Description
Fossil Identification
This listing is for a Promicroceras marstonense fossil ammonite multi block associated with Marston Magna, Somerset, UK. The specimen is described as Marston Marble, Obtusum Zone, Lower Lias, Lower Jurassic, providing useful geological and chronological information for collectors of ammonites, British fossils and Lower Jurassic material.
The identification Promicroceras marstonense is the key feature of this fossil. Promicroceras is an ammonite name, placing this specimen within the extinct marine cephalopods commonly recognised by their coiled fossil shells. The multi-block format makes it a distinctive addition to a fossil collection, geological display or educational specimen selection.
Geological Context
The Lower Jurassic forms an important part of the Jurassic Period and is well known for marine fossil assemblages. Ammonites are especially valued in Jurassic geology because their changing forms can assist with the subdivision and correlation of sedimentary rocks. The Obtusum Zone is an ammonite biozone within the Lower Jurassic sequence, while Lower Lias is a traditional geological term used for Lower Jurassic strata.
The supplied geological designation also includes Marston Marble. In this listing, the specimen is presented with the locality and geological terminology provided for the fossil: Marston Magna, Somerset, UK; Marston Marble; Obtusum Zone; Lower Lias; and Lower Jurassic. These details make the piece relevant to collectors interested in British palaeontology, ammonite biozones and the geological history of Somerset.
Collector and Display Appeal
A Promicroceras marstonense fossil offers an opportunity to own a specimen connected with a specific ammonite identification and a defined Lower Jurassic zone. The multi-block presentation can be displayed as part of an ammonite collection, fossil cabinet, geology classroom, museum-style arrangement or natural-history themed interior. It is also suitable for collectors who focus on British localities, Jurassic fossils, Lias material or stratigraphically documented specimens.
The combination of fossil identification, locality, zone and geological age gives this piece strong educational appeal. It can help illustrate how fossils are catalogued using a combination of morphology, geological interval and collecting locality, while also serving as an attractive conversation piece for anyone interested in palaeontology and Earth history.
