Description
Fossil Identification
This listing features a Promicroceras marstonense fossil presented as a multi-block ammonite specimen. It is identified as belonging to the ammonite genus and species Promicroceras marstonense, making it a distinctive addition for collectors interested in Lower Jurassic fossils, ammonites and regional British palaeontology.
The specimen is associated with Marston Magna in Somerset, UK. Its geological identification is given as Marston Marble, within the Obtusum Zone of the Lower Lias and Lower Jurassic. These details provide useful context for collectors who catalogue fossils by locality, geological unit and biozone.
Geological Context
The Lower Jurassic forms an important part of the Jurassic fossil record and is especially well known for marine fossils, including ammonites. Ammonites were extinct marine cephalopods with coiled shells, and their evolutionary changes through geological time make them valuable to palaeontological study and stratigraphic comparison. The presence of a named zone such as the Obtusum Zone adds a more specific geological framework to the specimen’s identification.
Marston Marble is the named geological material associated with this fossil, while the Marston Magna locality in Somerset provides its regional collecting context. The combination of species identification, locality, formation-related terminology and biozone makes this specimen suitable for an organised fossil collection, teaching display or geology-themed presentation.
Collector Appeal
Promicroceras marstonense is an appealing choice for collectors seeking a named Lower Jurassic ammonite fossil rather than an unidentified shell fragment. The multi-block presentation offers an attractive way to display the specimen while retaining its connection to the geological material in which it occurs. It can be used in a collection focused on British fossils, Somerset geology, Lower Lias material, Jurassic ammonites or stratigraphically documented specimens.
This fossil may also be of interest to students, educators and enthusiasts exploring how ammonites are used in geological classification. The supplied identification and geological terminology allow the specimen to be catalogued with its species name, locality, geological unit and zone.
