Web based on the characteristics of the obtained 3d structure, we explain how ammonites might have formed the complex suture patterns. Web ammonoid sutures are geometric patterns formed by the intersection of the septa and the shell wall, and have long been a diagnostic tool for ammonite researchers for such applications as species identification, taxonomic relationships, ontogenetic change, functional and evolutionary morphology, determination of ecological niche, and other. The term suture pattern refers to the featured line that makes contact with the septa and the interior of the aragonitic shell. 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. Ammonite conchs are separated into small chambers by septa, which might contribute to reinforce the shell.
