Conodonts?

[Bringing Fossils to Life]

Fro a while now I've found these strange, conodont-like structures on the exteriors of rocks found in Seven Stars, Pa (Mahantango formation, Late Middle Devonian). They appear similar to Prioniodininid elements, but I have not been able to identify them precisely. The second picture even looks like an Ozarkodinid and preserves at least 3 elements. In the 3rd, another element can be seen below the one highlighted. Any ideas? Scale in first picture roughly 1 mm, all magnified circa. 60x.

I'm not seeing conodonts here.
