Gogia Eocrinoids From The Middle Cambrian Of Utah
Description: Coming from the Cambrian Wheeler Formation deposits of Millard County, Utah are fine examples of Gogia spiralis, 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 that evolved later. Gogia displayed an interesting ontogenic feature related to its arms. Once Gogia matured past the 4-armed stage (the species derives its name from the spiraled arms), they added arms in such a way as to have an odd-numbered total. Name: Order Echinodermata; Family Eocrinoidea; Gogia spiralis Geological Time: Middle Cambrian Fossil Site: Wheeler Formation, Millard County, Utah
