Description
Promicroceras marstonense Fossil
This fossil multi block presents Promicroceras marstonense, an ammonite identification associated with Marston Magna in Somerset, UK. It is listed from the Marston Marble, within the Obtusum Zone of the Lower Lias, a geological unit belonging to the Lower Jurassic. The combination of named fossil identification, geological zone and locality makes this an appealing specimen for collectors interested in Jurassic palaeontology and British fossil material.
Geological Identification
Promicroceras marstonense is an ammonite fossil. Ammonites were extinct marine cephalopods with coiled shells and are among the most useful fossils for understanding the Jurassic marine record. Their distribution through successive geological intervals has made ammonites important to biostratigraphy, the study of rock layers and fossil zones used to correlate deposits across different areas.
The Obtusum Zone provides a more specific geological context within the Lower Lias. The Lower Lias forms part of the Lower Jurassic, an interval of Earth history known for extensive marine deposits and the preservation of ammonites and other marine fossils. This specimen is specifically associated with the Marston Marble and the Marston Magna area of Somerset, giving it a clear British geological setting.
Specimen Format and Collector Interest
The multi-block presentation is suited to fossil collectors who appreciate specimens connected to a defined locality and stratigraphic zone. The named identification and documented geological context can also make this piece a useful addition to a teaching collection, fossil display, or study of Lower Jurassic ammonites. It offers an opportunity to explore the relationship between fossil identification, geological formations and biozones without relying solely on a generic fossil label.
The Marston Magna association places the specimen within the fossil heritage of Somerset, UK. Its Lower Jurassic and Obtusum Zone designation adds further geological detail for collectors cataloguing specimens by age, zone or locality. It can be displayed as part of an ammonite collection or alongside other Jurassic fossils to illustrate the range of material found in marine sedimentary sequences.
