The species was subsequently placed in the genus "Cercomela" introduced by Charles Lucien Bonaparte in 1856. It was moved to its current genus, "Emarginata",

The dolerite of the Great Karoo did not penetrate these rocks, so Karoo Koppies are not seen in the Little Karoo. The Little Karoo contains two other geological features that give the landscape a special character. During the erosion of the African interior following the bulging of the continent during the massive lava outpourings that ended the Karoo sedimentation 180 million years ago, some of the eroded material was
