Koobi Fora Research Project , Volume 6 : The Fossil Monkeys
A cercopithecoid primates first evolved in the latter part of the Miocene epoch, it was not until the Plio-Pleistocene when the two subfamilies of Old World monkeys, the colobinae and cercopithecinae, started to morphologically and ecologically diversify. This diversification is well documented in the primate fossil record, especially in the Koobi Fora Formation. In The Fossil Monkeys, which is...
متن کاملChronostratigraphy of KNM-ER 3733 and other Area 104 hominins from Koobi Fora.
A magnetostratigraphy for ∼ 60 m of Koobi Fora Formation sediment in Area 104 was derived from 46 oriented samples that produced well-resolved characteristic magnetizations from progressive thermal demagnetization. Approximately 59 m below the Morte Tuff, previously dated to ∼ 1.51 Ma (millions of years ago), the Olduvai-Matuyama boundary (∼ 1.78 Ma) was found to be at the level of marker bed A...
متن کاملStratigraphy, correlation, and age estimates for fossils from Area 123, Koobi Fora.
Geological data from the Bura Hasuma region at Koobi Fora provide important constraints for estimating the ages of hominin fossils recovered there, including the cranium KNM-ER 1813. Strata of the upper Burgi, KBS, and Okote members in this part of Koobi Fora reflect three depositional regimes driven by changing paleogeography through time. The upper Burgi and lowermost KBS sequence in the sout...
متن کاملBovids as indicators of Plio-Pleistocene paleoenvironments in east Africa.
Reconstructions of the paleoenvironments of early hominids offer a framework for understanding hominid ecological and behavioral adaptations. Habitat reconstructions typically rely upon various biological or physical habitat indicators, and here we present reconstructions of the Plio-Pleistocene paleohabitats of Koobi Fora and Olduvai Gorge as based on fossil bovids (Artiodactyla: Bovidae). Bov...
متن کاملZinc isotope ratios of bones and teeth as new dietary indicators: results from a modern food web (Koobi Fora, Kenya)
In order to explore the possibilities of using zinc (Zn) stable isotope ratios as dietary indicators, we report here on the measurements of the ratio of stable isotopes of zinc ((66)Zn/(64)Zn, expressed here as δ(66)Zn) in bioapatite (bone and dental enamel) of animals from a modern food web in the Koobi Fora region of the Turkana Basin in Kenya. We demonstrate that δ(66)Zn values in both bone ...
