Possible Fish Scale Fossil - Devonian Period


Pictured in this posting is a mystery fossil found in the New Albany Shale (Late Devonian Period). It was uncovered by splitting a nodule of shale. Size of fossil is  about 4 mm wide. Specimen was collected in Floyd County, Indiana, USA. It might be some sort of fish scale. I need to get some better microscope pictures of this fossil. The specimen somewhat resembles a Rhabdoderma scale (see the discussion at this link Mazon Creek Coelacanth scale).
