GogiaComing from the Cambrian Spence Shale deposits of Box Elder County, Utah this is a fine multiple example of a NEW SPECIES of Gogia , a member of the Class Eocrinoidea. Eocrinoids (“dawn crinoids”), were among the earliest groups of Echinoderms. They had a vase-shaped body (calyx), covered by plates that were symmetrical and had a bifurcated brachiole, a slender arm-like structure for food-gathering that closely resembled those in cystoids. The early Eocrinoids were attached to the bottom by a thick holdfast. Later members had an elongated stalk much like the true crinoids which evolved later. This particular species is undergoing description, and differs from G. spiralis in its larger size and untwisted brachioles.
