Description

Promicroceras marstonense Fossil

This fossil listing features a Promicroceras marstonense ammonite multi block associated with Marston Magna, Somerset, UK. The specimen is identified as Marston Marble from the Obtusum Zone of the Lower Lias, within the Lower Jurassic. It is a distinctive geological and palaeontological item for fossil collectors, ammonite enthusiasts, geology students, and anyone interested in the Jurassic rocks of southern England.

Identification and Geological Context

Promicroceras marstonense is an ammonite fossil identification. Ammonites were extinct marine cephalopods that lived in the ancient seas and produced coiled, chambered shells. Their fossilised shells are especially important in geology because ammonites can be used to compare and date Jurassic rock sequences through biostratigraphy.

The Lower Lias belongs to the Lower Jurassic and contains important marine fossil records from the Jurassic seas. The Obtusum Zone is a recognised ammonite biozone within the Lower Lias. This zonal information gives the specimen useful geological context and connects it with the detailed stratigraphic study of Jurassic rocks. The named Marston Marble association further links this fossil to the Marston Magna area of Somerset.
