Protoceratops,
            
          
        
        
          which had
        
        
          a head frill but lacked a
        
        
          horn.
        
        
          
            
              Styracosaurus,
            
          
        
        
          or “spiked
        
        
          lizard”, had a fancy,
        
        
          horned frill.
        
        
          
            
              Pentaceratops
            
          
        
        
          had an
        
        
          enormous neck frill and
        
        
          three long horns.
        
        
          
            Other ceratopsians
          
        
        
          There were a number of
        
        
          different dinosaurs with
        
        
          horns and frills.

            One big dinosaur graveyard
          
        
        
          The Gobi Desert is littered with the
        
        
          remains of
        
        
          
            Protoceratops,
          
        
        
          and they
        
        
          show all stages of growth.

            Protoceratops
          
        
        
          roamed
        
        
          the Gobi Desert in Asia rather as
        
        
          sheep roam today. In fact, they
        
        
          were about the size of sheep.
        
        
          
            That’s not a fighter
          
        
        
          Protoceratops
        
        
          lacked
        
        
          any protection. Its
        
        
          small size would
        
        
          have made it the
        
        
          ideal prey for
        
        
          a number of
        
        
          meat-eaters.
        
        
          Like all the horn-face
        
        
          dinosaurs,
        
        
          Protoceratops
        
        
          had a parrot-like beak.
