Middle Pliocene hominin species diversity has been a subject of debate over the past two decades, particularly after the naming of Australopithecus bahrelghazali and Kenyanthropus platyops in addition to the well-known species Australopithecus afarensis. Further analyses continue to support the proposal that several hominin species co-existed during this time period. Here we recognize a new hominin species (Australopithecus deyiremeda sp. nov.) from 3.3–3.5-million-year-old deposits in the… Expand

Palaeoanthropology: The middle Pliocene gets crowded
TLDR
Another Middle Pliocene hominin, Australopithecus deyiremida, is described, which lived in Ethiopia at around the same time as Australipithecus afarensis ('Lucy') and other species such as Kenyanthropus platyops in Kenya and its morphology suggests that some dental features traditionally associated with later genera such as Paranthropus and Homo emerged earlier than previously thought. Expand
The Pliocene hominin diversity conundrum: Do more fossils mean less clarity?
TLDR
A closer look at the currently available fossil evidence from Ethiopia, Kenya, and Chad indicates that Australopithecus afarensis was not the only hominin species during the middle Pliocene, and that there were other species clearly distinguishable from it by their locomotor adaptation and diet. Expand
A 3.8-million-year-old hominin cranium from Woranso-Mille, Ethiopia
TLDR
A nearly complete hominin cranium from Woranso-Mille (Ethiopia) that is date to 3.8 million years ago is described, providing the first glimpse of the entire craniofacial morphology of the earliest known members of the genus Australopithecus. Expand
Introduction to KSD-VP-1/1: The Earliest Adult Partial Skeleton of Australopithecus afarensis
TLDR
This edited volume provides the taphonomy and paleoecology of the partial skeleton, as well as detailed comparative descriptions of the preserved elements of KSD-VP-1/1 and their implications for the understanding of early hominin paleobiology. Expand
New Pliocene hominin remains from the Leado Dido'a area of Woranso-Mille, Ethiopia.
TLDR
These fossils suggest that at least one additional hominin lineage lived alongside A. afarensis in the Afar Depression and demonstrate that the large range of variation accepted for this species is present even within a limited spatiotemporal range. Expand
Potential hominin affinities of Graecopithecus from the Late Miocene of Europe
TLDR
The examination of its previously unknown dental root and pulp canal morphology confirms the taxonomic distinction from the significantly older northern Greek hominine Ouranopithecus and shows features that point to a possible phylogenetic affinity with hominins. Expand
Hominin dental remains from the Pliocene localities at Lomekwi, Kenya (1982-2009).
TLDR
Dental remains from Lomekwi (West Turkana, Kenya), which date from between 3.2 and 3.5 Ma, are described and it cannot be determined whether these LomeKwi specimens should be attributed to Kenyanthropus platyops, but some dental characters differentiate this sample from these species. 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
Comparative description and taxonomy of new hominin juvenile mandibles from the Pliocene of Woranso-Mille (Central Afar, Ethiopia).
TLDR
Two recently discovered Pliocene hominin juvenile mandibles from Woranso-Mille, that have been radioisotopically dated to 3.6 million years ago, are described and assigned to Australopithecus afarensis based on their possession of mandibular morphological features considered as distinctive of the species. Expand
Middle Pliocene hominin distribution patterns in Eastern Africa.
TLDR
It is suggested that Kenyanthropus platyops and Australopithecus afarensis inhabited similar types of habitats across different rift basins, contributing to a growing body of evidence suggesting that early hominins diverged from their great ape counterparts by abandoning woodland-dominated habitats.

New hominin genus from eastern Africa shows diverse middle Pliocene lineages
TLDR
New fossils discovered west of Lake Turkana, Kenya, which differ markedly from those of contemporary A. afarensis point to an early diet-driven adaptive radiation, provide new insight on the association of hominin craniodental features, and have implications for the understanding of Plio–Pleistocene hom inin phylogeny. Expand
A new species of the genus Australopithecus (Primates: Hominidae) from the Pliocene of eastern Africa
TLDR
Careful evaluation of the material has led to the recognition of a distinctive suite of morphological traits distinguishing the Laetolil and Hadar remains from other hominid taxa, indicating the necessity of assigning these fossils to a new and more primitive species of Australopithecus. Expand
A new hominin foot from Ethiopia shows multiple Pliocene bipedal adaptations
TLDR
New pedal elements from a newly discovered partial hominin foot skeleton from eastern Africa show that new pedal elements belong to a species that does not match the contemporaneous Australopithecus afarensis in its morphology and inferred locomotor adaptations, but instead is more similar to the earlier Ardipithecus ramidus in possessing an opposable great toe. Expand
Australopithecus garhi: a new species of early hominid from Ethiopia.
TLDR
Discovery of 2.5 Ma hominid cranial and dental remains from the Hata beds of Ethiopia's Middle Awash allows recognition of a new species of Australopithecus, descended from Australipithecus afarensis and is a candidate ancestor for early Homo. Expand
Hominin diversity in the Middle Pliocene of eastern Africa: the maxilla of KNM-WT 40000
TLDR
The results of statistical analyses show that the attribution of KNM-WT 40000 to a separate species and the notion that hominin taxonomic diversity in Africa extends back well into the Middle Pliocene are supported. Expand
New fossils of Australopithecus anamensis from Kanapoi, West Turkana, Kenya (2003-2008).
TLDR
Nine new Kanapoi hominin fossils support the observation that canine crown height, morphology, root size and dimorphism were not altered from a primitive ape-like condition as part of a single event in human evolution, and that there may have been an adaptive difference in canine function between A. anamensis and A.afarensis. Expand
New four-million-year-old hominid species from Kanapoi and Allia Bay, Kenya
TLDR
The mosaic of primitive and derived features shows this species to be a possible ancestor to Australopithecus afarensis and suggests that Ardipithecus ramidus is a sister species to this and all later hominids. Expand
Asa Issie, Aramis and the origin of Australopithecus
TLDR
New fossils from the Middle Awash study area that extend the known Au. Expand
"Lucy" redux: a review of research on Australopithecus afarensis.
TLDR
The discovery and naming of A. afarensis coincided with important developments in theory and methodology in paleoanthropology; in addition, important fossil and genetic discoveries were changing expectations about hominin divergence dates from extant African apes. Expand
New fossils from Koobi Fora in northern Kenya confirm taxonomic diversity in early Homo
TLDR
Three newly discovered fossils are reported on that clarify the anatomy and taxonomic status of KNM-ER 1470 and confirm the presence of two contemporary species of early Homo, in addition to Homo erectus, in the early Pleistocene of eastern Africa. Expand
