HUGE 26 LB CRINOID SPHERE. This immense 8.5 inch diameter bowling ball size sphere weighs over 26 pounds and is almost composed entirely of hundreds of plates of crinoid stems that are 150 million years old from Henan Province, China. Crinoids are echinoderms, relatives of starfish and are mostly known from the plates that made up their long stems that were attached to the ocean bottom as they filter fed on small organic creatures. These stems easily broke up into the individual round plates when the crinoid died and in some areas comprise 99% of the fossils found in the rocks. The crinoid stems range in shape from straight sections to round and oval and in color from shades of pink to browns and blacks. Because of the rare pink color of some of the stems, this stone is known as pink marble.
