100% Genuine Rare Apoderoceras ferox Ammonite Fossil

This listing is for a rare Apoderoceras ferox ammonite fossil from the Upper Pliensbachian stage of the Jurassic period, collected at St Peters Field, Radstock, Somerset, United Kingdom. The specimen pictured is the exact fossil you will receive, shown alongside a 1cm scale cube for accurate sizing. All of our fossils are 100% genuine and come with a Certificate of Authenticity, ensuring provenance and authenticity.

Geological Background – Upper Pliensbachian, Jurassic

The ammonite originates from the Upper Pliensbachian stage of the Early Jurassic, approximately 185 million years ago. During this time, much of Britain lay beneath shallow epicontinental seas, part of a marine environment that fostered exceptional biodiversity and preserved countless marine fossils.

The deposits at St Peters Field, Radstock are part of the Lower Lias Group, renowned for producing ammonites of extraordinary quality and significance. Fossils from this site are particularly tied to the Spinatum Zone, a stratigraphic marker of global importance that allows geologists to correlate Early Jurassic deposits across Europe.

Fossil Type and Species – Apoderoceras ferox

Apoderoceras ferox is an extinct ammonite belonging to the order Ammonitida, superfamily Eoderoceratoidea, and family Eoderoceratidae. The genus Apoderoceras is distinctive for its robust, ornamented shells, and the species ferox is one of the more sought-after ammonites from the Pliensbachian due to its rarity and striking features.

As nektonic predators, ammonites like Apoderoceras were active hunters, swimming through Jurassic seas using jet propulsion and feeding on smaller marine organisms. Their coiled, chambered shells provided buoyancy regulation, enabling them to navigate efficiently within their environment.

Morphology and Distinguishing Features

The shell of Apoderoceras ferox is evolute, with earlier whorls visible due to open coiling. Its most distinguishing feature is its bold ribbing, which runs strongly across the flanks and often culminates in prominent tubercles or spines at the ventrolateral margin. These ornamentations give the ammonite a striking, rugged appearance and reflect the species name “ferox,” meaning “fierce.”

The venter (outer whorl edge) is typically rounded, with ribs that may cross it in a continuous pattern. Sutures are complex and deeply lobed, a hallmark of ammonitids. The combination of coarse ribbing, tuberculation, and open whorl structure makes Apoderoceras ferox one of the most recognisable ammonites from the Spinatum Zone.

Biozone and Scientific Importance

Apoderoceras ferox is a key ammonite associated with the Spinatum Zone of the Upper Pliensbachian, making it an important index fossil. Its restricted stratigraphic distribution and recognisable morphology allow geologists to accurately date and correlate Early Jurassic deposits.

The presence of this species at St Peters Field provides valuable information about the ammonite faunas of the British Jurassic and contributes to broader studies of ammonite evolution and paleoenvironments during this interval.

Collectors and Enthusiasts

For collectors, a rare Apoderoceras ferox ammonite fossil is an exceptional find. Its coarse ribbing, spines, and rarity make it a standout piece in any ammonite collection. Combined with its provenance from Radstock, this specimen is both scientifically significant and visually impressive, appealing to paleontologists, educators, and fossil enthusiasts alike.

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.
