Coeloceras pettos Fossil Ammonite, Lower Pliensbachian, Jurassic: Germany – 100% Genuine with Certificate of Authenticity

£12.60

This Coeloceras pettos fossil ammonite is an exceptional specimen from the Lower Pliensbachian Stage of the Jurassic Period, discovered in Germany. Coeloceras pettos is a fascinating ammonite species, known for its distinctive, ribbed shell and evolute coiling. This ammonite offers a unique glimpse into the marine ecosystems of the Lower Pliensbachian period, making it a perfect addition to any fossil collection.

Geological Information:

  • Geological Stage: Lower Pliensbachian, Jurassic (Approximately 190 to 183 million years ago)
  • Depositional Environment: During the Lower Pliensbachian, shallow marine seas covered much of what is now Germany. These seas were rich in marine life, providing an ideal environment for ammonites like Coeloceras pettos. The fossil was preserved in sedimentary deposits, including limestone and marl, formed by the accumulation of marine organisms and their remains. The Jurassic seas were warm and nutrient-rich, supporting diverse marine life such as ammonites, bivalves, and plankton.
  • Biozone: This fossil comes from the Lower Pliensbachian biozone, a period that saw significant marine biodiversity. Fossils from this biozone provide valuable information on the evolution and diversification of ammonites and other marine life during the early Jurassic.

Fossil Features:

  • Family: Ammonitidae
  • Super Family: Ammonoidea
  • Order: Ammonitida
  • Morphology: The Coeloceras pettos ammonite features a distinctive, ribbed, evolute shell. The ammonite has tight coiling, with expanding whorls as it matured. The ribs are evenly spaced and clearly defined, creating texture and structure along the shell. The ammonite also exhibits well-preserved suture lines, providing insight into its evolutionary development. The smooth texture of the shell and the overall shape reflect its adaptation to life in the marine environment of the Lower Pliensbachian period.

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.
  • Scale Rule: The scale rule squares/cube shown in the photo represents 1cm, allowing you to accurately gauge the size of the fossil. Full sizing details are available in the photograph.

Condition:

This Coeloceras pettos Fossil Ammonite is in excellent condition, showcasing its distinctive ribbing, evolute shell, and well-preserved suture lines. The fossil has been cleaned and treated for display, making it an ideal addition to any Jurassic ammonite collection or for those interested in the marine life of the Lower Pliensbachian period.

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
