I was collecting fossils in Clarksville, Indiana today at a site I typically find a large amount of Devonian fossils. Some recent rain had washed out a number of small fossils to easily collect. I collected this fossil without thinking twice, but since cleaning it up I realized it doesn't match any in my identification guide. I originally thought it was part of a crinoid stem, but I can't find any documentation to support that. I've spent the last several hours researching and cannot find a match for it. Now I'm at a bit of a loss and would love some input. Thank you!
