Gogia spiralis Dawn Crinoid Fossil

This is an excellent example of the Cambrian cystoid Gogia spiralis. Gogia is an Eocrinoid and is among the earliest groups of echinoderms. For this reason they are sometimes called a "dawn crinoids". They had a vase-shaped body (calyx), covered by plates that were symmetrical and have a bifurcated brachiole, a slender arm-like structure for food-gathering that closely resembled those in cystoids.
