Geology & Fossil Type:
This ammonite originates from the Middle Oxfordian, a stage within the Upper Jurassic, dating back approximately 160 million years. During this time, much of Europe was covered by warm, shallow seas, which provided the ideal environment for ammonites to thrive. These fossils are essential for biostratigraphic dating, helping geologists correlate Jurassic rock formations across different regions.
Pseudogregoryceras belonged to the subclass Ammonoidea, an extinct group of marine mollusks closely related to modern squids and octopuses. Their chambered shells allowed for buoyancy control, enabling them to move efficiently through ancient marine ecosystems. The strong ribbing on their shells provided protection from predators and structural integrity for life in dynamic oceanic conditions.
