Lydna

Lydna is a genus of extinct marine reptiles belonging to the order Plesiosauria. These creatures lived during the Late Cretaceous period, approximately 100 to 66 million years ago. Fossils attributed to Lydna have been discovered in various locations, providing insights into the marine ecosystems of that era.

The anatomy of Lydna indicates it was a member of the pliosaur superfamily, characterized by a broad, flattened body and relatively short neck compared to its long skull. Its powerful jaws were likely lined with sharp teeth, adapted for catching fish and other small marine animals. The flippers of Lydna would have enabled it to navigate the oceans with considerable agility, though their exact swimming mechanism is a subject of ongoing research.

Lydna's taxonomic classification places it within the Plesiosauria, a diverse group of marine reptiles that dominated the Mesozoic seas. While closely related to other pliosaurs, Lydna possesses distinct anatomical features that differentiate it. The study of Lydna and its fossil remains contributes to our understanding of dinosaur-era marine biodiversity and the evolutionary history of marine reptiles. Further discoveries are crucial for a more complete picture of this ancient predator.
