Sahelanthropus tchadensis Brunet et al., 2002 - fossil hominid from the Miocene of Chad, Africa. (replica of CNAR TM 266-01-060-1 (National Center of Research Support, Ndjamena, Chad) on public display, Field Museum of Natural History, Chicago, illinois, USA) Hominids are humans. Fossils of the human family are known back to the Miocene, with many species known from Pliocene and Pleistocene sedimentary rocks. Only one species in Family Hominidae is alive today, in the late Holocene - that's us, Homo sapiens. Hominids originated in Africa - that's where the oldest human fossils occur. Everyone on Earth is African, from an evolutionary point-of-view. This is Sahelanthropus tchadensis, a 6 to 7 million year old skull from the upper Upper Miocene of Chad in northern Africa. It has characteristics of both apes and hominids. It is considered by some researchers to be the oldest known member of Family Hominidae. Others classify it as an early ancestor to modern African apes (Family Pongidae). Sahelanthropus tchadensis has a prominent, continuous, slightly curving brow ridge above the eyes, a small braincase, and relatively small canine teeth. Classification: Animalia, Chordata, Vertebrata, Mammalia, Primates, Hominidae Stratigraphy: Upper Miocene, 6-7 Ma Locality: Toros-Menalla Quarry, western Djurab Desert, northern Chad, northern Africa |
