Harder and Harder to obtain fossils from this private quarry in Middleport, New York

This great example of a Rochester Shale Fenestella Bryozoan that is from the Silurian deposits of New York. It was collected decades ago and just recently prepared by our prep lab.

This is an exceptional  plate with a Rochester Shale Fenestella.

Fossils especially this Rochester Shale Fenestella Bryozoan from the Middleport Quarry 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. Bryozoans are also referred to as moss animals so they are actually animals and not plants.

This Rochester Shale Fenestella plate are actually animals sometimes called sea fans. 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.

This Rochester Shale Fenestella 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 is an outstanding Rochester Shale Fenestella. The Fenestella are colonies of Bryozoans that consist of stiff branches that are interconnected for a “window-like” appearance. In Latin fenestra means window. Upon death these creatures usually break apart into very small fragments. It is quite rare to find larger pieces such as this.

The Fenestella are 3/4 inches by 1 inch and 1 x 1 inch sitting on an irregular matrix 4 1/4 by 3 1/2.

This is definitely a must have for Rochester Shale Lagerstatte collectors.
