5- The rock horned lizard or Ditmars' horned lizard (Phrynosoma ditmarsi)
From Wikipedia, the free encyclopedia
The rock horned lizard or Ditmars' horned lizard (Phrynosoma ditmarsi) is a species of phrynosomatid lizard endemic to Sonora in northern Mexico, south of the Arizona border. Bearing the shortest horns of all the horned lizards, it lives in thorn-scrub and deciduousSinaloan woodlands. The rock horned lizard was "lost" to science for about 65 years. It has a unique habitat preference and limited distribution. It also had a very imprecise holotype locality record which made it difficult to locate. An extraordinary effort by Vincent Rothbased on a cross-correlational analysis of gut contents from only three specimens led to its rediscovery.
