Description
Beudanticeras (Beudanticeras) newtoni Fossil Ammonite with Suture Patterns
This is a genuine Beudanticeras (Beudanticeras) newtoni ammonite fossil from the Gault Clay Formation of Folkestone, Kent, United Kingdom. Dating to the Aptian stage of the Early Cretaceous Period (approximately 125–113 million years ago), this specimen is a superb example of an important British ammonite species. It is particularly notable for its clearly preserved suture patterns, which highlight the intricate internal structure of the ammonite shell.
All of our fossils are 100% genuine specimens and are supplied with a Certificate of Authenticity. The photographs show the exact specimen you will receive, with a 1 cm scale cube and rule squares included for accurate sizing.
Geological Context and Age
The fossil comes from the Gault Clay Formation, one of the most famous Lower Cretaceous deposits in Europe. These clays were laid down in a shallow sea connected to the Tethys Ocean during the Aptian–Albian stages. At Folkestone, the exposure of these deposits along the coastline has made the site world-renowned among collectors and researchers.
The Aptian stage marks a significant evolutionary interval in ammonite history, when many new genera and species emerged. Beudanticeras newtoni is particularly important, as its distribution helps refine the stratigraphy of the Early Cretaceous.
Morphology and Distinctive Features
Beudanticeras newtoni belongs to the family Desmoceratidae, within the superfamily Desmoceratoidea of the order Ammonitida. It is typically identified by its moderately involute, discoidal shell, with gently rounded whorls and fine ribbing. Unlike heavily ornamented ammonites, Beudanticeras displays a more streamlined form, reflecting adaptations for active swimming in open marine environments.
The specimen offered here is distinguished by its visible suture patterns, which are the complex, leaf-like lines formed where the internal chamber walls met the shell wall. In Beudanticeras, these sutures are moderately elaborate, combining functional strength with an aesthetic beauty that appeals to collectors.
Scientific Importance
Beudanticeras newtoni is a significant ammonite in biostratigraphy, serving as an index fossil for parts of the Aptian stage. Its recognisable features allow geologists to correlate Gault Clay deposits across southern England with other Lower Cretaceous sites worldwide.
The presence of suture patterns adds to the scientific value, as these structures help palaeontologists better understand ammonite taxonomy and evolutionary pathways. They also demonstrate the internal complexity of ammonites, which contributed to their buoyancy control and ecological success.
Collector and Display Value
This Beudanticeras newtoni ammonite fossil with suture patterns from Folkestone is both scientifically valuable and highly decorative. The exposed sutures enhance the fossil’s natural beauty, making it a standout specimen for any collection. Ammonites from the Gault Clay are highly sought after due to their quality preservation and their importance to Early Cretaceous geology.
Whether displayed as a centrepiece in a fossil collection, used as a teaching specimen, or admired for its natural aesthetic, this ammonite is a striking piece of Britain’s deep geological history.
