HARDER and Harder to obtain fossils from this private quarry in Middleport, New York
They are Echinoderms, related to modern day starfish. They were filter feeders capturing their food with the long slender arms or brachioles.
Exceptional plate of 3 crinoids, 2 species. These are both DENDROCRINUS. Two are celsus and the bottom one is longidactylis.
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.
However 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.
