Collection: Ammonite Fossils

Ammonites are the coiled shells of ancient marine mollusks, prized by collectors for their striking spiral patterns and the way they capture a moment of deep geologic time in polished stone. Their natural symmetry and the range of colors revealed through cutting and polishing make each piece a distinctive addition to a fossil or natural history collection.

This collection includes polished ammonite fossil halves and slices from Morocco showing spiral patterns, a matrix sculpture piece, a dark ammonite fossil with golden shimmer, and an authentic Cretaceous ammonite fossil, alongside Madagascar ammonites from the Early Cretaceous and Late Jurassic, some mounted with display stands. Buyers should look closely at the polish quality, the visibility and definition of the spiral chambers, and whether a piece includes a stand for display.
