Unearthing the fossil history of Bolt’s Farm – photo essay

Bolt’s Farm, located 2.5km south-west of Sterkfontein Caves, has a wealth of animal fossil deposits of different ages, and a palaeontological history spanning 75 years.

Back in 1936, Professor Robert Broom, one of founders of palaeoanthropology in South Africa, found the first fossils at Bolt’s Farm. Over time, it has become known as the Kingdom of the Big Cats because of the discovery there of many big cat and sabre-toothed cat (Dinofelis) fossils.
