Description
Promicroceras marstonense Fossil
This collectible fossil is identified as Promicroceras marstonense and presented as a multi-block ammonite specimen from Marston Magna, Somerset, UK. It is associated with the Marston Marble, the Obtusum Zone and the Lower Lias of the Lower Jurassic. The combination of a named ammonite identification, a defined Jurassic zone and a recognised Somerset locality makes this an appealing addition to fossil collections, geological displays and educational cabinets.
Geological Identification
Promicroceras marstonense belongs to the ammonites, an extinct group of marine cephalopods that are especially important in the study of Jurassic rocks. Ammonites are commonly used by geologists to compare the relative ages of sedimentary strata because particular forms can be associated with specific intervals of geological time. This specimen is identified specifically as Promicroceras marstonense rather than being offered simply as an unidentified ammonite.
The Lower Lias represents rocks from the early part of the Jurassic Period. The Obtusum Zone provides a more precise biostratigraphic context within the Lower Lias, making the identification relevant to collectors interested in fossil zonation and the geological history of southern England. Marston Marble and Marston Magna provide an important locality context for this fossil material in Somerset.
Specimen Presentation
This is a multi-block fossil presentation, offering a distinctive format for display and study. The specimen is suitable for collectors of ammonites, Jurassic fossils, British fossils and Somerset geological material. It can be displayed as part of a natural history collection or used as a conversation piece when discussing ammonite evolution, Jurassic stratigraphy and fossil-bearing rocks from the UK.
The locality and zonal information add educational value for anyone researching the Lower Jurassic, the Lower Lias or the fossiliferous geology of Marston Magna. Its named identification also makes it useful for comparison with other ammonites from the Jurassic and with specimens from different stratigraphic zones.

Collector and Display Uses
This Promicroceras marstonense fossil is well suited to ammonite collectors, enthusiasts of Lower Jurassic palaeontology, geology students, teachers and museums or display spaces focused on British natural history. It brings together a formal fossil identification, the Marston Magna locality, the Marston Marble context and the Obtusum Zone within one displayable specimen.
Its subject matter supports research and discussion about Jurassic marine life, ammonite biostratigraphy and the use of fossil zones in geological interpretation. The specimen can be incorporated into a collection organised by fossil group, geological period, locality or stratigraphic zone.
