The sungazer (Smaug giganteus, syn.Cordylus giganteus), also known as the giant girdled lizard, giant dragon lizard, ouvolk,[2] or giant zonure,[3] is the largest species of the Cordylidae, a family of lizards from sub-Saharan Africa.[4] This threatened species is endemic to Highveld grasslands in the interior of South Africa.[4] In 2011, it was assigned to the new genus Smaug, along with seven other species previously belonging to the genus Cordylus, based on a comprehensive molecular phylogeny of the Cordylidae.[5]
