Productellas are also found .Tfopiaoleptus carinatus is by far the 
most important , even if not, the most numerous , species of brachiop 
pod present. Among the Pelycypods, a large Cypricardeila resembling 
mature forms of C. bellastriata|( the length being nearly twice the 
height), is quite common, A few Leptodesmas are also found as well 
as an erect Aviculo( ?)pecten. Gastropods are fairly common, the 
genera being Pleurotomaria,Euoraphalis ,Aclisina, Loxonema, and Mur 
chi sonia. No corals, erinoids, trilobites, or cephalcpods were 
met with; nor was Spirifer disjunctus seen among the Brachiopoda; 
but among the latter the same cupuloid Orbiculoidea which was 
met with in the lower Tropiaoleptus zone at Brookton, is again see, 
seen here fairly commop. This zone is 7B10. 
12. Immediately above the Tropidoleptus zone , isfound alft. 
band ofshaie in the lower part of which, Chonetes scitulusand 
Ambocoeliaumbonata are very abundant. Leptodesmas are also quite abi 
undant.This zone( 7BI1) , is the highest from which any fossils have 
been obtained
