Description
Iridescent Caloceras johnstoni Ammonite Fossil
This genuine fossil specimen is identified as Caloceras johnstoni, an ammonite associated with the Blue Lias and Jurassic geology of Watchet, Somerset, UK. Its iridescent appearance gives the specimen attractive visual character, making it an appealing addition to a fossil collection, natural history display, geological study collection or ammonite-themed interior display.
Identification and Geological Interest
Caloceras johnstoni is an ammonite fossil. Ammonites were extinct marine cephalopods with coiled shells, related in a broad zoological sense to modern squid, cuttlefish and nautiluses. Their fossilised shells are valued by collectors for their scientific importance, distinctive form and connection with ancient marine environments.
The specimen is associated with the Blue Lias, a well-known Jurassic geological unit. The Blue Lias is recognised for its fossil-bearing sedimentary rocks and has long been important to palaeontology and geology. Jurassic ammonites such as Caloceras provide an enduring link to marine life from this period and are particularly interesting to collectors who focus on stratigraphy, extinct cephalopods or the fossil heritage of the United Kingdom.
Locality
This specimen is from Watchet, Somerset, UK. The Watchet area is of interest to fossil collectors because of its Jurassic geology and association with the Blue Lias. A locality-linked fossil can add educational value to a collection by connecting the specimen with a specific geological region rather than presenting it only as an attractive natural object.
Display and Collecting
The iridescent visual effect makes this Caloceras johnstoni ammonite especially suitable for display in a cabinet, study, office, classroom or home collection. It can also be used as a conversation piece for anyone interested in ammonites, Jurassic fossils, British geology and palaeontology. Its named identification and geological association make it suitable for collectors who enjoy recording fossil localities and researching the rocks in which specimens are found.
