Includes Certificate of Authenticity

This RARE 8" Perisphinctes fossil ammonite is an extraordinary specimen from the Middle Jurassic Callovian deposits of Tulear, Madagascar, a globally renowned site for premium-quality ammonite fossils. Its size, preservation, and ribbed spiral morphology make it a stand-out piece for any fossil enthusiast or natural history collector.

Perisphinctes is a genus of extinct ammonite mollusks that flourished in the Jurassic seas around 166 to 163 million years ago. These cephalopods were free-swimming marine predators, with a shell structure that evolved for buoyancy and streamlined motion through the water. Their symmetrical ribbing and tight coiling make them especially attractive for both display and academic study.

What sets this particular specimen apart is its exceptional size and detail preservation. At 8 inches, it sits among the larger representatives of the genus—specimens of this calibre are significantly less common, making it an ideal centrepiece in any fossil display.

Fossils from the Tulear region are highly sought after for their superb quality and distinct coloration, a result of the mineral-rich Jurassic seabeds. This ammonite has been carefully cleaned and prepped, revealing the intricate suture lines and growth ribs typical of Perisphinctes ammonites.
