Sisteronia was a fast-swimming marine reptile that lived in the Cretaceous seas. It had sharp teeth for catching small fish and squid. Sisteronia was an ichthyosaur, not a dinosaur, and looked a bit like a modern dolphin.1 2

makambo ya kitoko

Makambo ya kosepelisa

Sisteronia had teeth that were rectangular in cross-section, which is unusual among ichthyosaurs.2

It lived during the Albian and early Cenomanian stages of the Cretaceous, about 112 to 100 million years ago.2

Sisteronia is known from fossils found in England, France, and Russia, showing it lived in the seas of western Europe.3

This ichthyosaur belonged to the group Platypterygiinae, which were the last surviving ichthyosaurs before they went extinct.2

The name Sisteronia comes from the town of Sisteron in France, near where some of its fossils were found.1

Sisteronia had a raised process on the floor of the foramen magnum (the hole in the skull for the spinal cord), a unique feature not seen in other ichthyosaurs.2

Ntango bamonaki yango: Sisteronia was named by Fischer and colleagues in 2014, based on fossils from the Cambridge Greensand Member in England and the Vocontian Basin in France.3 1
Naino bazali kowelana: Scientists are still debating exactly how diverse late Cretaceous ichthyosaurs were, and whether Sisteronia was part of a broader European hotspot of ichthyosaur diversity.1
