Ancient Species -

Crinoids are sometimes called "sea lilies" because of their lily-shaped bodies borne on stalks. They are, however, a type of marine echinoderm. There were many variations of the basic design - some had deep, vase-shaped bodies while others  had tiny bodies; some had long stalks, while others were short, a few had no stalks at all.

Crinoids flourished in the Cretaceous Period (144 to 66.4 million years ago). In the "great extinction" at the end of the Cretaceous Period, those species of crinoids which lived near the surface of the sea were wiped out.

There are 800 species of crinoids still living today but they are unfamiliar to us because they live in the oceans at depths between 600 and 15,000 feet.
