Description
Fossil Identification
This listing presents a Promicroceras marstonense fossil ammonite multi block from Marston Magna, Somerset, UK. The specimen is identified as Marston Marble, Lower Lias, Lower Jurassic, and is associated with the Obtusum Zone. These details make it an appealing addition to a fossil collection focused on ammonites, Jurassic geology, or British fossil localities.
Geological Context
The Lower Jurassic forms part of the Mesozoic Era and is widely recognised for its fossil-rich marine rocks. During this period, ammonites were important marine animals whose fossilised shells can help document ancient environments and geological time. The Obtusum Zone is a defined biostratigraphic interval within the Lower Jurassic, providing useful geological context for fossils assigned to this part of the sequence.
Marston Marble is associated with the Marston Magna area of Somerset and is represented here as the material containing the Promicroceras marstonense ammonites. The Lower Lias designation places this fossil within an important Lower Jurassic geological sequence. Together, the identification, zone and locality provide a strong connection to the stratigraphy of southern England.
Collector and Display Interest
Promicroceras marstonense is a valuable identification for collectors interested in named ammonite fossils rather than unidentified fragments. The multi-block format offers a natural display piece for a fossil cabinet, geological study area, classroom collection or home office. It can also serve as an educational example for exploring ammonite palaeontology, Jurassic stratigraphy and the relationship between fossil specimens and their geological context.
This fossil is suited to collectors who value documented locality information and named Lower Jurassic material. Its association with Marston Magna, Somerset, together with the Marston Marble, Lower Lias and Obtusum Zone terminology, gives the piece useful context for labelling, cataloguing and display.
