CYSTOID FOSSILS FOR SALE

Cystoids are extinct echinoderms similar to crinoids. Their anatomy consists of a stalk, theca (body) and brachials (feeding arms). Most lived fixed to the seafloor but some were more mobile. Like modern echinoderms, cystoids were arranged in a pentaradial (five-fold symmetry)pattern and had a water vascular system. They first appeared in the Cambrian Period and disappeared in the Carboniferous.
