Description
Promicroceras Calcite Ammonite Fossil
This Promicroceras Calcite Ammonite Fossil is a distinctive geological specimen associated with the Black Ven Marls of the Lower Lias. The recorded location is Black Ven, Lyme Regis, Dorset, UK, within the famous Jurassic Coast. With its named fossil identification, calcite composition and documented geological setting, it is a compelling addition to a fossil collection, natural history display or geology-focused gift selection.
Fossil Identification
Promicroceras is an ammonite fossil. Ammonites were extinct marine cephalopods whose shells commonly developed a coiled form and were divided internally by chambers. Their fossilised shells are important to palaeontology because ammonites can help illustrate ancient marine ecosystems and the changing history of life during the Mesozoic Era.
This specimen is identified specifically as Promicroceras and is presented as a calcite ammonite fossil. The combination of a recognised ammonite name and calcite material makes it suitable for collectors interested in fossil taxonomy, mineralised remains and the geological record of the Jurassic. It offers an accessible way to explore the relationship between palaeontology, stratigraphy and mineral preservation.
Geological Location and Stratum
The specimen is associated with the Black Ven Marls, Lower Lias, Jurassic Coast. Its recorded locality is Black Ven at Lyme Regis in Dorset, UK. The Jurassic Coast is internationally known for its exposed geological history and fossil-bearing coastal rocks. Lyme Regis is especially associated with fossil collecting and geological study, making specimens from this area popular with collectors and enthusiasts of British palaeontology.
The term “Lower Lias” refers to a recognised geological succession within the Jurassic rock record. Marls are sedimentary rocks formed from a mixture of clay-rich and carbonate-rich material. In a fossil context, such deposits can preserve evidence of organisms that lived in ancient marine environments. This geological setting gives the specimen added educational interest beyond its appearance as a mineralised fossil.
