Web seven suture patterns were chosen to capture a wide range of sutural complexity: Web sutures display a great variety of mor phological patterns that have been widely used in systematic studies. Web ammonites are classified by the shape, structure, and ornamentation of their shells. Web therefore the origin of suture patterns can be reduced to the problem of the morphological evolution with time of the mantle in contact with the inner shell.
