Perisphinctes ammonite fossil – lower jurassic specimen from tulear, madagascar – genuine with certificate

Ammonites lived throughout the seas and swam by squirting water in one direction, to push themselves along. Ammonites appeared 425 million years ago and were very common ocean animals throughout the age of the dinosaurs. They died out 66 million years ago.

 

Perisphinctes is an extinct genus of ammonite 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 like 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.

 

These creatures varied in size, ranging from only a few millimeters to some fossils being found measuring a whopping 8 feet 96 inches.

Description

This listing features a beautifully preserved Perisphinctes ammonite fossil, discovered in Tulear, Madagascar and dating back to the Lower Jurassic period, approximately 163 million years ago. This is an excellent and highly collectable specimen, offering both aesthetic appeal and a rich scientific background.

Ammonites are among the most recognisable and iconic fossils due to their distinct spiral-shaped shells. These extinct marine molluscs thrived in oceans for millions of years, first appearing around 425 million years ago and becoming extinct approximately 66 million years ago, during the same mass extinction event that wiped out the dinosaurs.

The genus Perisphinctes is known for its intricately ribbed shell and was a free-swimming predator or scavenger that used jet propulsion, expelling water to move through the oceans. Although their shells are similar to modern nautilus, ammonites are more closely related to modern squid, cuttlefish, and octopuses.

Ammonites varied in size dramatically — from tiny shells just a few millimetres wide to giants stretching over 2 metres (6.5 feet). Their global distribution and rapid evolution make them ideal index fossils, often used by geologists to date rock layers.

This specimen has been carefully prepared to highlight the fine details of the shell, making it a perfect piece for collectors, educators, and fossil enthusiasts. Ammonites like this are not only beautiful but also help tell the story of our planet’s prehistoric seas.

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.
