Fossilised footprints are found on many Karoo farms, and on Gansfontein, near Fraserburg, there is an intriguing palaeo-surface. It shows an ancient flood-plain surface with contour, mud, ripple and wrinkle marks, as well as worm trails, fish-fin imprints and anthropoid trails. There are also many large mammal-like reptile, Dinocephalian and Bradysaurus tracks.
There is a complete Bradysaurus fossil, restored in situ, on Melton Wold, near Loxton. These huge, lizard-like, plant-eating reptiles were once as plentiful 260 million years ago as springbok are now.
