Then thin bedded lie. with the joint of the section correct^ crust mud shale. for about 20 feet^ these beds shunned in Helpura and have other Cataract fossils. The Heloprion dorocem is the basal shale along with Plec. transversalis, Favozites and other regular Catabract brachipods. The so foot of shale- lie. series has reddish bands in upper half.
