I just posted a picture of the Giant Ammonite on academia.edu that I recently purchased ...[www.academia.edu] Here. Notice what a sharp angle the shell is at? Compare it to the regular ammonites in the photo. that were getting caught by mososaurs I'll bet this guy could move at light speed compared to other ammonites.

Oh, wait I just realized I don't have a site report on this ammonite. I guess it isn't a real ammonite then. Oh, well, it will make a nice door stop then.
