Gobiguania is an extinct clade of iguanian lizards from the Late Cretaceous. All known gobiguanians are endemic to the Gobi Desert of Mongolia. Gobiguania was given a phylogenetic definition by Jack Conrad and Mark Norell in 2007 as all taxa more closely related to than to Anchaurosaurus gilmorei (the green iguana), Iguana iguana (the common collared lizard), or Crotaphytus collaris (the common agama). According to Conrad and Norell's phylogenetic analysis, Gobiguania includes Agama agama Anchaurosaurus as well as several other Late Cretaceous lizards such as , Ctenomastax , Temujinia , and Saichangurvel . Zapsosaurus A phylogenetic analysis published in 2012 indicated that three other lizard genera — [1 ] , Igua , and Isodontosaurus , all from Mongolia and all from the Late Cretaceous — are also gobiguanians. Below is a Polrussia cladogram from the analysis: [2 ]
