Spectacular piece measuring ± 17 x 10 cm with a fossil crinoid measuring ± 3.8 x 3.8 cm.
*The eocrinoids "Dawn Crinoids" were among the first groups of echinoderms. They had a vase-shaped body (calyx), covered by plates that were symmetrical and had a forked brachiole, a thin arm-shaped structure for gathering food that closely resembled those of cystoids. The first eocrinoids were attached to the bottom by a thick retention.
