Ammonoid or Gastropod?... That Is the Question.

 Here are some pictures of a recent find at one of our work sites in Bullitt County Kentucky USA. It appears to be from the Louisville Limestone or might be dolomite. It dates to the Silurian Period.

Thanks to Levi for the fossil and now we will try to remove some of the matrix to see if any patterns are left from the shell that might give a clue as to what this creature was and maybe its name.

The bottom of the rock has an imprint of a bryozoan fossil.
