Ancient mega-predatory pliosaur: Unveiling a Dynasty

The remains of the oldest-known mega-predatory pliosaur reptile, a 170-million-year-old sea reptile from the age of dinosaurs, have been analyzed after being discovered 40 years ago in France. Pliosaurs were a unique group of aquatic reptiles that coexisted with dinosaurs and are distinguished by their long necks, barrel-shaped bodies, and four flippers on each foot. The fossils were donated to the Natural History Museum in Luxembourg by the Association minéralogique et paléontologique d’Hayange et des environs.
