Description
Small Fossil Ichthyocrinus Crinoid Calyx and small bryozoan branch.
Here is your chance to own a classic fossil from a classic site. A nice showy piece as well
Harder and Harder to obtain fossils from this private quarry in Middleport, New York
This is a very nice Fossil Ichthyocrinus with stem. The Crinoid Calyx from the Rochester Shale of New York. This one has been prepared for cabinet and tabletop display. This one has a stem but it is quite small.
This crinoid was collected decades ago and just recently cleaned by our prep lab..
Here is a very detailed crinoid from a classic site in NY.
But the 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,
And though Crinoids look like plants and are also called “sea lilies,” but crinoids are actually animals related to modern day starfish. They are echinoderms. They have modern relatives living in the deep oceans today however then they lived in shallow salt water seas and lagoons. Because they lived during the Paleozoic and were most common during the Mississippian Period, which is sometimes known as the “Age of Crinoids.”
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 a cup which enclosed soft body tissues, and arms which filtered food from the water. This Fossil Ichthyocrinus with stem is flattened due to the weight of the sediment but it shows very well.
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. This silt eventually hardened into stone that preserved the crinoids in glorious detail.
This Fossil Ichtyocrinus with stem has great detail . It is 1 inch wide by 2 1/2 inches long. It has been meticulously prepared using air abrasive technology.
