Geological & Scientific Information:
- Species: Paraspidoceras mammillanum (with associated bivalve)
- Type: Fossil Ammonite with Bivalve (extinct marine invertebrates)
- Age: Approx. 160–157 million years old
- Geological Period: Jurassic
- Stage: Middle Oxfordian
- Location Found: Le Vanneau, Deux-Sèvres, France
- Order: Ammonitida
- Superfamily: Perisphinctoidea
- Family: Aspidoceratidae
- Morphological Features: Paraspidoceras is distinguished by its thick, involute shell with strong tuberculate ornamentation, rounded whorls, and pronounced ribbing. This specimen displays excellent preservation of both ammonite and bivalve features, offering a rare look at coexisting faunal elements.
- Depositional Environment: Shallow marine shelf with calm to moderately energetic conditions; sediments consist primarily of calcareous marl and limestone, promoting exceptional fossilisation.
- Scientific Importance: Ammonites of the genus Paraspidoceras are biostratigraphically significant within the Oxfordian stage. The presence of an associated bivalve adds paleoecological context, illustrating faunal associations and environmental conditions.
Additional Notes:
Specimens like this, showing multiple taxa preserved in association, are rare and highly prized by collectors and institutions. It offers insights into Jurassic paleoecology and is equally valuable for display or study.
