TABLE 8. Polarity Inferences for Lower-level Analysis Using Brachylophus and 

 Dipsosaurus as Outgroups 



Note: Character-state codes correspond with those in the list of systematic characters. 

 Polarity codes are as follows: 0, plesiomorphic; 1, apomorphic; 2, derived from 1.

 characters, and is presented with the characters recoded to eliminate variation within the 

 basic taxa (Table 9).
