Promicroceras marstonense Fossil Ammonites Marston Marble Lower Jurassic UK

Description

Fossil Identification

This listing features a Promicroceras marstonense fossil presented as a multi-block ammonite specimen. The identification is associated with Marston Marble, the Obtusum Zone and the Lower Lias of the Lower Jurassic. The recorded locality is Marston Magna, Somerset, UK, making this an appealing geological specimen for collectors interested in British fossils, ammonites and Lower Jurassic palaeontology.

Promicroceras marstonense is an ammonite identification. Ammonites were extinct marine cephalopods with coiled shells, and their fossils are widely valued both for their distinctive form and for their importance in geological correlation. The ammonite zones of the Lower Jurassic provide a useful framework for understanding the relative sequence of marine rocks and fossil assemblages through this part of the Jurassic Period.

Geological Context

The Lower Lias is a Lower Jurassic geological unit known for marine fossil content and ammonites. The Obtusum Zone is a biostratigraphic interval used by palaeontologists and geologists to place fossil-bearing rocks in their relative position within the Lower Jurassic succession. The association with the Obtusum Zone adds specialist interest for collectors who study ammonite zonation, stratigraphy and the fossil record of southern Britain.

Marston Marble is included in the supplied identification and geological description. The named locality, Marston Magna in Somerset, UK, gives the specimen a clear British geological connection. Somerset fossils are collected and studied for their contribution to understanding the marine environments and changing life forms represented in Jurassic rocks.

Collector Interest

This Promicroceras marstonense specimen is suited to fossil collectors, ammonite enthusiasts, geology students, educational displays and anyone interested in the Lower Jurassic of the United Kingdom. Its combination of a named ammonite identification, a defined stratigraphic zone and a stated Somerset locality makes it particularly relevant to collections organised by genus, geological age, formation or biozone.

The multi-block format gives the piece a distinctive presentation for a display cabinet, study shelf or teaching collection. It can be used as a conversation piece when discussing ammonites, Jurassic marine ecosystems, biostratigraphy and the way fossil zones help geologists compare rocks from different locations. The specimen also offers an opportunity to explore how fossil identification combines the visible features of an ammonite with geological information such as locality and stratigraphic position.
