Identification and Geological Context

This fossil is identified as Promicroceras marstonense and is presented as an ammonites multi block associated with Marston Magna, Somerset, UK. The specimen is described as Marston Marble, within the Obtusum Zone of the Lower Lias and Lower Jurassic. These geological terms provide important context for collectors interested in the stratigraphic setting and historical fossil-bearing localities of southern Britain.

Ammonites were extinct marine cephalopods with coiled shells divided internally into chambers. They lived in the sea and are widely valued by collectors because their chambered shells preserve distinctive shapes and patterns that can assist with identification. Promicroceras is a Jurassic ammonite name, and Promicroceras marstonense represents the specific identification supplied for this fossil.
