I recently chiseled this piece out of a Mississippian road cut exposure in north Tn, Fort Payne Formation, with a generous assist from TFF member @Herb. I apologize for lack of proper scale, measuring approximately 6cm x 7cm x 5cm x 10cm. I used a dremel, soaking, and scrapping method to remove as much of the hard limestone, but cannot remove the rest as the dremel bounces off the solid crinoid hash remaining. I am having difficulty with identifying where this would fit on the crinoid unless it is something similar to the proximal stem and branching arms shown on the illustrated figure by Ausich, W., Brett, C., Hess, H., & Simms, M. (1999). Crinoid form and function. Fossil Crinoids. http://paleoinver.materias.gl.fcen.uba.ar/index.php/download_file/view/106/129/ I appreciate the help! Thank you, Leah Bottom Front (for reference) Side Top
