ORDER VII 



CROCODILIA 



213 



The members of this family closely resemble modern ga vials in size and 

 general appearance, except that they have smaller heads 

 and more weakly developed fore- limbs. The principal 

 differences are to be found in the characters of the palate, 

 eustachian passages, vertebral centra, ventral armour, and 

 absence of hypapophyses in the cervical region.
