Not trying to be facetious, generally curious about why you would classify this as an ammonite, and not a nautilus? To my understanding, ammonites has more of pronouced spiral with the shell. The picture itself it heavily stylized and was drawn referencing this photo. There may be extra 'bits' in my drawing, but the anatomy is there. - http://www.aqua.org/~/media/Images/.....slide1-web.jpg
The only reason I classified it as an Ammonite was because the intricacy of the sutures on the shell in your drawing are more intricate than a typical nautiloid would have. They are even more intricate than the picture you were referencing. The Ammonite family had shells of varying degrees of intricacy, getting steadily more detailed up until their extinction in the Cretaceous Period. This figure shows a pretty good classification between ammonoids and nautiloids. http://higheredbcs.wiley.com/legacy...../nw0258ann.jpg
