Plesiosaurs, ancient marine sauropterygian reptiles, thrived from roughly 200 to 66 million years ago.
With long necks and paddle-like limbs, they hunted fish and squid.
They varied in size and inhabited diverse oceanic habitats.
Extinction coincided with the end of the Mesozoic Era due to various factors.
