The Plesiosaurus or Plesiosauria are an order or clade of extinct Mesozoic marine reptiles (marine Sauropsida), belonging to the Sauropterygia.

Plesiosaurus or Plesiosaurus dolichoderius first appeared in the latest Triassic Period, possibly in the Rhaetian stage, about 203 million years ago. They became especially common during the Jurassic Period, thriving until their disappearance due to the Cretaceous–Paleogene extinction event at the end of the Cretaceous Period, about 66 million years ago. Plesiosaurus or Plesiosaurus dolichoderius had a worldwide oceanic distribution.

Plesiosaurus or Plesiosaurus dolichoderius were among the first fossil reptiles discovered. In the beginning of the nineteenth century, scientists realized how distinctive their build was and they were named as a separate order in 1835.

The first plesiosaurian genus, the eponymous Plesiosaurus, was named in 1821. Since then, more than a hundred valid species of  or Plesiosauria have been described. In the early twenty-first century, the number of discoveries has increased, leading to an improved understanding of their anatomy, relationships and way of life.

Plesiosaurus or Plesiosaurus dolichoderius had a broad flat body and a short tail. Their limbs had evolved into four long flippers, which were powered by strong muscles attached to wide bony plates formed by the shoulder girdle and the pelvis.

The flippers made a flying movement through the water. Plesiosaurus or Plesiosaurus dolichoderius breathed air, and bore live young; there are indications that they were warm-blooded.

Plesiosaurus or Plesiosaurus dolichoderius showed two main morphological types. Some species, with the “plesiosauromorph” build, had (sometimes extremely) long necks and small heads; these were relatively slow and caught small sea animals.

Other species, some of them reaching a length of up to seventeen metes, had the “pliosauromorph” build with a short neck and a large head; Plesiosauria were apex predators, fast hunters of large prey.
