• Species: Reineckeia (Reineckeia) anceps anceps
• Common Name: Fossil Ammonite
• Geological Period: Jurassic
• Stage: Middle Callovian (~165 million years ago)
• Biozone: Reineckeia anceps Zone (ammonite-based zonation)
• Location: Poitiers, France
• Size: Approx. 6 inches (15.2 cm) GEOLOGICAL & DEPOSITIONAL ENVIRONMENT:During the Middle Jurassic, the Poitiers region was submerged under a warm, shallow epicontinental sea. Sediments deposited in this marine environment were typically marly and clay-rich, with low energy conditions that promoted excellent fossil preservation. These strata are part of the global Callovian sequence, well-known for diverse ammonite faunas.The genus Reineckeia is a key marker fossil, particularly in defining biostratigraphic boundaries within the Callovian. TAXONOMY & CLASSIFICATION:
• Phylum: Mollusca
• Class: Cephalopoda
• Order: Ammonitida
• Superfamily: Stephanoceratoidea
• Family: Reineckeiidae
• Genus: Reineckeia
• Subgenus: Reineckeia (Reineckeia)

• Index fossil for the Reineckeia anceps ammonite zone
• Excellent condition and rare size
• Ideal for collectors, educators, and museums
