Urosaurus ornatus, commonly known as the ornate tree lizard, is a species of lizard in the family Phrynosomatidae. The species is native to the southwestern United States and northwestern Mexico. The species, which was formerly called simply the "tree lizard", has been used to study physiological changes during the fight-or-flight response as related to stress and aggressive competition. Its life history and costs of reproduction have been documented in field populations in New Mexico and Arizona. This species has been fairly well studied because of its interesting variation in throat color in males that can correlate with different reproductive strategies,

Its habitat is shortgrass prairie, desert areas with scrub and arid shrubland. The species is named to honor Clinton Hart Merriam, a biologist who first described several other members of the genus Perognathus, and first elucidated the principle of a "life zone" as a means of characterizing ecological areas with similar plant and animal communities.
Wyoming is home to 12 amphibian species and 22 species of reptiles.
Sceloporus virgatus, commonly known as the striped plateau lizard, is a species of lizard within the genus Sceloporus. This genus is known for the signaling modalities that it uses and exhibits, including visual motion and chemical signals that aid in identifying their territories as well as color that indicates aggression.
