Gogia is Cambrian cystoid that is among the earliest and most primitive 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.

This association plate contains three complete dawn crinoids, in addition to a Bolaspidella housensis trilobite and a few tiny brachiopods, three distinct marine creatures coming out of the Cambrian explosion.
