Sagenocrinites

Sagenocrinites The stem of Sagenocrinites is cylindrical and composed of numerous very thin columnals. Its crown is very broad and oval in shape. The polygonal plates of the lower arms display clear growth lines and form part of the cup. The free parts of the arms are short and are made up of many small plates. HABITAT The very compact form of this species suggests that it had adapted to relatively turbulent sea bed conditions.
