Step back in time with this large raw ammonite fossil from Agadir, Morocco, dating to the Cretaceous period around 110–120 million years ago. Ammonites were extinct marine molluscs related to modern squid and octopus, and their iconic ribbed shells are preserved in sandy-coloured limestone.

These larger ammonites, measuring 24–30cm, make impressive centrepieces for fossil collections, museum-style displays, or educational study. Their spiral form reflects the natural Fibonacci sequence, a striking reminder of the beauty of mathematics in nature.

Ammonite fossils have fascinated humans for centuries. Their name comes from the Egyptian god Ammon, whose ram’s horns resembled the ammonite spiral. First scientifically described in the 19th century, Moroccan ammonites became especially sought after in the 20th century, when the Agadir region gained recognition as one of the world’s richest fossil localities.

Frequently Asked Questions (FAQ)

How old are these ammonites?
They are approximately 110–120 million years old, from the Cretaceous period.

Why are larger ammonites valuable?
Larger specimens (24–30cm) are less common, making them prized for display and collection.

Where do these fossils come from?
These ammonites were sourced from Agadir, Morocco — one of the most important fossil regions globally.

Why are ammonites important in science?
They are index fossils, used by geologists to date rock layers and reconstruct ancient marine ecosystems.
