Browsing: Plesiosaurs

Plesiosaurs were marine reptiles that lived during the Mesozoic Era, thriving from the Late Triassic to the end of the Cretaceous period. Known for their distinctive body plan, they had broad, flat bodies, strong flippers for efficient swimming, and typically long necks with small heads, though some species had shorter necks and larger heads adapted for powerful bites. Despite often being mistaken for dinosaurs, plesiosaurs were a separate group of marine reptiles that evolved independently. They were apex predators in their ecosystems, feeding on fish, squid, and other marine creatures. Their fossilized remains have been found on every continent, offering key insights into ancient ocean ecosystems and reptilian evolution.
