Description
Fossil Identification
This listing features a Promicroceras marstonense fossil presented as a multi block of Marston Magna ammonites. The specimen is identified with the Marston Marble, the Obtusum Zone, the Lower Lias and the Lower Jurassic. It is associated with Marston Magna in Somerset, UK, making it a distinctive choice for collectors interested in British ammonites, Jurassic geology and historically important fossil localities.
Geological Context
The Lower Jurassic forms part of the Jurassic Period, an interval widely recognised for its rich marine fossil record. Ammonites are extinct, coiled marine cephalopods whose fossilised shells are important to palaeontology and biostratigraphy. Their evolution through successive rock layers allows particular forms and zones to be used when studying the relative ages of sedimentary deposits.
The Obtusum Zone is a recognised Lower Jurassic ammonite biozone. The association of this fossil with the Marston Marble and the Obtusum Zone provides useful geological context for collectors who document fossils by formation, stage and zone. The Lower Lias is especially well known for marine fossils preserved in rocks deposited during the early Jurassic, and the Marston Magna locality is a notable part of the Somerset fossil record.
Collector Interest
Promicroceras marstonense is an appealing addition to an ammonite collection because it combines a named fossil identification with specific British geological information. The multi-block presentation offers an interesting specimen format for display, study and comparison with other Jurassic ammonites. It is suitable for fossil collectors, geology enthusiasts, palaeontology students, educational displays and anyone interested in the Lower Jurassic rocks of southern England.
The specimen’s identification, geological zone and locality make it particularly relevant to collections organised around British fossils, Lower Lias material, Jurassic ammonites or stratigraphically documented specimens. It can also complement educational resources focused on extinct marine life, ammonite evolution, fossil preservation and the use of fossils in geological correlation.
Locality and Material Information
The fossil is identified with Marston Magna, Somerset, UK, and the Marston Marble. Its stated geological association is the Obtusum Zone of the Lower Lias within the Lower Jurassic. The supplied product name describes the item as a Promicroceras marstonense fossil Marston Magna ammonites multi block.
