Top Shelf Gogia spiralis Dawn Crinoid Fossils

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.

Having collected hunderds of Dawn Crinoids, I can attest that they are found no better than this choice specimen. There is no calcite as often is found to obscure the fine details exhibited in these large specimens. The two crinoids shown here are in high relief and are very showy.
