Platyceras dumosum

Here is another picture of gastropod specimen posted earlier. It is from a different vantage point. My cousin found it in the Jeffersonville Limestone of Clark County, Indiana USA and has been slowly extracting it with a sand blaster.

It appears to be a Devonian Period snail (gastropod) called Platyceras dumosum (Conrad, 1840).
