Description
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 Fossil Stephanocrinus and Cephalopod from the Rochester Shale of New York.
This Silurian Fossil Stephanocrinus and Cephalopod were 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. Though the Dawsonceras Cephalopod is slightly damaged it is a very fine piece.
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,
This Fossil Stephanocrins and Cephalopod were actually animals. The Stephanocrinus was related to modern day starfish and they are echinoderms. But the Cephalopod is related to modern day octopus. They have modern relatives 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.
Silurian Stephanocrinus 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. 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 Stephanocrinus is just under 1/2 inch long and the Cephalopod is 2 1/2 inches long on a roughly triangular matrix 4 1/2 by 3 1/2.
