Cryptocrinus cerasus SOLD

Eocrinoid.

Eocrinoids are among the oldest groups of echinoderms, appearing in the Early Cambrian and becoming extinct in the Silurian. Eocrinoids were benthic and sessile marine animals. Like most echinoderms, their bodies were protected by a set of interlocking calcareous plates, forming a teak solid and elongated, often shaped like a sac or a rounded cone, containing the mouth in the center, surrounded by arm-like appendages called brachioles and the other end of the teak was a fixing organ that was attached to the substrate and that in some genus may be absent.
