RARE Schlotheimia redcarensis Fossil Ammonite Upper Hettangian Jurassic UK | Authentic Collector Specimen

Description

This listing features a rare and scientifically significant specimen of Schlotheimia redcarensis, a distinctive ammonite from the Upper Hettangian Stage of the Lower Jurassic, found at Tunstall Beach, Holderness, United Kingdom. Known for its paleontological value and distinctive morphology, this ammonite is a prized collector’s item and an excellent representative of post-Triassic ammonoid recovery.

Geological & Taxonomic Information:

• Fossil Type: Ammonite (extinct marine cephalopod)
• Species: Schlotheimia redcarensis
• Order: Ammonitida
• Superfamily: Psiloceratoidea
• Family: Schlotheimiidae
• Geological Stage: Upper Hettangian (Lower Jurassic)
• Age: Approximately 199.6 – 198.3 million years ago
• Location: Tunstall Beach, Holderness, East Yorkshire, UK
• Formation: Lower Lias Group
• Depositional Environment: Shallow marine shelf with predominantly mudstone and shale sedimentation, suggesting a calm, anoxic sea floor setting post-extinction recovery

Stratigraphic Significance: Schlotheimia species, including S. redcarensis, are key markers of the early Jurassic and help define biostratigraphic zones within the Hettangian. Their appearance reflects a rapid evolutionary radiation following the end-Triassic mass extinction.

Morphological Features:

• Strongly evolute shell with broad, open whorls
• Prominent, sharply ribbed ornamentation with radial ribs extending across the flanks
• Rounded ventral keel, typical of the genus
• Fine preservation of suture lines and umbilical detail

Notable Information: This species was named for its Redcar regional association, highlighting its British paleontological heritage. It is less commonly found compared to other Hettangian ammonites, increasing its rarity and desirability among fossil enthusiasts.
