The mighty
        
        
          
            T. rex
          
        
        
          roamed
        
        
          North America in the last
        
        
          couple of million years that
        
        
          dinosaurs ruled the planet.
        
        
          
            T. rex
          
        
        
          
            Was it a killer?
          
        
        
          We don’t really know if
        
        
          
            T. rex
          
        
        
          was a hunter
        
        
          or a scavenger. It may have attacked and
        
        
          killed, or it may have picked at dead or dying
        
        
          dinosaurs. It may have done both.

            T. rex
          
        
        
          had
        
        
          awesome curved
        
        
          teeth, each as long
        
        
          as a human hand.
        
        
          Altogether it
        
        
          had 58 of these
        
        
          pointed weapons.
        
        
          
            T. rex
          
        
        
          is short for
        
        
          
            Tyrannosaurus rex.
