Arkéoissa

Arkéoissa is a genus of prehistoric marine reptiles belonging to the extinct order Plesiosauria. These creatures inhabited the oceans during the Mesozoic Era, specifically during the Late Cretaceous period. While fossils are rare, the available evidence suggests that Arkéoissa were medium-sized plesiosaurs, likely possessing the characteristic long neck and four paddle-like limbs common to this group. Their diet is presumed to have consisted of fish and other small marine organisms, based on the feeding adaptations observed in related plesiosaur species.

The genus Arkéoissa was first described based on fossil remains discovered in sedimentary rock formations. The exact phylogenetic placement of Arkéoissa within the broader plesiosaur classification is still a subject of ongoing research. Paleontologists continue to study the limited fossil material to gain a better understanding of its anatomy, evolutionary relationships, and ecological role in ancient marine ecosystems. The discovery of Arkéoissa contributes to our knowledge of the diversity and evolution of marine life during the age of dinosaurs.
