Summary:

The pectin like pelecypods of the Devonian can be beautiful with their regular concentric ornamentation highlighted by radial ribs and "wings" along the hinge line. The fossil below is one that I do not recognize but I think I found a name for it while perusing the "Field Guide to the Devonian Fossils of New York" by Karl A. Wilson, 2014, Paleontological Research Institution.On page 148-149 is a pelecypod called Lyriopecten orbiculatus whose description is "Roughly circular shell with short hinge line, very small to absent anterior ear, and small posterior wing. Left valve convex, right valve slightly convex to concave. Surface marked by strong rays crossed by sharp concentric growth lines."The shell I found is a right valve, although it's seen in reverse as it's a mold of the original, slightly convex with strong rays and concentric growth lines. It came from the Panther Mountain formation (Devonian, Givetian stage) in a quarry along Cole Hill Rd. in Madison County, NY.
