Description
Fossil Identification
This listing features a Promicroceras marstonense fossil ammonite presented as a multi-block specimen. The identification is associated with Marston Marble, the Obtusum Zone, the Lower Lias and the Lower Jurassic. It is listed from Marston Magna, Somerset, UK, making it an appealing choice for collectors interested in British Jurassic fossils, ammonites and regional geology.
The name Promicroceras marstonense identifies the fossil as an ammonite within the wider fossil record of Jurassic marine life. Ammonites were extinct marine cephalopods with chambered shells, and their fossils are widely studied because their changing forms help document geological time. This specimen offers a tangible connection to the Lower Jurassic and to the ammonite-bearing geology associated with Somerset.
Geological Context
The Lower Jurassic forms an important part of the Jurassic geological record. The Lower Lias is a traditional geological term used for Lower Jurassic strata, particularly in the British geological context. The Obtusum Zone is a biostratigraphic interval used by geologists to organise and compare Lower Jurassic rocks and fossils. Its inclusion in the identification gives this specimen added interest for collectors who value precise geological context alongside fossil form.
Marston Marble is included in the identification supplied for this specimen, together with the Marston Magna locality in Somerset, UK. These details connect the fossil to a specific British collecting and geological tradition without relying solely on the appearance of the ammonite. The multi-block format makes the piece suitable for fossil displays, educational collections, geology cabinets and anyone building a focused selection of Jurassic ammonites.
Collector and Display Interest
This Promicroceras marstonense fossil is suited to collectors seeking an identified Lower Jurassic ammonite with named zone and locality information. It can be displayed as part of an ammonite collection, a British fossil assemblage or a wider study of Jurassic palaeontology. The multi-block presentation provides a distinctive format for a geological display and allows the specimen to be considered in relation to the supplied Marston Marble identification.
The specimen may also be useful as an educational example when discussing ammonites, biostratigraphy, the Lower Jurassic and the use of named geological zones. Its combination of fossil identification, geological terminology and Somerset location gives it interest beyond a generic fossil ornament or decorative object.
