Description
Stephanoceras Ammonite Fossil
This fossil is identified as Stephanoceras sp., an ammonite fossil from the Jurassic Period. The specimen is associated with the Bajocian, the Middle Jurassic stage, and is recorded from the Ovalis Zone of the Inferior Oolite. Its stated locality is Sherborne, Dorset, UK, making it an appealing addition for collectors of British Jurassic fossils, ammonites and stratigraphic specimens.
Geological Identification
The identification Stephanoceras sp. places the specimen within the Stephanoceras genus. The abbreviation “sp.” indicates that the specimen is assigned to the genus without a species-level name being specified. Stephanoceras is an ammonite genus, and ammonites were extinct marine cephalopod molluscs with coiled shells. Their shells and distribution through geological time make ammonites important to fossil collectors and useful in understanding Jurassic rocks and biozones.
The Bajocian forms part of the Middle Jurassic and is well known for ammonite-bearing marine deposits. The Inferior Oolite is a Jurassic geological unit in England, while the Ovalis Zone provides a more specific biostratigraphic placement within the sequence. These geological details make the specimen suitable for collectors interested not only in the visual appeal of ammonites, but also in Jurassic stratigraphy, zonation and the fossil record of southern Britain.
Locality and Collection
The recorded locality for this fossil is Sherborne, Dorset, UK. Dorset is internationally recognised for its rich Jurassic fossil heritage, and specimens from this region are popular with collectors, students, educators and anyone interested in the geology of the British Isles.
