Perisphinctes is an extinct genus of Ammonite cephalopod that lived in the lower Jurassic 163 million years ago.

 

Ammonites are one of the most recognisable fossils around, this is due to their familiar spiral shape shell, reminiscent of what we know as a snail shell, though these creatures are not related to snails at all! They were marine animals, present between 240 – 65 million years ago, who had a coiled external shell similar to that of the modern nautilus, and although they resembled a modern day nautilus, these molluscs are more closely related to living coleoids i.e. octopuses, squid, and cuttlefish.

Description

Discover a genuine piece of Earth’s ancient history with this stunning Perisphinctes ammonite fossil from Madagascar, dating back to the Lower Jurassic period. Estimated at approximately 163 million years old, this incredible fossil offers a direct connection to the prehistoric oceans that once teemed with life.

Geological Context: This ammonite was formed during the Lower Jurassic, a time of rapid marine diversification. The specimen comes from the fossil-rich regions of Madagascar, a globally renowned source of exceptionally preserved marine fossils. These geological formations were once seabeds, perfectly suited to the fossilisation process that preserved these extinct creatures in such striking detail.

Fossil Type and Species: The specimen is a fossilised Perisphinctes ammonite, an extinct genus of marine cephalopods. Despite their resemblance to modern-day snails, ammonites are in fact more closely related to octopuses, squids, and cuttlefish. Their coiled, chambered shells not only allowed for buoyancy control but also make them one of the most iconic and recognisable fossils today.

This specific specimen showcases the intricate ribbing and natural symmetry typical of the genus, with excellent preservation that reveals the evolutionary artistry of nature.

Why This Fossil is Special:

  • Genuine Perisphinctes ammonite from Madagascar
  • Approximately 163 million years old
  • Exceptional spiral shell preservation
  • A beautiful example of natural history and evolutionary design
  • Highly collectible and suitable for display or educational use

Ideal For: Collectors, fossil enthusiasts, educators, natural history lovers, and anyone looking to own a unique and tangible piece of Earth’s distant past.

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
