Description

Here is your chance to own a classic fossil from a classic site. 2 Species Dendrocrinus.
HARDER and Harder to obtain fossils from this private quarry in Middleport, New York

This is a complete Crinoid that was collected decades ago and just recently prepared by our prep lab..
Here is a Super detailed fossil from a classic site in NY.

Fossils especially these 2 Species Dendrocrinus crinoids 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,

This Crinoid is  actually an animal related to modern day starfish so they are echinoderms. They have modern relatives also crinoids that live in the deep oceans today. So then they lived in shallow salt water seas and lagoons. They lived during the Paleozoic and were most prevalent during the Mississippian Period.
2 Species Dendrocrinus. 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 with a “holdfast”, a calyx which enclosed soft body tissues, and arms and pinnules which filtered food from the water.

These 2 Species Dendrocrinus  thrived in the warm shallow 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 an ocean delta system that periodically buried the colonies in silt. This silt eventually hardened into stone that preserved the crinoids in glorious detail.

This Crinoid has exceptional detail . It is 1 inches long and 1 inch wide.  It has been meticulously prepared using air abrasive technology. There is a repaired crack through the crinoid.

DENDROCRINUS
Silurian Period
Rochester Shale Formation
Middleport, New York

Exceptional plate of 3 crinoids, 2 species.

The plate shows the first crinoid along the stem and a crown at the top. Part of the crown is missing due to loss during removal. It is still very showy nonetheless. In the mass near the base of that crinoid is another with a jumble of brachioles and at the bottom of the jumble is the one DENDROCRINUS longidactylis, again in a partial jumble but the center is visible allowing such identification. Finally the last is to the right.

These have been prepared using micro abrasive technology.

But crinoids are becoming more and more rare from this location so to find any on the market is special.

This crinoid plate is 12 1/4 inches tall. It is 8 inches wide. It a roughly rectangular block of grey shale matrix.

A great addition to a collection of Rochester Shale fauna. Who knows when another will be found.
