Here is your chance to own a classic fossil from a classic site.
It is harder and harder to obtain fossils from this private quarry in Middleport, New York

This is an exceptionally rare and very often overlooked Silurian crinoid from the Rochester Shale of New York.

This Rare Stephanocrinus Crinoid Crown was collected decades ago and just recently prepared by our prep lab..
Here is a Super detailed  and rare crinoid from a classic site in NY.

Crinoids from this site are preserved in Spectacular detail. Because of the wide variety and number of these crinoids it is also assumed they lived in dense communities,

The Rare Stephanocrinus Crinoid Crown is actually part of an animal related to modern day starfish and they are echinoderms. They have modern relatives called crinoids living in the deep oceans today but then they lived in shallow salt water seas and lagoons. They lived during the Paleozoic and were most prevalent during the Mississippian Period.

Although there were many species of crinoids, they shared a basic body styles. The styles consisted of a stem by which it anchored to the sea floor with a “holdfast”, a theca, an oval sac which enclosed soft body tissues, and arms and pinnules which filtered food from the water.

Stephanocrinus Crinoids Crown was part of the animal that lived in the warm inland sea that covered the area during the Silurian Period some 420 million years ago. The crinoids living near what is now Middleport New York were established near a delta system that periodically buried the colonies in silt. It is because the silt hardened into stone that preserved the crinoids in detail.

This crinoid has exceptional detail . It has been prepared using air abrasive tools.

This Rare Stephanocrinus is just under 1/2 inch long on a roughly triangular matrix 1 3/4 by 2. There is also a Bryozoan on the plate.

There is also a small piece of the stem attached.
