Unknown Ordovician Tube Fossil

This rock plate was found in Carroll County, Kentucky in the Kope Formation. It has a 3 cm long tube like fossil that I cannot identify. The fossils in the rock date to the Ordovician Period.

[UPDATED: Thanks to Solius to pointing out an error in this post, the fossil was not from Franklin County, Kentucky. Also magnified images have been added.]

Magnified 40x using microscope of both ends of the trace fossil and a sample shot of the mid-section.
