"Toumai" (of the species Sahelanthropus tchadensis
) is around 7 million years old and is considered by some paleontologists to be the first representative of the human lineage.

On a dig in central Africa, a French paleontologist's team discovered the head bone and jaw of Sahelanthropus tchadensis
, a 'hominid' or human-like creature that would have existed seven million years ago.
"This is the case for early hominin species such as Sahelanthropus tchadensis
, which shows a forward shift of the foramen magnum but has aroused some controversy as to whether it is more closely related to humans or African apes." Ee Ee Ee
9:15 PHYLOGENETIC RELATIONSHIPS BETWEEN THE UPPER MOLARS OF SAHELANTHROPUS TCHADENSIS
AND LATE MIOCENE HOMINOIDS AND HOMINIDS **.
Anthropologists working in Chad describe a fossil skull more than 6 million years old of Sahelanthropus tchadensis
, which maybe the oldest known human ancestral species (7/13/02,p.
Other possible contenders for the earliest proto-human fossil are Sahelanthropus tchadensis
, a skull found in Chad (Brunet et al., 2002), from about 6-7 mya with a puzzling mixture of features making it difficult to classify, and Orrorin tugenensis (Senut et al., 2001) just below 6 million years old, found in Kenya.
A more recently identified hominid genus and species, Sahelanthropus tchadensis
, may have lived 7 million years ago.
Tambien en un principio se consideraron como los <<primeros hominidos>> al genero Sahelanthropus tchadensis
con 6 a 7 millones de anos y tambien el genero Orrorin tugenensis, pero por lo fragmentario de sus restos y morfologia dentaria no han sido incluidos como tales.
En 2001, en Republica de Chad, pais africano, se descubrio el que parecia ser el fosil mas antiguo de un antepasado humano, al que los cientificos llamaron Sahelanthropus tchadensis
, pero que coloquialmente se le llamo Toumai, nino en el lenguaje local.
Because the skull resembled no known species, the discoverers classified it in a new genus and species, naming it Sahelanthropus tchadensis
. But the fossil is nicknamed Toumai, meaning "hope of life" in a Chadian language.
Toumai - of the newly dubbed species Sahelanthropus tchadensis
- could be as much as 1m years older than previously found hominid fossils, and at least 3m years older than the next-oldest hominid skulls.
