This is an extremely rare echinoderm fossil. It is a fabulous Helicoplacus sp. from the Lower Cambrian of California. This amazing specimen was found in 1963(!), and was recently acquired from the original collector. Helicoplacus is the EARLIEST unequivocally identifiable echinoderm. Helicoplacus is not radially symmetric and has three fold symmetry, instead of the typical five fold symmetry of most echinoderms. This plate displays a single individual in textbook fashion. The structure is easily seen, and the fine detail is just amazing, especially under magnification. The ancient echinoderm is beautifully showcased on the natural plate of shale. This is an extremely collectible specimen of Helicoplacus, one of the most important and unusual Lower Cambrian echinoderms in the world.
