Description
Fossil Identification
This listing features a Promicroceras marstonense fossil presented as a multi-block ammonite specimen. The identification is associated with Marston Magna, Somerset, UK, and the specimen is described within the Marston Marble, Obtusum Zone, Lower Lias and Lower Jurassic. These details make it an appealing addition to a fossil collection focused on ammonites, Jurassic palaeontology and the geological history of Britain.
The name Promicroceras marstonense identifies the ammonite represented by this fossil. Ammonites are extinct marine cephalopods recognised for their coiled shells and are among the most useful fossils for understanding and correlating sedimentary rocks. Their occurrence in Jurassic strata is of particular interest to collectors because ammonites can be linked with specific geological intervals and biozones.
Geological Interest
The Lower Jurassic was a significant period in the history of marine life, when seas covered parts of what is now the United Kingdom. Fossils from Lower Jurassic rocks are widely collected for their value in studying ancient marine environments, changing faunas and the succession of ammonite forms through geological time.
The Obtusum Zone is a recognised Lower Jurassic ammonite biozone. Biozones provide a framework for comparing fossil-bearing rocks and are especially important in ammonite palaeontology, where successive forms can help distinguish different intervals of geological time. The reference to the Marston Marble places this specimen within a named geological context associated with the Marston Magna area.
Specimen Presentation
This is a multi-block fossil specimen, making it suitable for collectors who enjoy specimens with a natural geological presentation rather than an isolated fossil removed from its surrounding material. The supplied identification and locality provide useful context for display, cataloguing and further study. It can be displayed as part of an ammonite collection, a Lower Jurassic fossil group or a broader geological collection featuring British material.

Collector and Gift Appeal
Promicroceras marstonense is a distinctive choice for collectors interested in named ammonites, Jurassic fossils and British geological localities. Its combination of fossil identification, Marston Magna locality, Marston Marble context and Obtusum Zone association gives it strong educational and display appeal. It may suit an experienced fossil collector, a student of geology, a natural history enthusiast or anyone building a themed collection of Lower Jurassic ammonites.
