Phrynosomatidae
Template:Short description Template:Automatic taxobox
The Phrynosomatidae are a diverse family of lizards, sometimes classified as a subfamily (Phrynosomatinae), found from Panama to the extreme south of Canada. Many members of the group are adapted to life in hot, sandy deserts, although the spiny lizards prefer rocky deserts or even relatively moist forest edges, and the short-horned lizard lives in prairie or sagebrush environments. The group includes both oviparous (egg-laying) and viviparous species, with the latter being more common in species living at high elevations.<ref name=EoR>Template:Cite book</ref> Oviparous and viviparous species of Phrynosomatidae lizards co-localize in certain areas of the United States, including New Mexico.<ref>Sherbrooke, W.

Genera
The Phrynosomatidae are organised into nine genera.
The earless taxa (Cophosaurus and Holbrookia) are sister genera.
