RARE Fossil Ammonite Arcestes Triassic Carnian Austria Fenerkrugel Authentic Specimen Jurassic Marine Invertebrate
£ 36.00
RARE Fossil Ammonite – Arcestes species from the Triassic Period, Carnian Stage,
found at Fenerkrugel, Austria.This exceptional ammonite fossil represents the genus Arcestes, a well-known group of extinct ammonoids from the Middle to Late Triassic period. This particular specimen originates from the Carnian Stage, roughly 237 to 227 million years ago, a critical interval marking the onset of modern reef ecosystems and the evolutionary radiation of ammonoids after the Permian extinction.Geological & Paleontological Context:
• Location: Fenerkrugel, Austria
• Formation/Zone: Carnian Stage, Triassic System
• Fossil Type: Ammonite (cephalopod mollusc)
• Genus: Arcestes
• Geological Age: Late Triassic (Carnian Stage, ~230 Ma)
• Order: Ceratitida
• Superfamily: Arcestaceae
• Family: ArcestidaeMorphology & Features: Arcestes ammonites are known for their unusual shell morphology—characteristically almost spherical or globular shells with low ornamentation, a broad umbilicus, and simple to slightly ceratitic suture lines. These forms are thought to have been nektonic or possibly planktonic, with a unique mode of life compared to other ammonoids.This particular specimen displays the classic globose profile with well-defined chambering and preserved suture detail, making it both scientifically valuable and aesthetically unique for collectors.Depositional Environment: These fossils were originally preserved in shallow marine carbonate settings of the Tethyan realm, which during the Triassic period covered much of central Europe, including modern-day Austria. The environment was likely a warm, reef-fringed epicontinental sea.Why This Specimen?
• Carefully selected and professionally sourced from Fenerkrugel, Austria.
• Comes with a Certificate of Authenticity.
• The specimen shown in the photo is the exact one you will receive.
• Scale shown (1 cm cubes) for precise size reference – please see photo for full measurements.Ideal for: Collectors of Triassic fossils, palaeontology enthusiasts, museum-quality displays, and educational institutions. A rare opportunity to own a piece of deep-time marine life from a pivotal moment in Earth’s history.All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity.
