Here is your chance to own a classic fossil from a classic site.
HARDER and Harder to obtain fossils from this private quarry in Middleport, New York
This Crinobrachiatus and other fauna was collected decades ago and just recently prepared by our prep lab..
Here is a Super detailed crinoid from a classic site in NY.
Fossils especially this Crinobrachiatus and other fauna 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 Nice Crinobrachiatus Crinoid is actually an animal related to modern day starfish so they are echinoderms. They have modern relatives also called 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.
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.
This Crinobrachiatus and other fauna 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.
The block is a gray colored matrix 3 3/4 inches.
