Description
This listing features a very rare and highly sought-after fossil ammonite, Nipponites bacchus, a heteromorph ammonite from the Coniacian stage of the Late Cretaceous period. This extraordinary specimen originates from the Yezo Group, Hokkaido, Japan, a world-renowned fossil site.
About Nipponites bacchus:
Nipponites is one of the most distinctive heteromorph ammonites, characterized by its coiled and irregular shell structure. Unlike typical ammonites with symmetrical spirals, Nipponites features an intricate, tangled appearance, making it one of the most unique ammonites ever discovered. This peculiar shape likely influenced its buoyancy and movement in the ancient marine environment.
This particular species, Nipponites bacchus, is a rare variety found exclusively in Japan. It belongs to the family Nostoceratidae, known for their evolutionary deviation from typical ammonoid forms, creating almost alien-like, asymmetrical coiling.
Geological Context:
- Formation: Yezo Group
- Age: Coniacian, Late Cretaceous (~89–86 million years ago)
- Location: Hokkaido, Japan
The Yezo Group is a well-documented marine sedimentary sequence, providing insight into ancient Cretaceous seas where Nipponites once thrived. The region has yielded some of the most scientifically significant ammonite fossils in the world.
