About Plesiosauria:

The Plesiosaur is the first marine animal featured in this Coin Series. The Plesiosaur lived during the Triassic (180-225 million years ago) and Jurassic period (135-180 million years ago).

Plesiosauria ("Plesios" meaning "near to" and "sauros" meaning "lizard") are an order of extinct Mesozoic marine reptiles belonging to the Suaropterygia.

Plesiosaurs first appeared in the latest Triassic Period in the Rhaetian stage, about 203 million years ago and 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). They had a world-wide oceanic distribution.

Plesiosaurs were among the first fossil reptiles to be discovered in the beginning of the 19th Century.

In 1921, they were described as Plesiosaurus. Since then more than a hundred valid species have been described.

As they had a distinct build, they were named asa separate order in 1835.

Since the early 21st Century, the number of discoveries has increased leading to an improved understanding of their anatomy, relationships and way of life.

Plesiosaurs 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. Plesiosaurs breathed air and bore live young and were warm-blooded. 

With their streamlined body, strong flippers and rows of sharp teeth paired with one of the strongest jaws of the era, they were the perfect sea predators.

Plesiosaurs showed two main morphological types -

- Some species, with the "plesiosauromorph" build had 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 17.0 metres had the "pliosauromorph" build with a short neck and a large head - these were apex predators, fast hunters of large prey.

The Plesiosaur is featured on this large 65.0 mm, 3 Oz Silver Proof Coin.
