodules, and one or two were found 

 in a quarry at Batcombe ; but the nodule bed which is so fossili- 

 ferous there and at Evershot is the basement bed of the chalk and 

 not the top of the Upper Greensand. 



The fossils in the Dorchester Museum have been obtained 

 mainly from exposures at Stoke Wake, Anstey, Melcombe Bing- 

 ham, and the roadways south of Armswell. The following is a list 

 of them, the first column indicating their mineral condition whether 

 phosphatic (P.) or with sandstone matrix (S.), the second column 

 showing how many occur as phosphatic fossils in the Gault or in 

 the Cambridge Greensand, and the third how many occur in the 

 Warminster Greensand :
