Geological Age and Provenance

This ammonite dates back to the Upper Toarcian stage of the Lower Jurassic, approximately 178 – 175 million years ago. During this interval, much of Europe was covered by shallow epicontinental seas that supported abundant marine life. The region of Beyruth, Germany, is particularly well known for its fossil deposits, where ammonites, belemnites, and other marine organisms were preserved in fine-grained sediments that captured exquisite detail.

The Toarcian is a critical stage in the geological timescale because it coincides with important global events, including significant changes in ocean chemistry and marine biodiversity. Ammonites such as Pleurolytoceras hircinum provide essential data for understanding these events and for correlating rock layers across Europe.

Scientific Classification and Identification

This fossil is identified as Pleurolytoceras hircinum, belonging to the family Lytoceratidae, within the superfamily Lytoceratoidea and order Ammonitida. The Lytoceratidae are a distinctive group of ammonites characterised by evolute shells and highly complex suture patterns, making them particularly striking and scientifically important.

Pleurolytoceras hircinum is an especially notable species within the genus, valued for its elegant coiling and unique features. Its presence in the Upper Toarcian deposits of Germany makes it an important reference fossil for this geological stage.

Morphology and Distinctive Features

The shell morphology of Pleurolytoceras hircinum is characterised by its evolute whorls, where all the whorls are exposed, and its intricate suture lines, which form a complex and decorative pattern across the surface of the shell. These sutures consist of deep lobes and saddles that are highly diagnostic of the Lytoceratidae family.

The smooth outer whorls and refined symmetry of the shell contribute to its aesthetic appeal. This design is not merely ornamental but also reflects evolutionary adaptations for buoyancy control and stability, enabling the animal to thrive in open marine environments as a strong swimmer and active predator.

Depositional Environment

The Beyruth region of Germany is a classic fossil locality, with sedimentary deposits laid down in shallow marine settings during the Jurassic. Fine silts and muds gently accumulated on the sea floor, entombing ammonites and other organisms under low-oxygen conditions that favoured long-term preservation. As a result, ammonites from this region often retain fine details of their morphology, providing both visual beauty and scientific value.

Collectible and Scientific Significance

Specimens of Pleurolytoceras hircinum are considered rare, and their value lies not only in their scarcity but also in their contribution to scientific understanding of Jurassic ammonite faunas. As an important genus in the Toarcian biostratigraphy of Europe, Pleurolytoceras is widely studied by paleontologists. For collectors, it offers the chance to own a specimen that represents both scientific history and natural artistry.
