Regal Horned Lizard
Phrynosoma solare

Pima Co., Arizona -  August 3rd, 2000
 

On dirt roads out in the low desert, searching for sidewinders, we ran across several solare, as the sun was setting.  We managed to slap hands on one, even though it was as hot as an oven and the lizards were very active.  These are the largest of the Horned Lizards, and also have the most impressive set of spines around the back of the head.
