Foods derived from C4 plants were important in the dietary ecology of early Pleistocene hominins in southern and eastern Africa, but the origins and geographic variability of this relationship remain unknown. Carbon isotope data show that Australopithecus bahrelghazali individuals from Koro Toro in Chad are significantly enriched in 13C, indicating a dependence on C4 resources. As these sites are over 3 million years in age, the results extend the pattern of C4 dependence seen in Paranthropus…

Dietary change among hominins and cercopithecids in Ethiopia during the early Pliocene
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.
Isotopic evidence of early hominin diets
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.
Fossil herbivore stable isotopes reveal middle Pleistocene hominin palaeoenvironment in ‘Green Arabia’
Stable carbon and oxygen isotope analysis of mammal teeth associated with stone tools and cut-marked bone dated to between 300,000 and 500,000 years ago reveals that, at the time of the earliest-known hominin presence, the Arabian peninsula was home to productive grasslands similar to modern-day African savannahs.

Calcium isotopic ecology of Turkana Basin hominins
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.
Dietary versatility of Early Pleistocene hominins
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.
Diet of Australopithecus afarensis from the Pliocene Hadar Formation, Ethiopia
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.

Herbivore paleodiet and paleoenvironmental changes in Chad during the Pliocene using stable isotope ratios of tooth enamel carbonate
Abstract Chad is a key region for understanding early hominid geographic expansion in relation to late Miocene and Pliocene environmental changes, owing to its location 2500 km west from the Rift
Stable isotopes in fossil hominin tooth enamel suggest a fundamental dietary shift in the Pliocene
It is argued that evidence for engagement with C4 food resources may mark a fundamental transition in the evolution of hominin lineages, and that the pattern had antecedents prior to the emergence of Australopithecus africanus.
Diet of Paranthropus boisei in the early Pleistocene of East Africa
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.
Diet of Australopithecus robustus at Swartkrans from stable carbon isotopic analysis
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.

The morphological adaptations of mammalian assemblages found with early hominids are used to reconstruct the habitat based on each species' ecological adaptations, thus minimizing problems introduced by taxonomy and taphonomy.
What Insights Can Baboon Feeding Ecology Provide for Early Hominin Niche Differentiation?
The absence of a fixed-diet in papionins implies that it was unlikely that the more ecologically flexible hominins evolved specializations for any one food type, an interpretation consistent with recent carbon isotope, dental microwear, and ecomorphological studies.
