Here is a Super detailed  cystoid from a classic site in NY.

Fossils especially this Crinoid Icthyocrinus Calyx from this site are preserved in Spectacular detail. Because of the wide variety and number of these Cystoids it is also assumed they lived in dense communities,

This Crinoid is  actually an animal related to modern day starfish so they are echinoderms. They have modern relatives also 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 Crinoid Icthyocrinus Calyx 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.

This Crinoid has exceptional detail . It is 1 3/4 by 1 1/2 inches wide.  It has been meticulously prepared using air abrasive technology. There is a repaired crack through the crinoid.
