Description
Here is your chance to own a classic Fossil Crinobrachiatus Crinoid from a classic site.
It is harder and harder to obtain creatures from this private quarry in Middleport, New York
This is an exceptionally rare specimen from the Rochester Shale of New York.
The Fossil Crinobrachiatus Crinoid is actually an animal related to modern day starfish and they are echinoderms. They have modern relatives called crinoids 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.
This plate contains a Fossil Crinobrachiatus Crinoid. This species is quite rare from the quarry and almost never found complete. This one is close. It lacks the calyx and arms but is a mostly complete version of this fossil.
This was collected decades ago and recently prepared in our prep lab. Here is a Super detailed and great crinoid from a classic site in NY.
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,
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 calyx, an round sac which enclosed soft body tissues, and arms and pinnules which filtered food from the water.
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.
The Fossil Crinobrachiatus Crinoid is 7/8 inches long and 1/2 inches wide. But it has spectacular detail and sits on a matrix block that is roughly triangular 3 x 3 inches.
