During the release of the lizards, the CCR team found two horned lizards that they believe came from a prior release. They also found scat samples that will be sent to Texas Christian University for analysis. The team also found a sub-adult near the release site, which the team believes shows that prior released lizards are breeding successfully in the wild. An adult horned lizard was found on an adjacent property to the release site, across a county road, which the team says indicates that the reptiles are dispersing. This is a positive sign for the center’s goals of expanding the range of these reptiles.

Texas Horned Lizard Information

Horned lizards (Phrynosoma), often called “horny toads” or “horned frogs” are quite possibly the most gregarious genus of lizard species in North America. Of the 15 known horned lizard species in the United States, the Texas horned lizard is the most widely distributed. Once abundant in much of the Southwest, the Texas horned lizard has disappeared from much of its range in Texas and Oklahoma. It is listed as Threatened by the state. This is due to a variety of factors, including loss of habitat, planting of non-native grasses, conversion of land to pastureland and agricultural use, and the introduction of the invasive fire ant, which preys upon the native ants that horned lizards require to survive. These little dinosaurs do not make good pets because they require a steady diet of harvester ants.
