Description A rare and visually captivating Notoceras heteromorph ammonite fossil from the Cretaceous period, discovered in Madagascar. This exceptional fossil showcases the unique, non-planispiral coiling typical of heteromorph ammonites, with elegant, helical spirals and laterally compressed whorls. It is a genuine piece of Earth’s deep-time marine history and an excellent addition to any fossil, ammonite, or natural history collection. This Notoceras specimen comes from the Cretaceous strata of Madagascar, a renowned region for exceptionally preserved marine fossils. While the precise geological stage and zone for this piece are not specified, Notoceras fossils are typically associated with the Albian to Cenomanian stages of the mid-Cretaceous. The region’s marine sediments reflect a shallow marine depositional environment, abundant in molluscan fauna. Morphological Features: Strongly heteromorphic, uncoiled to loosely coiled shell Delicate ribbing and chambered structure visible Distinctive features help identify it within the Heteromorph ammonites Taxonomy: Genus: Notoceras Superfamily: Turrilitoidea Order: Ammonitida Class: Cephalopoda Phylum: Mollusca Notoceras, like other heteromorphs, represents an evolutionary adaptation from the typically planispiral ammonite lineage. These ammonites likely occupied different ecological niches than their coiled relatives, perhaps floating higher in the water column or using more passive means of locomotion. The fossil offered here is the exact specimen shown in the photographs, with scale cubes = 1cm to assist with sizing. It has been carefully selected and is presented exactly as found, with natural beauty and detail intact. All of our fossils are 100% Genuine Specimens and come with a Certificate of Authenticity. Whether you’re a seasoned fossil enthusiast, a palaeontologist, or searching for an eye-catching natural history display, this Notoceras heteromorph ammonite offers both scientific interest and visual appeal.
