Anything it could catch, including pterosaurs who flew too close to the water’s surface.
        
        
          Some people
        
        
          think the “monster” in
        
        
          Lock Ness, a Scottish Lake,
        
        
          is a plesiosaur that was trapped
        
        
          there when the sea receded
        
        
          millions of years ago!

          The dagger-like teeth

            Elasmosaurus
          
        
        
          was also
        
        
          a plesiosaur, but it was
        
        
          long-necked. Its four
        
        
          paddle-shaped limbs
        
        
          propelled it easily
        
        
          through the water.
        
        
          It grew up to 14 m
        
        
          (46 ft) in length.

          survive since the dinosaurs.

          ancestors date back to the

          too are great survivors.
        
        
          
            I recognize that!
          
        
        
          Many Mesozoic occupants of
        
        
          the Earth’s seas would have
        
        
          been familiar to us.
