Iridescent Cadoceras johnsoni Fossil Ammonite Hettangian Jurassic Watchet UK

Description

Fossil Identification

This listing presents an iridescent Cadoceras johnsoni fossil ammonite associated with the Hettangian stage of the Jurassic. The specimen information identifies its location as Watchet, Somerset, United Kingdom, giving it a clearly documented British geological context for fossil collectors, ammonite enthusiasts and natural history displays.

Cadoceras johnsoni is the identified ammonite represented by this specimen. Ammonites were extinct marine cephalopods related to modern squid, cuttlefish and nautiluses. Their coiled shells are among the most recognisable fossils in palaeontology and are widely collected for their scientific interest, historical importance and decorative appeal. The iridescent quality noted for this fossil adds visual interest and makes it particularly suitable for a display cabinet, geological study collection or ammonite-themed décor.

Geological Context

The specimen is identified as Hettangian and Jurassic in age. The Hettangian is the earliest stage of the Jurassic Period, placing this fossil within an important interval of Earth history following the end of the Triassic. Jurassic fossils are valued by collectors because they document ancient marine life and provide an accessible connection to the changing environments and biodiversity of the Mesozoic Era.

Watchet, Somerset, is a recognised fossil locality in the United Kingdom and gives this specimen a specific regional connection rather than only a broad country-level origin. Its stated locality and geological designation make it an interesting addition to collections focused on British fossils, Jurassic material, ammonites or geographically documented specimens.

Collector and Display Appeal

This Cadoceras johnsoni ammonite fossil offers several points of interest in one specimen: an identified fossil name, an iridescent appearance, a Hettangian Jurassic designation and a Watchet, Somerset locality. It can be used as an educational aid when discussing ammonites, Jurassic geology and fossil collecting, or displayed alongside other British geological specimens. The specimen is also suitable for collectors who appreciate fossils with both scientific naming and attractive natural visual character.

Its compact subject matter makes it relevant to palaeontology collections, geology study displays, classroom-inspired exhibits and natural history interiors. The combination of the Cadoceras johnsoni identification and British locality provides useful descriptive information for cataloguing and future reference.
