Three hominin fossils newly discovered at Koobi Fora, east of Lake Turkana in Kenya, will greatly improve our understanding of the early radiation of the genus Homo, clarifying the iconic but enigmatic hominin cranium KNM-ER 1470, first described by Richard Leakey in Nature in 1973. The three are an exceptionally well-preserved lower jaw (KNM-ER 60000), a fragmentary lower jaw and, importantly, a well-preserved face. At between 1.78 million and 1.95 million years old, they broadly support the idea that there were at least two contemporary Homo species, in addition to Homo erectus, in the early Pleistocene of eastern Africa. The cover shows the KNM-ER 60000 lower jaw as a photographic reconstruction together with a digital visualization of KNM-ER 1470, which probably belongs to the same species.
