The specimen appears to be one of the following common finds for that region:
Fossiliferous Concretion: A common find in Western New York shales (like the Wanakah or Windom shales), these are sedimentary rock masses that often form around and preserve an assemblage of smaller fossils like mollusk shells or brachiopods.
Brachiopod Matrix: Brachiopods (ancient shell-like animals) are the most common Devonian fossils in the state. This rock may be a \"matrix\" containing numerous impressions or replaced shells.
Rugose (Horn) Coral: These solitary corals often leave behind textured, somewhat horn-shaped fossils and were very prevalent in the ancient reefs of this area.
