2015 brief on Phrynosoma cornutum in Sonora and SE Arizona.
The Mexico Tortoise Project, 2001-2013
Phrynosoma ditmarsi, rock horned lizard in the Sierra Murrieta, eastern Sonora. Lizard found in oak woodland on a steep, fairly dense, and mesic slope.
In southern Arizona and northern Sonora, the neotropical vine snake (Oxybelis aeneus) lives in temperate oak woodland, canyon riparian woodland, desert-grassland, and pine-oak woodland communities at 1160 to 1650 m elevation. Perennial plants in an oak woodland habitat in the Atascosa Mountains in the center of the Arizona distribution of the species, have strong biogeographical affinities with the grasslands and woodlands of the southwestern United States and the northern Sierra Madre Occidental in Mexico.
This Sonoran lyresnake's eyes were bigger than it's stomach!
