Scientific name: Phrynosoma ditmarsi
The rock horned lizard, lives in northern Mexico at rocky sites in oak and oak-pine woodlands and short-tree Sinaloan deciduous forest along the western aspect of the Sierra Madre Occidental in the state of Sonora, north of Yecora, at elevations of 1050-1425 meters. This species was 'lost to science' for 65 years. After three specimens of this species were collected in Mexico near the United States border in 1890 and 1897, it was not seen again for 73 years until rediscovered in 1970 just south of the Arizona border.
