Amaltheus gibbosus Fossil Ammonite, Upper Pliensbachian, Jurassic: Ilminster, United Kingdom – 100% Genuine with Certificate of Authenticity
£12.60
This Amaltheus gibbosus fossil ammonite is an outstanding specimen from the Upper Pliensbachian Stage of the Jurassic Period, discovered in Ilminster, United Kingdom. Amaltheus gibbosus is a well-known ammonite species, prized for its distinctively ribbed shell and prominent nodular features. This ammonite offers a unique view into the marine ecosystems of the Upper Pliensbachian period, making it a perfect addition to any fossil collection.
Geological Information:
- Geological Stage: Upper Pliensbachian, Jurassic (Approximately 183 to 174 million years ago)
- Depositional Environment: During the Upper Pliensbachian, shallow marine seas covered much of what is now the United Kingdom, including the Ilminster region. These seas were rich in nutrients and provided the ideal habitat for ammonites like Amaltheus gibbosus. The fossil was preserved in sedimentary deposits such as limestone and marl, which formed from the accumulation of marine organisms and their remains. The seas during this period supported a variety of marine life, including ammonites, bivalves, and plankton.
- Biozone: This fossil comes from the Upper Pliensbachian biozone, a period characterized by the diversification of ammonites and other marine life. Fossils from this biozone provide valuable insight into the marine biodiversity of the early Jurassic period and the evolutionary development of ammonites.
Fossil Features:
- Family: Ammonitidae
- Super Family: Ammonoidea
- Order: Ammonitida
- Morphology: The Amaltheus gibbosus ammonite features a distinctively ribbed, evolute shell with nodule-like features that create a unique textured surface. The ammonite’s whorls are tightly coiled, gradually expanding outward as it matured. The ribs are clearly defined, and the nodular features on the shell make this species easy to identify. The suture lines of the ammonite are visible and well-preserved, offering further insight into its evolutionary structure. The shell’s evolute shape gives it a striking appearance.
Notable Details:
- This fossil is 100% GENUINE and comes with a Certificate of Authenticity, ensuring its authenticity and historical value.
- The specimen has been carefully selected for its high-quality preservation. The photograph provided shows the actual specimen you will receive, ensuring full transparency in your purchase.
