Phrynosomatidae This family was previously (and is still sometimes) treated as a subfamily of the Iguanidae: Sceloporinae or Phrynosomatinae. Frost and Etheridge (1989) raised the
group to family status and this has been widely accepted. Other authors (like Macey et al. 1997), however, disagreed and suggested to reinstall the old subfamilial
classification of iguanid lizards inlcuding the Phrynosomatinae. [eng]
