Genuine Cardioceras buckowskii Fossil Ammonite

This listing features a rare and authentic Cardioceras buckowskii fossil ammonite from the Oxfordian Stage of the Jurassic Period, discovered at Redcliff Point, Dorset, United Kingdom. Dating back to approximately 163–157 million years ago, this ammonite represents a remarkable relic from the Upper Jurassic seas that once covered southern England. The specimen offered here is the exact fossil shown in the photographs, chosen with care for its scientific significance and collector’s value. Each piece is supplied with a Certificate of Authenticity, ensuring it is 100% genuine.

Geological Background

The Oxfordian Stage of the Jurassic Period was a time of extensive marine transgressions across Europe. In Dorset, the coastline exposes world-famous Jurassic strata that form part of the Jurassic Coast UNESCO World Heritage Site, celebrated for its exceptional fossil record. Redcliff Point is particularly well known for its Oxfordian deposits, which preserve a wealth of marine organisms, including ammonites, bivalves, gastropods, and marine reptiles.

The sediments deposited in this area were largely marine clays and marls, laid down in warm shallow seas. These fine-grained deposits created ideal conditions for fossil preservation, protecting delicate ammonite shells from erosion and compaction. Fossils such as Cardioceras buckowskii allow palaeontologists to study the biodiversity, evolutionary trends, and palaeoenvironments of the Late Jurassic seas.

Scientific Classification

  • Genus: Cardioceras
  • Species: Cardioceras buckowskii
  • Family: Cardioceratidae
  • Superfamily: Stephanoceratoidea
  • Order: Ammonitida
  • Class: Cephalopoda
  • Age: Oxfordian, Upper Jurassic (~163–157 million years ago)
  • Locality: Redcliff Point, Dorset, United Kingdom

Morphological Features

Cardioceras buckowskii is characterised by its strong ribbing, complex suture patterns, and robust shell form. Ribs often bifurcate as they extend from the inner whorls to the outer margins, giving the shell a distinctive ornamented appearance. The ribs not only strengthened the shell but also may have influenced the animal’s buoyancy and movement within the water column.

The suture lines of this species are particularly intricate, showing deeply lobed and serrated patterns that mark the junction between septa and shell walls. These features are highly valued both for their scientific information and their aesthetic beauty, making Cardioceras buckowskii a desirable fossil for collectors.

Stratigraphic and Palaeontological Importance

As part of the genus Cardioceras, this ammonite is an important index fossil for the Oxfordian Stage. Its relatively short stratigraphic range and wide geographic distribution make it an essential tool for correlating Jurassic marine strata across Europe. The presence of Cardioceras buckowskii in the Redcliff Point sequence contributes to the detailed stratigraphic framework of the Dorset coast, an area long studied by palaeontologists since the early 19th century.

Ammonites of this genus are frequently associated with specific biozones, allowing geologists to refine the timescales of Jurassic stratigraphy. Their abundance and diversity in the Oxfordian seas underline their ecological dominance during this period.

Depositional Environment

During the Oxfordian, Redcliff Point and the surrounding Dorset area were submerged beneath a shallow epicontinental sea. The warm, nutrient-rich waters provided an ideal habitat for ammonites, which thrived alongside belemnites, fish, and large marine reptiles such as ichthyosaurs and pliosaurs. Low-energy environments allowed sediment to accumulate steadily, burying ammonite shells before they could be destroyed by scavengers or currents. As a result, specimens such as this one are preserved in excellent detail.

Collectability and Display Value

This Cardioceras buckowskii fossil ammonite from Redcliff Point, Dorset is a superb example of a scientifically significant and visually striking fossil. It serves as both a valuable collector’s piece and an educational specimen, highlighting the biodiversity of the Oxfordian seas. Whether displayed in a private collection, used in academic study, or presented as a unique natural history item, this ammonite stands out for its quality, provenance, and geological importance.

  • Type: Fossil Ammonite – Cardioceras buckowskii
  • Age: Oxfordian, Upper Jurassic (~163–157 million years ago)
  • Origin: Redcliff Point, Dorset, United Kingdom
  • Scale: Rule squares/cube = 1 cm (see photographs for exact sizing)
  • Authenticity: 100% genuine specimen with Certificate of Authenticity
  • Guarantee: The fossil shown is the actual specimen you will receive

An outstanding ammonite, this specimen offers a direct connection to the Jurassic seas of Dorset and represents a timeless piece of Britain’s rich fossil heritage.

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
