Fossils especially this Cystoid Bryozoan and Calymene from the Rochester Shale of New York 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 Cystoid Bryozoan and Calymene plate are actually animals. They have modern relatives that live in the oceans today. But then they lived in shallow salt water seas and lagoons. They lived during the Paleozoic and were most prevalent during the Mississippian Period.

These Cystoid Bryozoan and Calymene 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 plate has exceptional detail . The plate is a rectangular matrix 11 inches by 5 1/4 inch. It has 2 cystoid Theca 1 inch long each. And  there are two bryozoan bundles and one partially curled Calymene niagarensis.  Because of the rarity of multi species plates It has been meticulously prepared using air abrasive technology.
