Cornulites proprius?



Described by James Hall in 1876 as "elongate-tubular, obconical or trumpet-shaped bodies, rapidly enlarging toward the aperture, which is campanulate with the margins always imperfect." The Cornulites propius worm tube fossil is found in the Waldron Shale of Bartholomew County, Indiana. These creatures lived in the Silurian Period.
