HABITS \M> MANNER OF LIFE 23 



On the defensive side, there is the crest itself, especially the squamosal area which would receive 

 the brunt of the attack, and the thickened and highly rugOSC upper and anterior rim ol the orbit, which 

 was for the protection of the eye. I cannot think of the eye as protruding, as 1 latcher believed, and 

 hence the vision must have been limited to a lateral held with a blind area immediately in front, as 

 with the sperm whale. 



One has to consider not only combats with rival males but protection against such carnivorous 

 enemies as Gorgosaurus of Belly River time and, above all, the huge Tyratmosaurus of the Lance. 

 That the menace of these beasts of prey was real is attested by the facts that little or no sexual dis- 

 tinction is provable among ceratopsians and that apparently both males and females of a species 

 possessed both the horns and crest in equal degree.
