Cardioceras buckowskii Fossil Ammonite Lower Oxfordian Jurassic Scarborough Yorkshire UK Authentic

Authentic Cardioceras buckowskii Ammonite Fossil

This listing features a Cardioceras buckowskii ammonite fossil, a rare and scientifically significant specimen from the Lower Oxfordian stage of the Jurassic period (approximately 163–160 million years ago). Found near Scarborough, Yorkshire, United Kingdom, this ammonite is a superb representation of one of the most iconic Oxfordian ammonites. The fossil displays excellent preservation with diagnostic ribbing and coiling patterns, making it both a research-quality specimen and a striking addition to any fossil collection. Photographed alongside a 1 cm scale cube, the fossil is offered exactly as pictured. As always, this specimen is 100% genuine and is accompanied by a Certificate of Authenticity.

Geological Context

The Lower Oxfordian is the earliest subdivision of the Oxfordian stage, part of the Upper Jurassic. During this time, what is now Yorkshire was covered by shallow epicontinental seas. These marine environments provided ideal conditions for ammonites, which thrived in large numbers and diversified into many forms, including Cardioceras buckowskii.

The Scarborough region is globally renowned for its Jurassic exposures, with fossil-bearing deposits offering insights into marine ecosystems and stratigraphic sequences of the Oxfordian. Ammonites like Cardioceras are key to defining the Oxfordian biozones, making them invaluable in biostratigraphy for correlating layers across Europe.

Morphological Features

The Cardioceras buckowskii specimen shows distinctive traits that aid in its identification:

• Shell Form: Moderately involute coiling with compressed whorls.
• Ribbing: Strong, radial ribs running across the flanks and projecting onto the keel.
• Keel: A pronounced keel, typical of Cardioceras, offering hydrodynamic efficiency.
• Whorl Section: Subrounded to slightly compressed, maintaining symmetry.
• Sutures: Complex, serrated suture lines preserved in some areas, reflecting the intricate internal structure.

These features highlight the ammonite’s adaptations for life as a fast-moving nektonic predator, hunting smaller marine organisms in the Jurassic seas.

Scientific and Collector Importance

Cardioceras buckowskii belongs to the order Ammonitida, superfamily Perisphinctoidea, and family Cardioceratidae. Its importance lies in its use as a zonal fossil for the Lower Oxfordian, with its presence marking the Cardioceras cordatum Zone, one of the most important ammonite biozones of the Jurassic.

For collectors, this fossil is highly desirable because of its rarity, scientific significance, and the prestige of its Yorkshire provenance. Ammonites from Scarborough are increasingly scarce, making this specimen a valuable piece for both academic and private collections.
