These complexities make them very useful for distinguishing species. The term suture pattern refers to the featured line that makes contact with the septa and the interior of.

Ammonite Suture Patterns - These complexities make them very useful for distinguishing species. Present theories of suture formation deal with function rather than morphogenesis. Ammonoid suture patterns show more complexity in comparison to the nautiloids whose sutures are comparatively simple. The explanation of the morphology and morphogenesis of am­ monite septa is an old and unresolved prob­ lem in paleontology. 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 wavy septa can form if the.
