Description
Fossil Identification
This listing presents a Promicroceras marstonense fossil multi block from Marston Magna in Somerset, UK. The specimen is identified with the geological and collecting terms Marston Marble, Obtusum Zone, Lower Lias and Lower Jurassic. It is an appealing piece for fossil collectors, ammonite enthusiasts, geological students and anyone interested in the palaeontology of southern England.
The product name identifies this as a multi-block ammonite fossil featuring Promicroceras marstonense. Its presentation makes it suitable for a fossil display, educational collection or geology-themed interior. The natural fossil material provides a direct connection with the ancient marine environments represented by Lower Jurassic rocks.
Geological Context
The Lower Jurassic forms part of the Mesozoic Era, a major interval in Earth history during which ammonites were widespread and diverse marine organisms. The Obtusum Zone is a biostratigraphic interval used by geologists to organise Lower Jurassic rocks and fossils according to their relative position in geological time. Identification by zone is particularly valuable to collectors because it links a fossil to a recognised part of the stratigraphic record.
Marston Magna, Somerset, is associated with important Lower Jurassic fossil collecting and geological study. The supplied identification records the material as Marston Marble, with the fossil placed within the Lower Lias and Obtusum Zone. These terms provide geological context for the specimen while retaining its connection to the Marston Magna locality.
Ammonite Interest
Ammonites were extinct marine cephalopods with coiled shells divided internally into chambers. Their shells are among the most recognisable fossils in geology, and their changing forms through time have made them especially useful in biostratigraphy. A named ammonite identification such as Promicroceras marstonense adds scientific and collecting interest by connecting the specimen with a particular fossil form and geological interval.
This fossil can be displayed as part of an ammonite collection, a Lower Jurassic assemblage or a broader UK geology cabinet. It also offers a useful conversation piece for discussing fossilisation, stratigraphy, ammonite evolution and the geological history of Somerset. The multi-block format gives the piece a distinctive natural presentation for collectors who appreciate locality-labelled material.
