Description
Promicroceras marstonense Fossil
This collectible fossil features Promicroceras marstonense, an ammonite identification associated with Marston Marble, the Obtusum Zone and the Lower Lias of the Lower Jurassic. Presented as a multi-block ammonite fossil, it is a distinctive addition to a fossil collection, geological display or natural history cabinet.
Geological Identification
Promicroceras marstonense belongs to the ammonites, an extinct group of marine cephalopods that lived in the world’s ancient seas. Ammonites are especially valued by collectors because their coiled shells provide an engaging link between fossil morphology, Jurassic marine life and the study of geological time.
The specimen is identified with the Obtusum Zone, a biostratigraphic interval within the Lower Lias. Biozones are used by palaeontologists and geologists to organise rocks and fossils according to their relative position in the geological record. The Lower Lias forms part of the Lower Jurassic, making this fossil relevant to Jurassic geology and the study of early Jurassic marine deposits.
Marston Marble and Locality
This fossil is associated with Marston Marble and Marston Magna, Somerset, UK. Marston Magna is recognised in the supplied identification as the locality connected with this ammonite material. The combination of Promicroceras marstonense, Marston Marble, the Obtusum Zone and the Lower Lias gives this specimen strong appeal for collectors who focus on British fossils, Jurassic ammonites or Somerset geological material.
Collector and Display Appeal
The multi-block format provides an unusual presentation for an ammonite fossil and makes it suitable for display among other Jurassic fossils, British geological specimens and palaeontological collectables. It can be used as a conversation piece in a home collection, classroom display, geology study area or natural history presentation.
The fossil identification also makes this piece useful for educational interest. It can help illustrate how ammonites are used in stratigraphy, how fossil-bearing geological units are named and how locality, zone and geological age work together to describe a specimen. Collectors may also appreciate the connection between a named ammonite species and a specific Jurassic biozone.
