Moroccan Spiny Ammonite Fossil — Prepared Display Specimen

A striking prepared ammonite fossil from Morocco, displaying bold ribbing, raised tubercles and intricate mineral-filled suture patterns across its naturally sculptural form.

Ammonites were extinct marine cephalopods related to modern squid and octopus. Their chambered shells helped control buoyancy as they moved through ancient seas. The complex, branching lines visible on this specimen mark where internal chamber walls met the outer shell.

Specimen details

• Origin: Morocco
• Identification: Spiny ammonite, likely a Douvilleiceras-type form
• Probable age: Cretaceous Period
• Approximate size: 7 cm across, based on the photographed scale
• Preparation: Partly polished and prepared to reveal the shell structure and suture patterns
• Quantity: One specimen only—the exact piece photographed

Identification note: The ammonite identification is supported by the coiled shell, strong ornamentation and visible sutures. The precise genus, species, geological formation and age cannot be confirmed without the original locality record or laboratory examination, so the more specific attribution is offered as a likely comparison rather than a guarantee.

Natural fractures, weathering, mineral variation and preparation marks are part of this fossil’s history and individual character. Please review all photographs, as they form part of the description.
