Description
Fossil Identification
This listing is for a Promicroceras marstonense fossil multi block from Marston Marble. The specimen is identified as an ammonite from the Obtusum Zone of the Lower Lias, part of the Lower Jurassic. Its multiple-block format makes it an attractive choice for collectors interested in ammonites, Jurassic palaeontology and historically important fossil-bearing materials.
Geological Context
The Lower Lias represents an important part of the Lower Jurassic fossil record. Ammonites from this interval are especially valued because their coiled shells can provide useful information about the marine environments and geological succession in which they were preserved. The Obtusum Zone is a recognised biostratigraphic interval within the Lower Lias, allowing fossils assigned to it to be placed within a more specific part of Jurassic geological time.
Promicroceras marstonense is presented here as a named ammonite fossil associated with the Marston Marble of Marston Magna, Somerset, UK. The locality gives this piece strong regional interest for collectors of Somerset fossils and Lower Jurassic material. Marston Magna specimens are associated with the local geological heritage of the area and are sought after for their connection to the Jurassic rocks of southern England.
Specimen Format and Display
This is a multi-block fossil specimen, offering an interesting presentation for a fossil cabinet, geology collection, educational display or natural-history themed interior. The visible fossil material can be examined as part of a broader study of Jurassic ammonites and the fossil record of the Lower Lias. The specimen may also appeal to collectors who focus on British fossils, ammonites, stratigraphy or regional geology.

Collector and Educational Interest
Ammonites were marine cephalopods with coiled shells and are among the best-known fossils from the Mesozoic Era. Their abundance, recognisable form and use in biostratigraphy have made them important to both professional palaeontology and private fossil collecting. A named Lower Jurassic ammonite from a defined zone and locality can provide an engaging way to explore geological time, fossil classification and the changing marine environments of the Jurassic seas.
The combination of Promicroceras marstonense identification, Marston Marble association, Marston Magna locality, Obtusum Zone placement and Lower Jurassic age makes this multi-block fossil suitable for collectors seeking a distinctive British ammonite specimen with clear geological context.
