<P> Smith Woodward decided the fossils represented an extinct hominin species as the "...thick skull, sloped forehead and giant brow ridges made the species distinct from living people". The finds were dated between 300,000 and 125,000 years BC . "However, this (African) group of fossils has (also) been known by many other now - obscure names", none ever having been accepted universally, including the taxon Homo rhodesiensis . The Saldanha cranium, found in 1953 in South Africa was subject to at least three taxonomic revisions from 1955 to 1996 . Consensus is confined to informal taxonomic categories, such as "pre-modern". </P> <P> Most scientists now regard Homo rhodesiensis as such the direct ancestor of anatomically modern humans . </P> <P> Kabwe 1, also called the Broken Hill skull, was assigned by Arthur Smith Woodward in 1921 as the type specimen for Homo rhodesiensis; most contemporary scientists forego the taxon "rhodesiensis" altogether and assign it to Homo heidelbergensis . The cranium was discovered in Mutwe Wa Nsofu Area in a lead and zinc mine in Broken Hill, Northern Rhodesia (now Kabwe, Zambia) on June 17, 1921 by Tom Zwiglaar, a Swiss miner . In addition to the cranium, an upper jaw from another individual, a sacrum, a tibia, and two femur fragments were also found . The skull was dubbed "Rhodesian Man" at the time of the find, but is now commonly referred to as the Broken Hill skull or the Kabwe cranium . </P> <P> The association between the bones is unclear, but the tibia and femur fossils are usually associated with the skull . Rhodesian Man is dated to be between 125,000 and 300,000 years old . Cranial capacity of the Broken Hill skull has been estimated at 1,230 cm3 . Bada, & al., (1974) published the direct date of 110 ka for this specimen measured by aspartic acid racemisation . The destruction of the paleoanthropological site has made layered dating impossible . </P>
