Geology & Fossil Type:
This ammonite originates from the Middle Oxfordian, a stage within the Upper Jurassic, approximately 160 million years ago. The Oxfordian period was characterized by warm, shallow seas, which provided ideal conditions for ammonites to thrive. Fossils from Charente, France, are well-known for their excellent preservation and scientific significance, making them highly sought after by collectors and researchers alike.
Gregoryceras transversarium belongs to the subclass Ammonoidea, a group of extinct marine mollusks closely related to modern squids and octopuses. These creatures were efficient swimmers, using their chambered shells for buoyancy control, allowing them to navigate ancient oceans with ease. The fine ribbing and suture patterns on this ammonite provide valuable insight into the evolutionary adaptations of Jurassic cephalopods.
