Here are two maps showing the ranges of the Texas Horned Lizard. The map on the left shows the native range which stretches from Kansas to the Northern part of Mexico and from Louisiana to Arizona (Todd). They like to live in sand that is very warm, because most things in their life depend on thermoregulation, so the hot sand of deserts is an idea spot for the them to live (Manaster). The map on the right shows where some Texas Horned Lizards live now, because they use to be common as pets and now they have been introduced into places that weren't native like parts of South Carolina and Georgia where sand dunes are similar to their normal desert-like conditions (Lizards of South Carolina and Georgia).
