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

This is an exceptional and very rare Callocystites jewetti cystoid and stem from the Rochester Shale of New York. The stem does belong to this fossil, just a section was missing before prep started.

This Callocystites jewetti Cystoid were collected decades ago and just recently prepared by our prep lab..
Here is a Super detailed  fossil from a classic site in NY.

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

These are actually animals related to modern day starfish. They are echinoderms. They have modern relatives called crinoids living in the deep oceans today however then they lived in shallow salt water seas and lagoons. These lived during the paleozoic and were most prevalent during the Mississippian Period.

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

Cystoids thrived in the warm inland sea that covered the area during the Silurian Period some 420 million years ago. The cystoids 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 Cystoids in glorious detail.

This Cystoid has exceptional detail . It is 1 1/4 by 1 inches wide. The stem is 2 inches long and you get both the stem and theca.  It has been meticulously prepared using air abrasive technology.
