Geological Information:
Geological Stage: Callovian, Jurassic (Approximately 166 to 161 million years ago)
Depositional Environment: The Callovian period was characterized by warm, shallow seas that covered much of Europe, including the area now known as Calvados, France. These seas were home to a rich variety of marine life, including ammonites like Grossouvria subtilis. The fossil was preserved in the sediments of these ancient seas, offering a detailed snapshot of Jurassic marine ecosystems.
Biozone: This fossil comes from the Callovian biozone, known for its diversity of ammonites, many of which evolved into distinct species and contributed significantly to marine ecosystems of the time.
Fossil Features:
Family: Desmoceratidae
Super Family: Desmoceratoidea
Order: Ammonitida
Morphology: The Grossouvria subtilis ammonite is characterized by its distinctly ribbed, evolute shell, which displays a pronounced, finely detailed surface texture. The whorl of this ammonite is well-defined, and the ribs are strongly visible, contributing to the characteristic look of the species. The shell is typically compressed with a rounded, smooth curvature, ideal for protection in the marine environment.

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.
