This is a very nice Icthyocrinus Crinoid Calyx from the Rochester Shale of New York. This one has been prepared for cabinet and tabletop display. Due to the unique way it was preserved in the rock and the way the rock split it is prepared without the base of the calyx and the arms are still buried in the matrix block..

These crinoids were collected decades ago and just recently cleaned by our prep lab..
Here is a very detailed  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,

Crinoids look like plants and are also called “sea lilies,” but crinoids are actually animals related to modern day starfish. They are echinoderms. They have modern relatives living in the deep oceans today however then they lived in shallow salt water seas and lagoons. Because they lived during the Paleozoic and were most common during the Mississippian Period, which is sometimes known as the “Age of Crinoids.”

Although there were many species of crinoids, they shared a basic body styles consisting of a stem by which it anchored to the sea floor a cup which enclosed soft body tissues, and arms which filtered food from the water.

Crinoids 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. This silt eventually hardened into stone that preserved the crinoids in glorious detail.

This Ichtyocrinus Crinoid Calyx has great detail . It is 1 3/4 wide by 1 1/4 inch tall wide.  It has been meticulously prepared using air abrasive technology.
