Promicroceras marstonense Fossil Marston Magna Ammonites Multi Block Lower Lias, Obtusum Zone, Lower Jurassic

Description

Promicroceras marstonense Fossil

This fossil specimen is identified as Promicroceras marstonense and is presented in a multi-block format associated with Marston Magna ammonites. The specimen is connected with the Marston Marble, the Obtusum Zone and the Lower Lias of the Lower Jurassic. Its stated locality is Marston Magna, Somerset, UK, making it an appealing choice for fossil collectors, geology enthusiasts and anyone interested in the Jurassic history of southern Britain.

Geological Identification

Promicroceras marstonense is an ammonite identification. Ammonites were extinct marine cephalopods that lived in the oceans and are widely valued in palaeontology for their importance in interpreting Jurassic rocks. Their fossils are commonly used as biostratigraphic indicators because particular ammonite forms can help correlate sedimentary rocks deposited during specific intervals of geological time.

The Obtusum Zone is a recognised Lower Jurassic ammonite zone within the Lower Lias succession. The term “zone” refers to a biostratigraphic interval defined through fossil distribution, allowing geologists to compare rock sequences and fossil-bearing horizons. The supplied association with the Marston Marble and the Obtusum Zone gives this specimen a specific geological context beyond a general Jurassic identification.

Locality and Collector Interest

Marston Magna in Somerset, UK, is the stated locality for this fossil. Somerset fossils are of interest to collectors because they document the region’s ancient marine environments and its place within the geological history of the Lower Jurassic. A specimen labelled with its locality, stratigraphic association and ammonite identification can be a useful addition to a personal fossil collection, educational display or geology-themed interior arrangement.

The multi-block presentation provides a distinctive format for display and study. It can be used as a conversation piece while also offering an opportunity to explore how fossil material is associated with the surrounding geological setting. The named identification and stratigraphic information make it suitable for collectors who value geological context as well as the visual character of a natural fossil specimen.
