The banded rock lizard (Petrosaurus mearnsi) is a species of phrynosomatid lizard.[2]
Etymology
The specific name, mearnsi, is in honor of American naturalist Edgar Alexander Mearns, who collected the first specimens.[3][4]
Geographic range
It is endemic to extreme southern California and Baja California, Mexico.[5] It also occurs on Isla El Muerto.[1]
Description
Petrosaurus mearnsi is an extremely flat-bodied lizard. Its dorsum is olive, brown or gray, with white or bluish spots. 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.[6]
Habitat
These lizards are associated with boulder hillsides,[6] extending in Baja California to chaparral and pinyon-juniper woodlands.[1]
Diet
They are omnivorous, feeding not only on insects and spiders, but also on buds and flowers.[7]
Reproduction
Gravid females lay eggs from June through August. Clutch size varies from 2 to 6 eggs.[7]
