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

Description

This Pleuroceras spinatum fossil ammonite is a stunning specimen from the Upper Toarcian Stage of the Jurassic Period, discovered in Belgium. Pleuroceras spinatum is an ammonite species recognized for its distinctively ribbed, coiled shell and smooth texture, making it a desirable addition to any fossil collection. The fossil captures a snapshot of Jurassic marine life from the Toarcian period, allowing collectors and fossil enthusiasts to own a piece of ancient marine history.

Geological Information:

• Geological Stage: Upper Toarcian, Jurassic (Approximately 183 to 174 million years ago)
• Depositional Environment: The Upper Toarcian period was characterized by shallow seas that covered much of what is now Belgium. These seas were teeming with marine life, including ammonites like Pleuroceras spinatum. The ammonite fossil was preserved in sedimentary rock, primarily limestone, formed by the accumulation of marine organisms and their remains. The seas during this time were rich in nutrients, providing an ideal environment for the thriving marine ecosystems that included ammonites, bivalves, and plankton.
• Biozone: This fossil comes from the Upper Toarcian biozone, which represents a period of significant marine diversification. The biozone is marked by the abundance of ammonites and their crucial role in the marine food chain. Fossils from the Upper Toarcian biozone offer valuable insights into the evolution of marine life and the environmental conditions of the time.

Fossil Features:

• Family: Ammonitidae
• Super Family: Ammonoidea
• Order: Ammonitida
• Morphology: The Pleuroceras spinatum ammonite features a distinctively coiled shell with clearly defined ribs running along the surface. The ammonite’s whorls are evolute, meaning they expand outward as the ammonite matured, revealing its growth stages. The ribs on the shell are evenly spaced and clearly visible, adding texture to the fossil. The suture lines are well-defined, helping to identify the species and illustrating the ammonite’s evolutionary features. The evolute coiling is a key characteristic of the species, contributing to its unique appearance.
