The identification of this crinoid calyx I am not so sure about. The illustration was created by J. C. McConnell for the 1881 11th Annual Report of Indiana Department of Geology and Natural History John Collett, State Geologist, 1881. It is on plate 42 and from the coal measure strata of Newport, Indiana. The crinoid is identified as Productus punctatus.
The next two pictures are of a Misissippian Period fossil that somewhat matches the drawing. It was found in the Indiana Springs formation of Crawford County, Indiana.
