While not a keystone species, horned lizards might be considered charismatic microfauna—so culturally significant that losing them would be like losing a crucial piece of what makes Texas Texas. These prehistoric-looking wildlife celebrities adorn airplane tails and license plates, murals and postcards. They’ve been the official state reptile since 1993. In the town of Eastland (population 3,613), you can even visit the tiny tomb of Texas’s most famous horned lizard, Ol’ Rip (as in Rip van Winkle), who inspired the Looney Tunes dancing frog character and supposedly survived 31 years in a time capsule.
