The California rock lizards are a genus (Petrosaurus) of New World lizards in the family Phrynosomatidae.[2]

Geographic range[edit]

They are endemic to southern California and Baja California, Mexico.[3]


This lizard species lives almost exclusively on rock outcrops, boulder piles, and canyon walls, where it shelters under rocks. Their habitat consists of arid and semiarid foothills and canyons along the western margin of the Colorado Desert.[4]


The courtship begins shortly after emergence in early spring. The eggs are laid around June and July.


The few predators that could pursue this lizard are collared lizards and avian predators, such as hawks, ravens, and roadrunners.


The genus Petrosaurus contains three species.
