Identification and Geological Context

Proplanulites laevigatus is an ammonite identification from the Jurassic period.

Kellaways Rock is included in the specimen’s identification and geological information. The associated location is recorded as SEMINGTON by pass, United Kingdom. These details make the fossil particularly relevant to collectors interested in British Jurassic palaeontology and regional geological material.
