The banded rock lizard (Petrosaurus mearnsi) is a species of phrynosomatid lizard.
Etymology
The specific name, mearnsi, is in honor of American naturalist Edgar Alexander Mearns, who collected the first specimens.[2][3]

It has a single black collar, a banded tail, and granular scales on its body, with keeled tail and limb scales. Individuals may be 6.2 to 8.7 cm (2.4 to 3.4 in) long snout-to-vent. Males have more pronounced throat patterns and brighter blue coloring than females.
