Notes

Remarks: The animal seen in Fig. 164 appears to be an irregular sea urchin, based on the overall shape and darker radial regions possibly representing ambulacra. It could belong to a number of different groups, including holasteroids, spatangoids and cassiduloids. The blurred nature of the image renders a more refined identification impossible.
