Huge monster of the deep

  • The plesiosaur was unlike anything that lives today. It had a long neck and tail, a barrel-like body and four big fins.
  • It lived and thrived throughout the time of the dinosaurs, until about 65 million years ago.
  • It was one of the largest aquatic animals, growing up to 23 meters long – much longer than the Jurassic Coast bus!
  • The long neck of the plesiosaur is supported by approximately 40 individual vertebrae (bones). Humans – and even giraffes – only have seven!
  • Due to its size, it probably didn’t swim very fast. But it didn’t need speed as a defence – few other predators would dare attack it!
  • Some people think that the Loch Ness monster is a plesiosaur!
  • Some whole skeletons of plesiosaurs have been found, but more often it’s just  scattered bones left by scavenging animals.
  • You’ll find the remains of this plesiosaur at Bridport Museum.
