Silurian Dawsonoceras Cephalopod Imprint

This was found somewhere in Louisville, Kentucky. I found the images on my computer but I did not note where it was found. It is Silurian period and probably Louisville Limestone. It is the imprint of a Dawsonoceras cephalopod shell. These are great finds when they still have parts of the shell texture. The growth lines are sinusoidal in nature and quite a work of art. One section of the fossil has some pyrite crystals.
