Open encyclopedia reference
The sungazer (Smaug giganteus, syn. Cordylus giganteus), also known as the giant girdled lizard, giant dragon lizard, ouvolk, or giant zonure, is the largest species of the Cordylidae, a family of lizards from Sub-Saharan Africa. This threatened species is endemic to Highveld grasslands in the interior of South Africa. 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.
