Geological & Scientific Information: Fossil Type: Ammonite Species: Hammatoceras victorii Order: Ammonitida Superfamily: Hildoceratoidea Family: Hammatoceratidae Geological Stage: Lower Toarcian (approx. 182.7 – 174.1 million years ago) Biozone: Likely falls within the Bifrons or Variabilis Zones Period: Jurassic Locality: Pesavo, Italy Depositional Environment: Marine shelf to deeper basin environment, with periodic anoxic events aiding in exceptional fossil preservation Morphology & Notable Features: Strong, sharp ribbing that bifurcates from the umbilical margin Typically planispiral and involute shell, with a narrow umbilicus Ribs often continue over the venter, which may show faint keels or a slightly flattened profile Excellent contrast and structure for visual display and scientific analysis Preserved in fine-grained limestone or marl matrix, which helps highlight shell ornamentation Scientific Significance: Hammatoceras victorii is part of a key genus for understanding Toarcian ammonite evolution, especially within the Mediterranean and Tethyan provinces. Specimens like this one are used for detailed biostratigraphic correlations and help define several important ammonite zones in the Lower Jurassic. This species was described from European fossil records and is part of the diverse faunal radiation following the end-Sinemurian extinction events. Its distinct ribbing makes it a marker species in many regional stratigraphic frameworks.
