Description

Identification and Geological Context

This listing is for a Promicroceras marstonense fossil multi block from Marston Magna, Somerset, UK. The specimen is identified with the Marston Marble, the Obtusum Zone and the Lower Lias, placing it within the Lower Jurassic. It is described as an ammonite fossil and represents an attractive subject for collectors interested in British geology, Jurassic palaeontology and ammonite identification.

Promicroceras marstonense is an ammonite identification associated with the Lower Jurassic record. Ammonites were extinct marine cephalopods with chambered shells, and their fossils are especially important in stratigraphy because particular forms can help distinguish successive intervals of geological time. The Obtusum Zone is a biostratigraphic interval within the Lower Lias, making the stated zone an important part of the specimen’s geological information.

Specimen Details

The specimen is presented as a multi block, offering a naturally collected fossil format for display and study. Its stated location is Marston Magna, Somerset, UK, and the associated geological designation is Marston Marble. The combination of a named ammonite, a British locality, a recognised stratigraphic zone and Lower Jurassic context gives this piece strong appeal for fossil collectors, ammonite enthusiasts, geology students and anyone building a collection focused on the Jurassic rocks of the United Kingdom.

Marston Magna is particularly associated with the fossil-bearing geological material identified here as Marston Marble. The supplied identification, locality and stratigraphic information should be retained with the specimen as part of its display or collection records. It can be displayed as a standalone geological specimen or included within a wider collection of Lower Jurassic fossils, British ammonites and stratigraphically identified material.

Collector and Display Interest

This Promicroceras marstonense fossil is suited to collectors who value named specimens with locality and zone information. The multi-block presentation provides a distinctive format compared with a single isolated fossil and makes the piece suitable for a cabinet, study area, educational display or geology-themed interior. It also offers an opportunity to discuss ammonite morphology, Jurassic marine environments and the use of fossil zones in geological correlation without requiring the specimen to be treated as a generic decorative stone.
