21 Jan 2009, 9:04 PM  | Re: Does anyone know about the evolution of Ammonites?!? When i did a similar assignment the main fossils we could do were trilobites, ammonites and Graptolites. I chose ammonites. The main evolutionary changes in the Ammonites were an overall coiling then uncoiling, as well as a development of stronger shells with more ornamentation. I chose to do the uncoiling of the ammonites. |
