Hominin fossil evidence in the Turkana Basin in Kenya from ca. 4.1 to 1.4 Ma samples two archaic early hominin genera and records some of the early evolutionary history of Paranthropus and Homo. Stable carbon isotopes in fossil tooth enamel are used to estimate the fraction of diet derived from C3 or C4 resources in these hominin taxa. The earliest hominin species in the Turkana Basin, Australopithecus anamensis, derived nearly all of its diet from C3 resources. Subsequently, by ca. 3.3 Ma, the… Expand
Comparative isotopic evidence from East Turkana supports a dietary shift within the genus Homo
TLDR
New and published carbon and oxygen isotopic data taken from large-bodied fossil mammals, and pedogenic carbonates in fossil soils from East Turkana in northern Kenya suggest that a dietary shift from C3 to C4 resources occurred in the genus Homo circa 1.65 million years ago despite palaeoenvironmental continuity. Expand
Isotopic evidence of early hominin diets
TLDR
There is a trend toward greater consumption of 13C-enriched foods in early hominins over time, although this trend varies by region, and hominin carbon isotope ratios also increase with postcanine tooth area and mandibular cross-sectional area, which could indicate that these foods played a role in the evolution of australopith masticatory robusticity. Expand
Calcium isotopic ecology of Turkana Basin hominins
TLDR
Stable calcium isotopes recovered from fossil tooth enamel are used to compare the dietary ecology of hominins and other primates in the Turkana Basin 2-4 million years ago to expand the understanding of ancient diets. Expand
Diet of Theropithecus from 4 to 1 Ma in Kenya
TLDR
Stable isotope analyses of tooth enamel from T. brumpti and T. oswaldi in Kenya show that the earliest Theropithecus at 4 Ma had a diet dominated by C4 resources, and throughout the 4- to 1-Ma time range has a diet that is more C4-based than contemporaneous hominins of the genera Australopithecus, Kenyanthropus, and Homo. Expand
Isotopic evidence for the timing of the dietary shift toward C4 foods in eastern African Paranthropus
TLDR
Detailed carbon isotopic evidence from the hominin fossil record of the Shungura and Usno Formations, Lower Omo Valley, Ethiopia is presented, which elucidates the patterns of C4 dietary utilization in the robust hom inin Paranthropus. Expand
Dietary change among hominins and cercopithecids in Ethiopia during the early Pliocene
TLDR
It is shown that both hominins and some papionins expanded their diets to include C4 resources as early as 3.76 Ma, which indicates that the inclusion of C4 foods in hominin diet occurred as part of broader ecological changes in African primate communities. Expand
Dietary versatility of Early Pleistocene hominins
TLDR
Stable isotope and faunal data presented here document that early Homo and Paranthropus were dietary opportunists and able to cope with a wide range of paleohabitats, which clearly demonstrates their high behavioral flexibility in the African Early Pleistocene. Expand
Isotopic ecology of fossil fauna from Olduvai Gorge at ca 1.8 Ma, compared with modern fauna : research article
TLDR
The isotopic ecology and diets of fossil fauna that were present at the same time as the two fossil hominin species are described to provide a fuller understanding of their contrasting diets and of the moisture sources of their water intake. Expand
Ecosystem evolution and hominin paleobiology at East Turkana, northern Kenya between 2.0 and 1.4 Ma
TLDR
A major transition in the family Suidae is document with an increase in the abundance of fossils attributed to the Metridiochoerus lineage coeval with the local extinction of the Notochoerus family lineage and decline in abundance of the Kolpochoers lineage. Expand
Diets of mammalian fossil fauna from Kanapoi, northwestern Kenya.
TLDR
Carbon isotope ratios of mammalian teeth from the Kanapoi site in northern Kenya are interpreted in the context of C3 and C4 derived resources to investigate the paleoecology of Australopithecus anamensis to show an ecosystem that is strongly biased towards mixed feeders and browsers. Expand

Isotopic evidence of early hominin diets
TLDR
There is a trend toward greater consumption of 13C-enriched foods in early hominins over time, although this trend varies by region, and hominin carbon isotope ratios also increase with postcanine tooth area and mandibular cross-sectional area, which could indicate that these foods played a role in the evolution of australopith masticatory robusticity.

Diet of Theropithecus from 4 to 1 Ma in Kenya

Late Miocene to Pliocene carbon isotope record of differential diet change among East African herbivores
Stable isotope and molecular data suggest that C4 grasses first appeared globally in the Oligocene. In East Africa, stable isotope data from pedogenic carbonate and fossil tooth enamel suggest aExpand
Diet of Australopithecus robustus at Swartkrans from stable carbon isotopic analysis
TLDR
This work addresses the question of A. robustus diet using 13C/12C ratio analysis of structural carbonate in tooth enamel, which has been shown to retain biogenic isotopic composition over long periods, contra earlier arguments based on bone apatite. Expand
The carbon isotope ecology and diet of Australopithecus africanus at Sterkfontein, South Africa.
TLDR
It is concluded that Australopithecus africanus was highly opportunistic and adaptable in its feeding habits and that the dietary variation between individuals was more pronounced than for any other early hominin or non-human primate species on record. Expand
Dietary adaptations of extant and Neogene African suids
TLDR
The increase in size and complexity of nyanzachoere teeth reflects their exploitation of C4 vegetation, although the nyanZachoeres did not acquire their grazing habits until after contemporary perissodactyls and proboscideans had become dedicated C4 grazers. Expand
Evidence for dietary change but not landscape use in South African early hominins
TLDR
It is shown that the home range area was of similar size for species of the three hominin genera but that the dietary breadth was much higher in Australopithecus africanus than in Paranthropus robustus and early Homo, and that P. robustus relied more on plant-based foodstuffs than early Homo. Expand
Diet of Paranthropus boisei in the early Pleistocene of East Africa
TLDR
Stable isotopes are used to show that Paranthropus boisei had a diet that was dominated by C4 biomass such as grasses or sedges, which may indicate that the remarkable craniodental morphology of this taxon represents an adaptation for processing large quantities of low-quality vegetation rather than hard objects. Expand
Diet of Australopithecus afarensis from the Pliocene Hadar Formation, Ethiopia
TLDR
Stable carbon isotopic data are used to show that Australopithecus afarensis was a key participant in the C4/CAM dietary expansion by early australopiths of the middle Pliocene, and sets the stage for dietary differentiation and niche specialization by subsequent hominin taxa. Expand
Hominins, sedges, and termites: new carbon isotope data from the Sterkfontein valley and Kruger National Park.
TLDR
The consumption of C4 foods is a fundamental hominin trait that, along with bipedalism, allowed australopiths to pioneer increasingly open and seasonal environments. Expand
