Urosaurus

Urosaurus is a genus of lizards, commonly known as tree lizards or brush lizards, belonging to the New World iguanid subfamily Phrynosomatinae. Species in the genus Urosaurus can be distinguished from members of the genus Sceloporus by the presence of a gular (under neck) fold and granular lateral scales. They can be distinguished from members of the genus Uta by the presence of enlarged (sometimes only slightly) dorsal scales.

Urosaurus have been used as a model system in lizard life-history studies, and populations produce two or more clutches of eggs per year. Field studies have also shown a cost of reproduction in a natural New Mexico population of the species Urosaurus ornatus.
