  Brontozoum \Bron`to*zo"um\, n. [NL., fr. Gr. ? thunder + ?
     animal.] (Paleon.)
     An extinct animal of large size, known from its three-toed
     footprints in Mesozoic sandstone.
     [1913 Webster]
  


     Note: The tracks made by these reptiles are found eighteen
           inches in length, and were formerly referred to
           gigantic birds; but the discovery of large bipedal
           three-toed dinosaurs has suggested that they were made
           by those reptiles.
