Cincinnatian Conodonts

Pictures of conodont pieces from Jefferson County, Indiana. These fossil pieces belonged to creatures existing in the Upper Ordovician Period of Maysvillian-Cincinnatian Stage.

Thanks to Kenny for the images. [UPDATED: Thanks to Solius Symbiosus for correcting me about these not being scolecodonts but instead conodonts.]

Every fossils is about 1-3 mm in length and have been magnified 20x.  Note they are also glued down to a slides so there is a residue in the background.

The coloring suggests that they are conodonts. Here is a nice site dedicated to micros:
