HARDER and Harder to obtain fossils from this private quarry in Middleport, New York.

A very wonderful and small LECANOCRINUS macropetalis crinoid calyx and a small CARTOCRINUS ornatus Cystoid theca from the Rochester Shale of Middleport New York.

Crinoids are actually animals and not plants as the common name “Sea Lilies” would suggest. They are Echinoderms, related to modern day starfish. They were filter feeders capturing their food with the long slender arms or brachioles. Cystoids are also echinoderms similar to the crinoids.

This is nice calyx exhibiting a very inflated calyx with the short stubby arms displayed.  The Cystiod is on the side of the block. These creatures inhabited the ancient Silurian Seas along-side many other species.This crinoid calyx is a must have for any collector of crinoids and especially of Rochester Shale fauna.

This crinoid calyx measures .59 inches by .5 inches, cystoid measures .48 inches by .43 inches and is on an irregular gray shale matrix measuring 4.5 inches by 4.25 inches

This is the specimen you will receive.
