Mined from: Morocco

Era: Mesozoic
Geological Age: ~66–200 mya

Description: These Moroccan ammonites are fossilized remains of extinct marine cephalopods that lived in ancient oceans during the Mesozoic era. Each piece shows the classic spiral shell structure, often with visible chamber divisions (septa) and natural suture patterns that formed as the animal grew. The contrast between lighter calcified sections and darker matrix gives these specimens a clear, recognizable look, and many have been naturally or lightly polished to highlight internal detail.

Ammonites are commonly found in sedimentary rock deposits across Morocco, where they were preserved after being buried in ancient seabeds. Over millions of years, their shells mineralized, turning into stone while retaining their original structure. These fossils are widely studied as index fossils, helping geologists date rock layers and understand prehistoric marine environments.
