Hello, I got this cool little Scolecodont (annelid worm jaw) from the Ordovician Fairview Formation of Kentucky. It's tiny as one would expect at 3 mm long. Does anyone know what species it's from? I found a reference for IDing scolecodonts from Cincinnati Ohio: http://drydredgers.org/scolec2.htm, and Nereigenys seems like a decent match with my specimen, though the first two "hooks" are much more prominent on mine. These are also different localities.

I was recently looking at one of my cephalopod fossils when I came upon this. The only explanation I can come up with is that it is a scolecodont, the jaws of polychaete worms, and these have been found in the Hamilton group before (Arabellites sp.) However, I've never seen pictures of scolecodonts in which the jaw doubles back on itself as it does here. I included an interpretive drawing to show what I am seeing. The size appears to be a little bigger than what my book predicted scolecodonts to be; I cannot give a precise measure because my microscope does not show this information. Am I simply looking at the top, like in the famous Websteroprion reconstruction?

I came across this unusual scolecodont and can't identify it. Late Ordovician Drakes formation. Any help appreciated.

Hi again! Over the weekend, I posted pictures of small fossils in a rock I found at Mimico Creek in Toronto, Ontario (Georgian Bay Formation, Upper Ordovician). I've created this new post just for the shiny black specimens that I found in the rock because a consensus wasn't reached regarding their identity. Each of the two specimens pictured below are 5mm long. My question is: are these items scolecodonts or conodonts? I was leaning towards scolecodonts but I wanted to see what others have to say... Thanks once again! Monica

While prepping a Platystrophia ponderosa just now, I came across this little guy. I'm thinking Scolecodont. Thoughts? Stratigraphic context in tags. Scale in mm.
