Here we analyze the maxilla of two closely-related species of the Phrynosomatidae from western North America: Uta stansburiana (Common Side-blotched Lizard) and Urosaurus
ornatus (Ornate Tree Lizard).

Within Phrynosomatinae are the genera Callisaurus, Cophosaurus, Holbrookia, Phrynosoma, and Uma, and within Sceloporinae are Petrosaurus, Sceloporus, Urosaurus

Previous studies showed the importance of body temperature to color change in several species of predominantly diurnal lizards (e.g., Urosaurus
ornatus, Phrynosoma cornutum, and Sceloporus jarrovii) as a consequence of thermoregulatory issues (Sherbrooke et al.
The black-tailed brush lizard, Urosaurus
nigrieaudus (Cope, 1864), is found in a variety of habitats along the eastern side of the Peninsular Ranges from San Diego County, California, southward to the Cape Region of Baja California (Grismer 2002).
