Promicroceras marstonense Fossil
This collectible fossil features Promicroceras marstonense ammonites in a multi-block specimen from Marston Magna, Somerset, UK. The material is identified as Marston Marble and is associated with the Obtusum Zone of the Lower Lias, within the Lower Jurassic. Its clearly stated geological context makes it an appealing addition to fossil collections, educational displays and natural history interiors.
Identification and Geological Context
Promicroceras marstonense is an ammonite fossil identification associated with the Lower Jurassic. Ammonites were extinct marine cephalopods with coiled shells, and their fossils are widely valued for their importance in geological study and biostratigraphy. The Lower Jurassic forms part of the Mesozoic Era, and ammonites from this interval are especially relevant to collectors interested in the history of marine life and Jurassic geology.
This specimen is connected specifically with the Obtusum Zone and the Lower Lias. A named zone provides useful geological context by placing the fossil within a recognised interval of the Jurassic succession. The locality of Marston Magna, Somerset, UK, adds regional interest for collectors who focus on British fossils, Somerset geology or Lower Jurassic material.
Marston Marble Multi-Block Specimen
The fossil is presented as a Marston Marble multi-block specimen. This format offers a distinctive display piece for a cabinet, study, classroom collection or geological teaching display. The product name identifies the specimen as containing Promicroceras marstonense ammonites, while the supplied geological details connect it with the Marston Marble, Lower Lias and Obtusum Zone.
Its combination of a named ammonite identification, a defined Jurassic geological interval and a British locality makes it suitable for fossil enthusiasts, ammonite collectors, geology students and anyone building a themed natural history display. It can also serve as an accessible conversation piece for explaining how fossil identifications are linked to geological zones and localities.
