So, in a previous post, I asked for the identification of a piece of an orthocone nautiloid. The general consensus was that it was a Spyroceras sp, or related genera. Now, I have found two specimens, which show some of the characteristics that that piece had. I first thought that they were nautiloids, but since they both had the same general structure and orientation, I began to wonder if they are Conularids. The morphology does not seem right, namely the separation between parts of the internal mold and its large segments; but I am at a loss to think of something better. The two specimens are shown below. In the first picture, the first specimen is shown. I did not recover the other side of it, as I had to prep this specimen out. The bottom of the specimen is of the internal mold, while the top of it is of the external. The second picture is of a closeup of the top of the first specimen. The third and fourth pictures are of the second specimen. The third picture shows the external mold on the left, and the internal mold on the right. The fourth picture is orientated in the same way. The scale is in millimeters. Both specimens are from the Leighton Formation, Maine; which is Silurian, Pridoli. Thanks in advance!
