Description
Promicroceras marstonense Fossil
This multi-block fossil features Promicroceras marstonense ammonites from Marston Magna, Somerset, UK. The specimen is identified with the Marston Marble, Obtusum Zone, Lower Lias and Lower Jurassic. It is a distinctive addition for fossil collectors, ammonite enthusiasts, geology students, museum-style displays and anyone interested in the palaeontology of southern Britain.
Geological Identification
Promicroceras marstonense is an ammonite fossil associated with the Lower Jurassic. Ammonites were extinct marine cephalopods with coiled shells, and their fossils are especially valued by collectors because they can be studied in relation to geological age, changing marine environments and biostratigraphic zones. The Obtusum Zone provides a more specific geological context within the Lower Lias, while Marston Marble identifies the named geological material associated with this specimen.
The Lower Jurassic forms an important part of the early Jurassic geological record. Fossils from this interval are widely collected for their scientific and educational value, helping illustrate the diversity of ancient marine life and the succession of fossil-bearing rocks through geological time. This specimen’s identification as Promicroceras marstonense, together with its Marston Marble and Obtusum Zone details, gives it strong interest for collectors seeking a clearly labelled Lower Jurassic ammonite fossil.
Locality and Collector Appeal
The stated locality is Marston Magna, Somerset, UK. Marston Magna fossils are well known among collectors interested in British Jurassic geology, and this specimen offers a focused example for a regional fossil collection. Its multi-block format makes it suitable for display alongside other ammonites, Lower Lias fossils, Jurassic geological material or specimens from Somerset.
This fossil can be used as a conversation piece, educational display item or reference specimen for exploring ammonite identification and Jurassic stratigraphy. The named locality, geological material, zone and age provide useful information for arranging a themed collection or creating an informative cabinet display.
