Many thanks to Hank for alerting me to the presence of this species up there! I'm sure I never would have noticed they weren't fence lizards on my own.
Relict population up here not seen by many. I've seen it now at Antioch Dunes and here.
On summit of Mt. Diablo. This is a relic population found only on the main peak and North Peak. Preliminary DNA tests suggest they are most closely related to the population in Yolo County. Note the cell size. See Sceloporus occidentalis observation for comparison.
The sagebrush lizard (Sceloporus graciosus) is a common species of phrynosomatid lizard found at mid to high altitudes in the western United States of America. It belongs to the genus Sceloporus (spiny lizards) in the Phrynosomatidae family of reptiles. Named after the sagebrush plants near which it is commonly found, the sagebrush lizard has keeled and spiny scales running along its dorsal surface.
