Kabwe skull (Broken Hill skull)

Definition: 

A fossilized human cranium dated to approximately 300,000–125,000 years ago, that was discovered in 1921 in Kabwe (formerly Broken Hill), Zambia. It is classified as Homo heidelbergensis or sometimes as an archaic Homo sapiens. The skull has a large braincase of about 1,230 cubic centimeters but also retains robust features, such as a prominent brow ridge, broad face, and thick cranial bones. The Kabwe Skull may represent a transitional form between Homo erectus and later anatomically modern humans.
