This Waldron shale breaks down in water quite easily and after isolating the fossil from the slab with an engraver, dental pick, pen knife, and spray bottle. The shale flake containing the fossil was put on a microscope slide and these images were produced. I used a needle tool to move more matrix from the fossil which revealed how fragile it and the matrix was. The scolecodont had cracks and pieces did break off after being separated from the majority of the matrix. This fossil is not a resilient as the Ordovician ones I am use to working with. My intent was too look for the serrated edge that runs along the top of the fossil. It was found at 100x magnification (though not very photogenic).
Unsure about its name and I have not really researched Silurian Period scolecodonts before. Most of the sources I know are on the Ordovician ones found east of the city.
