Here is a Super detailed and rare crinoid from a classic site in NY.
The Stephanocrinus Crinoid Calyx from this site are preserved in great detail. Because of the wide variety and number of these crinoids it is also assumed they lived in dense communities,
Crinoids are actually animals related to modern day starfish. 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 common 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.
During severe storms these animals were ripped from the ocean floor and buried in soft mud. The soft mud and sand allowed these animals to be preserved in such detail.
This Stephanocrinus Crinoid Calyx thrived 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 occasionally buried the colonies in silt. This silt eventually hardened into stone that preserved the crinoids in detail.
This one is just under 1 inch long.
