Caption: The suture lines are the edges of the partitions (septa) that divide the interior of ammonite shells into separate chambers. These are few and far between in some ammonite species and perplexingly contorted and delicate in others, as in the specimen here seen. Ammonites are an extinct group of marine invertebrate animals with spiralling shells, subclass Ammonoidea, class Cephalopoda, that lived in mainly in the Mesozoic era, between 245 and 65 million years ago The specimen here seen is Cleoniceras, its provenance being Cretaceous deposits in Madagascar. Actual width of this detail is 32 mm, diameter of the complete ammonite in question being 120 mm.
