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

Cystoid and 2 Trilobites. Fossils especially this Caryocrinites cystoid, Dalmanites Trilobite and rolled Trimurus body section from this site are preserved in Spectacular detail. Because of the wide variety and number of these animals it is also assumed they lived in dense communities,

This Caryocrinites cystoid is actually an animal related to modern day starfish so they are echinoderms. They have modern relatives called 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 several species of Cystoids, 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.

These animals thrived in the warm shallow inland sea that covered the area during the Silurian Period some 420 million years ago. 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 one has exceptional detail . The Cystoid is 5 3/4 inches long. The Dalmanites is 2 1/8 inches long and they sit along with the Trimurus on a plate that is 10 by 7 inches.  inches long.  It has been meticulously prepared using air abrasive technology.

But there are bryozoans on the plate as well.
