RARE TURRILITES SCHEUZERIANUS HETEROMORPH AMMONITE FROM SUSSEXThis listing offers a rare Turrilites scheuzerianus heteromorph fossil ammonite,
collected from Cenomanian chalk deposits in Sussex, United Kingdom. Dating to the Late Cretaceous Period, around 100–94 million years ago, this specimen is part of one of the most distinctive ammonite groups. Unlike typical planispiral ammonites, heteromorphs such as Turrilites developed striking turret-like shells that make them instantly recognisable and scientifically valuable.All of our fossils are 100% genuine specimens and are supplied with a Certificate of Authenticity. The fossil pictured is the exact specimen you will receive, with a 1cm scale cube and rule squares included for precise size reference. GEOLOGICAL AGE AND PROVENANCEThis ammonite originates from the Cenomanian Stage, the first stage of the Late Cretaceous. During this interval, Earth experienced some of the highest sea levels in its history. Warm, shallow epicontinental seas covered much of Europe, creating marine ecosystems rich in biodiversity.The chalk cliffs of Sussex form part of the famous White Chalk deposits, a globally recognised fossil-bearing formation. These deposits have yielded some of the most important ammonites for biostratigraphy, including Turrilites scheuzerianus, which is a defining species within the Cenomanian. Fossils from this locality are of great historical and scientific significance, making this specimen an exceptional addition to any collection. FOSSIL TYPE AND SCIENTIFIC CLASSIFICATION
• Genus: Turrilites
• Species: Turrilites scheuzerianus
• Order: Ammonitida
• Superfamily: Turrilitoidea
• Family: TurrilitidaeTurrilites scheuzerianus is an important index fossil for Cenomanian deposits. Its restricted stratigraphic range and distinctive morphology make it one of the key species used by geologists to identify and correlate Cenomanian rock layers across Europe. MORPHOLOGICAL FEATURESTurrilites scheuzerianus is notable for its distinctive coiling and ornamentation:
• Helicoidal Shell Growth: The shell grows in a tall, vertical spiral rather than a flat coil, giving the fossil a striking turret-like appearance.
• Strong Ribbing: Bold ribs run across the whorls, producing a sharply defined, sculptural texture.
• Tuberculation: Small nodes or tubercles often develop along the ribs, adding diagnostic ornamentation.
• Keel Formation: A keel may run along the venter, contributing to both hydrodynamic function and identification.These features not only distinguish the species from other Turrilites but also highlight the evolutionary experimentation of heteromorph ammonites. SCIENTIFIC AND COLLECTOR IMPORTANCETurrilites scheuzerianus plays an essential role in biostratigraphy, as it helps define ammonite biozones within the Cenomanian Stage. Its presence in chalk deposits allows geologists to precisely date and correlate strata across large regions.For collectors, Turrilites scheuzerianus is particularly desirable due to its rarity, unusual form, and scientific significance. Specimens from Sussex are especially prized, both for their provenance and for their connection to one of the most famous fossil-bearing regions in the world. DISPLAY AND EDUCATIONAL VALUEThis fossil was carefully chosen for its preservation and diagnostic features, making it an excellent specimen for both display and study. Its turret-like shell form and bold ornamentation create a visually striking piece that will stand out in any collection.Ideal for private collections, educational use, or museum exhibits, this rare Turrilites scheuzerianus ammonite from Sussex represents not only a fascinating evolutionary pathway within the ammonites but also a direct link to the shallow seas of the Cenomanian. It is a scientifically significant and aesthetically remarkable fossil that captures the diversity of life in the Cretaceous seas.
