In these Cambrian limestones there is considerable infrastructural encrinites that are much common in the lower zone of limestone. The pieces are then always less than 3/8 of an inch and of any length of 1, 3 inches though more commonly around 2 inches. These pieces of the low zone limestone are more often directed through or often stand at various angles. Baron calls these 'edge-wise encrinites' but the rule is not to find them standing on an edge. This making is undoubtedly due to wave action in shallower sea, say in depths of more than 100 feet and less than 200 feet.
