Description
Promicroceras marstonense Fossil
This fossil multi block features Promicroceras marstonense ammonites from Marston Magna in Somerset, UK. The specimen is identified as Marston Marble from the Obtusum Zone of the Lower Lias, within the Lower Jurassic. Its combination of named fossil identification, geological zone and English locality makes it an appealing piece for fossil collectors, geology enthusiasts, educators and anyone interested in Jurassic marine life.
Geological Identification
Promicroceras marstonense is an ammonite fossil associated with the Lower Jurassic. Ammonites were extinct marine cephalopods that lived in the ancient seas and developed distinctive coiled shells. Their fossilised shells are especially valued by collectors because ammonites are important index fossils, helping geologists compare the relative ages of sedimentary rocks and recognise particular intervals in the Jurassic geological record.
This specimen is associated with the Obtusum Zone, a recognised biostratigraphic interval within the Lower Lias. The Lower Lias forms part of the Lower Jurassic succession and is well known for marine fossils preserved in sedimentary rocks. Marston Marble is the supplied geological material designation for this fossil, connecting the specimen with the Marston Magna area of Somerset.
Locality and Collector Interest
The stated locality is Marston Magna, Somerset, UK. Fossils from named British localities are popular with collectors because they provide a direct connection to the geological history of a particular region. Somerset has a strong association with Jurassic geology, and this Marston Magna specimen offers an attractive way to explore the fossil record of southern England.
The Promicroceras marstonense identification and Obtusum Zone designation provide useful display and study information. This makes the piece suitable for a personal fossil cabinet, classroom handling collection, geological display or educational workspace. It can also serve as an interesting gift for anyone fascinated by ammonites, Jurassic palaeontology or British geology.
Specimen Format and Photographs
This item is supplied as a fossil multi block. Full sizing is shown in the photographs. The photograph shows the actual specimen you will receive. Please review the images carefully for the displayed appearance, arrangement and visible fossil detail before purchasing.
Certificate of Authenticity
This Fossil is a genuine specimen and Includes a Certificate of Authenticity lifetime guarantee generic card.
The certificate wording is included to support the specimen’s presentation as a genuine fossil. Alongside the geological identification, locality and stratigraphic information, it provides useful reference details for collectors who wish to catalogue their material clearly and consistently.
Display and Educational Use
The specimen is well suited to fossil displays focused on ammonites, the Lower Jurassic, British geology or the fossil-bearing rocks of Somerset. It can be displayed as part of a collection of Jurassic fossils or used to introduce topics such as marine palaeontology, fossilisation, stratigraphy and biostratigraphy. The named Promicroceras marstonense identification also makes it a distinctive addition for collectors seeking a specifically identified ammonite rather than an unlabelled fossil example.
