Straight Shelled Nautiloid Cephalopods

Here are some molds of cephalopod shells found in Ordovician rock off of Bardstown Road near Mt. Washington, Kentucky. Maybe they are of the genus Orthoceras (maybe an old name) or Treptoceras.

  1. I found one of these in west central Indiana. The closest match is in the upper left corner only twice the size. It is oval in shape with well defined lines as well as a clear siphuncle running through one side. 6"x3 1/2"x 1 3/4". Any guesses on approximate length with alive. joerobert3@yahoo.com
