Abstract
Recent work by Brown1, correlating the Sidi Hakoma (or Sidiha Koma2) Tuff at Hadar with Tuffs B and U-10 of the Shungura and Usno Formations, respectively, reverses a recent finding3 indicating an age of the Hadar Formation fauna of 2.9 to greater than 3.6 Myr BP. The difference in these determinations is 0.4 Myr, a significant period of evolutionary time. We compare the faunas from Shungura Unit B10, Usno and Hadar and discuss the implications for interpretation of the early hominid fossil record.
