Description
Promicroceras marstonense Fossil Ammonite
This polished sliced fossil slab features Promicroceras marstonense, an ammonite identified with Marston Magna, Somerset, UK. The specimen is associated with Marston Marble and the Obtusum Zone of the Lower Lias, within the Lower Jurassic. Its polished slab presentation makes it suitable for fossil collectors, geology enthusiasts, educational displays and natural history interiors.
Identification and Geological Context
Promicroceras marstonense is a named ammonite fossil from the Lower Jurassic. Ammonites were extinct marine cephalopods with coiled shells, and their fossils are widely valued for their importance in understanding ancient marine environments and for their use in geological correlation. The Lower Lias represents an important interval of Jurassic geology, and the Obtusum Zone provides a more specific biostratigraphic context for this fossil identification.
The reference to Marston Marble connects this specimen with the Marston Magna area of Somerset. Marston Magna is recognised among fossil localities associated with Lower Jurassic material, making this specimen an appealing choice for collectors who value both taxonomic identification and geological locality information. The combination of species name, locality, geological unit and zone gives the piece strong educational and display interest.
Specimen Presentation
The fossil has been sliced and polished to create a clean display surface while retaining the character of the natural material. As a polished slab, it can be displayed in a fossil cabinet, geological collection, study, office, classroom or home interior. It also makes a useful addition to collections focused on ammonites, Jurassic fossils, Somerset geology or British palaeontology.
This specimen is described as high grade in the product name and is presented as a finished polished fossil item rather than an unprepared field piece. The natural fossil content and geological setting provide an opportunity to explore ammonite morphology, Jurassic marine life and the role of zonal fossil identification in geology.
