Product Identification
This collectible fossil is identified as Promicroceras marstonense and is presented as a fossil ammonite multi block. It is associated with Marston Marble and the Obtusum Zone of the Lower Lias, Lower Jurassic. The specimen is from Marston Magna, Somerset, UK, making it an appealing piece for fossil collectors, geology enthusiasts and anyone interested in the palaeontological heritage of southern Britain.
Geological Context
Promicroceras marstonense belongs to the ammonites, an extinct group of marine cephalopods that are especially valued by collectors for their distinctive fossilised shells and importance in Jurassic geology. Ammonites are widely used in the study of geological strata because their fossils can help relate rock sequences to particular intervals of geological time. The identification of this specimen places it within the Lower Jurassic Lower Lias and specifically the Obtusum Zone.
Marston Marble is the geological material associated with this fossil. Despite its name, the term is used in the local geological context for the stone from the Marston Magna area. The Somerset origin adds regional interest, while the Lower Jurassic setting connects the specimen with an important period in the development of marine fossil records. The stated zone and stratigraphic information make this a useful addition to a collection focused on ammonites, Jurassic fossils or British geology.
Collector Interest
The multi-block format gives this piece a distinctive presentation and makes it suitable for a display devoted to ammonites, stratigraphy or fossils from the United Kingdom. Promicroceras marstonense is a specific fossil identification rather than a generic ammonite label, providing added interest for collectors who catalogue specimens by genus, species, geological stage and biozone.
This fossil can be displayed as part of a natural history collection, used as an educational conversation piece or presented alongside other Lower Jurassic material. Its combination of named fossil identification, Marston Magna locality, Marston Marble association and Obtusum Zone placement offers several useful cataloguing details for collectors.
