While they admit the dating of the volcanic tuff was inaccurate, F.
Fitch and colleagues claim that the depth of the specimen beneath the tuff shows a much earlier age, daing to around 2.4 myr.
1481 femora have been attributed to rudolfensis, suggesting a dramatic allometric difference, but there is much questionable about associating postcrania and cranial material together, when there is no objective sample to compare them to (an associated cranium and postcranial material). However, isolated mandibles and fragments are hard enough to attribute, and even worse when trying to attribute them to a species many researchers do not even consider a valid taxon.
Discovered by Bernard Ngeneo in 1972 at Koobi Fora in Kenya (Leakey, 1973). The braincase is surprisingly modern in many respects, much less robust than any australopithecine skull, and also without the robustness and large brow ridges typical of Homo erectus.
A lively debate over the dating of 1470 ensued (Lewin, 1987; Johanson and Edey, 1981; Lubenow, 1992).
It was originally dated at nearly 3 million years old, a figure that caused much confusion as at the time it was older than any known australopithecines, from whom habilis had supposedly descended.
The face, in contrast, is extremely large and robust.
In the last few years, an increasing number of scientists have been classifying this skull as Homo rudolfensis.
(If 1470 is related to the newly-discovered fossil WT 40000 (Kenyanthropus platyops) to which it has some claimed resemblances, it may eventually be reassigned to the genus Kenyanthropus.) Creationists seem to be fairly evenly divided on whether 1470 is an ape or a human.Originally, Gish (1979) thought it human, then later (1985) decided it was an ape.Lubenow's (1992) opinion that it was a human seemed to be gaining ground in the early 1990's, but more recently other creationists such as Mehlert (1996) and Hartwig-Scherer have decided that it is just a large-brained ape. This specimen was discovered by Richard Leakey’s team in 1972, east of Lake Turkana at Koobi Fora in northern Kenya.This discovery was of a fairly complete cranium without any remaining teeth.Due to uncertainties created by its large brain size and its early initial dates, Leakey did not attribute the specimen to a species, but simply as a member of the genus with the species indeterminate due to the large brain size and questionable morphological association with known hominids.
