Here is a Super detailed and rare 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,
Crinoids are actually animals related to modern day starfish. They are echinoderms. They have modern relatives called crinoids living in the deep oceans today however 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 theca which enclosed soft body tissues, and arms and pinnules which filtered food from the water.
Crinoids thrived in the warm inland sea that covered the area during the Silurian Period some 420 million years ago. The cystoids 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.
