Description
Fossil Identification
This listing is for a Promicroceras marstonense fossil preserved as an ammonites multi block from Marston Magna, Somerset, UK. The specimen is associated with Marston Marble and is identified from the Obtusum Zone of the Lower Lias, within the Lower Jurassic. Its named identification, geological context and locality make it a distinctive addition to a fossil collection focused on ammonites, Jurassic palaeontology or the geology of Somerset.
Geological Context
The Lower Lias belongs to the Lower Jurassic, an important interval in Earth history when marine environments supported diverse communities of ammonites and other organisms. The Obtusum Zone is a recognised biostratigraphic zone within the Lower Lias. Fossil zones such as this are used by geologists and palaeontologists to organise rocks and fossils according to their position in geological time and their characteristic fossil content.
Marston Magna, in Somerset, is associated with the geological material known as Marston Marble. This historical geological name is represented here in the specimen’s supplied identification as “Marston Marble”. The combination of locality, named material, stratigraphic zone and Lower Jurassic age provides useful collecting context for anyone interested in British fossils and the Jurassic rocks of southern England.
Collector Interest
Promicroceras marstonense is an ammonite fossil identification. Ammonites were extinct marine cephalopods with chambered shells, and their fossils are widely valued for both their scientific importance and their distinctive place in the fossil record. As a multi-block specimen, this piece offers an interesting format for display and study, while the named locality and geological zone add depth to its cataloguing information.
This fossil is suitable for collectors of Jurassic ammonites, British geology, Somerset fossils, Lower Lias material and scientifically labelled natural history specimens. It can also make an educational display piece for illustrating geological time, fossil identification and the use of stratigraphic zones in palaeontology. The supplied identification should be retained with the specimen for future reference and collection records.
