Dactylose

Distinguished by its elongated dactylose form, and by the bold longitudinally striped pattern of the epidermis.

It consists of a little calcareous cylindrical column, about one tenth of an inch in height, attached by a dactylose base, and surmounted by an expansion in the form of a reversed cone, the margin of whose wide end is extended into several radiating arms, which, like the rest of the fossil, are entirely calcareous.

In front of them on the ventral surface is a pair of short dactylose processes, bluntly rounded at their tips; the abdomen is lacking.
