Description
Fossil Identification
This listing presents a Promicroceras marstonense fossil ammonite in a sliced, polished slab format. The specimen is identified as Promicroceras marstonense and is associated with Marston Marble, the Obtusum Zone, the Lower Lias and the Lower Jurassic. Its polished slab presentation makes it a distinctive geological display piece for fossil collectors, ammonite enthusiasts and anyone interested in the Jurassic history of Britain.
Geological Context
The Lower Jurassic forms an important part of the Jurassic fossil record, and the Lower Lias is widely recognised for its marine fossil content. The Obtusum Zone is a biostratigraphic interval used by geologists to organise Lower Jurassic strata and correlate rocks of similar age. In this listing, the zone information is part of the supplied identification for the specimen.
Ammonites are extinct marine cephalopods known for their coiled shells and value in palaeontology. Because ammonite forms occur through successive geological intervals, they are frequently used as index fossils and as indicators of relative geological age. A sliced and polished ammonite slab offers a presentation suited to close viewing, collection display and geological study, while retaining the character of a genuine fossil specimen.
Locality and Material
The stated locality is Marston Magna, Somerset, UK. The product is identified as Marston Marble and is presented as a polished slab. Marston Magna material is of particular interest to collectors seeking British Jurassic fossils and specimens connected with the Somerset geological record. The combination of the Promicroceras marstonense identification, Marston Marble association and Obtusum Zone reference gives this piece strong appeal as a regionally specific Lower Jurassic fossil display.
Collector and Display Appeal
This high-grade polished fossil slab is suitable for a fossil cabinet, study collection, educational display or geology-themed interior. It can be appreciated as an identified ammonite fossil as well as a representative specimen connected with Lower Lias stratigraphy. The polished finish provides a clean presentation for viewing the specimen, while the sliced format gives it the character of a prepared geological specimen rather than an unworked field find.
The specimen is relevant to collectors of Promicroceras fossils, Lower Jurassic ammonites, Somerset fossils, British geology, Marston Marble and biostratigraphic material from the Obtusum Zone. It also makes an informative addition to collections focused on Jurassic marine life, ammonite diversity and the geological history of the United Kingdom.
