Round-tailed Horned Lizard
Persimmon Gap Road
Big Bend National Park
Brewster County, TX
22 June, 2012
This pair was found together, exactly as you see in the second and third photos. I love their cryptic pattern, and they way they act like stones. In this area there were both red and white stones.
AOR, released in original location
Visible damage to supraocular scales to left eye. Blood was dry.
Injured on Road, blood around mouth, with dried tissue (tongue?) sticking out. Animal was BAR (bright, alert, responsive) however. Possibly hit by white F150 that had passed quite some miles back (only vehicle to pass me heading south after having turned onto US 385 south at Marathon; no vehicles passed me heading north).
The roundtail horned lizard (Phrynosoma modestum) is one of the smaller species of horned lizard. Their specific epithet is from the Latin word modestum, meaning modest or calm. They are found in the United States, in western Texas, New Mexico eastern Arizona, southeastern Colorado and eight states in northcentral Mexico where they are referred to as "tapayaxtin".
