Geological Context
The Lower Callovian is an interval within the Jurassic Period, a time renowned for extensive marine environments and a rich fossil record. Ammonites were extinct marine cephalopods that lived in the oceans and are recognised for their coiled shells, chambered construction and importance in studying ancient marine rocks. Their fossils are especially valued by collectors because named ammonite forms can provide insight into Jurassic biodiversity, geological succession and the changing distribution of marine life through time.
Proplanulites koenegi is presented here as the specimen’s supplied identification. The combination of a named ammonite, Lower Callovian age designation and Wiltshire locality gives this fossil clear relevance for enthusiasts interested in Jurassic stratigraphy and historically important British fossil material. Ashton Keynes is a notable locality name for collectors of fossils from Wiltshire, adding regional interest to this specimen.
Collector Interest
With its stated 6.5" size, this is a substantial display fossil for an ammonite collection, cabinet, study, office or educational setting. The named species identification allows it to be catalogued alongside other Jurassic ammonites and compared with specimens from different geological intervals or localities. It may also appeal to collectors building a themed display around Lower Callovian fossils, British Jurassic material or specimens connected with established private collections.
The fossil is from the Alice Purnell Collection, providing an additional collection-history detail for cataloguing and display. It can be presented as a conversation piece for anyone interested in ammonite taxonomy, Jurassic palaeontology, geological collecting or the fossil heritage of the United Kingdom.
