Sea lilies, relatives of s🎉ea urchins and starfish, appeared more than 500 million years ago. Despite their deceptively simple common name, crinoids were in fact complex and unusual creatures attached to the bottom of the seas. The present specimen is composed of the stalked crinoids with long rods attached to tentacled calyxes that once filtered food particles from the currents flowing past th✱em. This elegant bouquet of sea lilies provides a beguiling snapshot of the underwater world of the Paleozoic Era.
