Please help in Id. Is this a immature Texas Horned Lizard (which are rare here) or a mountain short (?) horned lizard. Which occurs in the Davis Mtns but have not been recorded in the Chisos Mtns. Doesn't look like a Round tail which is our more common horned lizard.

Se encontraba en un área de cambio de uso de suelo para un banco de material. Vegetación tipo matorral xerófilo-submontano

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".
