This cabochon of Crinoid Marble has nice patterns. Crinoids are unusually beautiful and graceful members of the phylum Echinodermata. This is the phylum that brings you starfish, sea urchins, and sand dollars. The crinoids are a breed apart however, they resemble an underwater flower. Some even have parts that look and act like roots anchoring them to the ocean floor. They are commonly called sea lilies. Their graceful stalks can be meters long. Other varieties have no stalks or root like parts. They are commonly known as feather stars. Unlike the sea lilies the feather stars can move about on tiny hook like structures called cirri. Crinoids are alive and well and living in an ocean near you! They are also some of the oldest fossils on the planet. The earliest come from the Ordovician Period. At least the earliest that everyone agrees on.
