Description
Promicroceras marstonense Fossil
This genuine fossil specimen is identified as Promicroceras marstonense, an ammonite presented as a sliced, polished slab. The specimen is associated with Marston Magna, Somerset, UK, and is described as Marston Marble from the Obtusum Zone of the Lower Lias, within the Lower Jurassic. Its polished surface displays the fossil in an attractive presentation suitable for fossil collectors, geological displays and educational collections.
Geological Identification
Promicroceras marstonense is an ammonite identification associated with Lower Jurassic rocks. Ammonites were extinct marine cephalopods with coiled shells, and their fossilised shells are valued by collectors for their distinctive chambered forms and importance in geological study. The supplied identification places this specimen within the Obtusum Zone, a recognised biostratigraphic interval used to help relate Lower Jurassic rocks and fossils to a particular position in geological time.
The Lower Lias is a Lower Jurassic geological unit known for marine fossil material, including ammonites. Ammonites are especially useful in stratigraphy because different forms occurred during successive intervals, allowing palaeontologists and geologists to compare rock sequences and fossil assemblages. The identification Promicroceras marstonense therefore gives this specimen interest beyond its visual appeal, linking it to the study of Jurassic marine life and biozonation.
Marston Magna Somerset Fossil
