Pleuroceras spinatum Fossil Ammonite Multi Block, Upper Toarcian, Jurassic: Germany – 100% Genuine with Certificate of Authenticity

Description

This Pleuroceras spinatum fossil ammonite multi-block is an exceptional specimen from the Upper Toarcian Stage of the Jurassic Period, discovered in Germany. The Pleuroceras spinatum species is recognized for its distinctive coiled shell and fine ribbing, making it an attractive and significant specimen for fossil collectors. This multi-block piece showcases multiple ammonites, providing a rare and fascinating insight into the marine ecosystems of the Upper Toarcian period.

Geological Information:

• Geological Stage: Upper Toarcian, Jurassic (Approximately 182 to 174 million years ago)
• Depositional Environment: During the Upper Toarcian, shallow marine seas covered much of Germany. These seas were rich in marine life, supporting species like Pleuroceras spinatum. The ammonites were preserved in sedimentary deposits such as limestone and marl, formed over millions of years as marine organisms accumulated on the sea floor. The Jurassic seas were teeming with life, including ammonites, bivalves, and plankton, which made up the abundant ecosystem of the time.
• Biozone: This fossil is from the Upper Toarcian biozone, a period marked by the diverse ammonite species and other marine life. Fossils from this biozone help to understand the development and diversification of ammonites during the early Jurassic.

Fossil Features:

• Family: Ammonitidae
• Super Family: Ammonoidea
• Order: Ammonitida
• Morphology: The Pleuroceras spinatum ammonite features an evolute, tightly coiled shell with fine, smooth ribs running along the surface. The shell of this species exhibits a distinctive whorled pattern that gradually expands as the ammonite matures. The ribs are clearly defined and evenly spaced, offering a textural quality to the fossil. The multi-block nature of this specimen provides a captivating view of multiple ammonites in their natural preservation.
• The ammonite’s suture lines are well-preserved, offering valuable insights into its evolutionary development. The smooth and fine texture of the shell makes it an excellent example of Jurassic ammonites.
