Platyceras dumosum? - Spiny Snail

My first spiny snail fossil find in the Devonian Period Jeffersonville Limestone of Jefferson County, Kentucky.  The fossil could be a Platyceras dumosum? (Conrad, 1840).  It is somewhat weathered but some of the bumps can be made out where spines once existed.

Next  image is from the book Kentucky Fossil Shells - A Monograph of the Fossil Shells of the Silurian and Devonian Rocks of Kentucky by Henry Nettelroth, 1889, Frankfort,  Kentucky, Kentucky Geological Survey, Plate XXIII, Figure 2 of the Platyceras dumosum (Conrad, 1840).
