Evidence for stone-tool-assisted consumption of animal tissues before 3.39 million years ago at Dikika, Ethiopia
The discovery of stone-tool-inflicted marks on bones found during recent survey work in Dikika, Ethiopia, extends by approximately 800,000 years the antiquity of stone tools and ofStone- tool-assisted consumption of ungulates by hominins and can now be attributed to Australopithecus afarensis.
A new hominid from the Upper Miocene of Chad, Central Africa
The discovery of six hominid specimens from Chad, central Africa, 2,500 km from the East African Rift Valley, suggest that the earliest members of the hominids clade were more widely distributed than has been thought, and that the divergence between the human and chimpanzee lineages was earlier than indicated by most molecular studies.
Geology and palaeontology of the Upper Miocene Toros-Menalla hominid locality, Chad
The fauna from Toros-Menalla site 266 suggests that S. tchadensis lived close to a lake, but not far from a sandy desert, perhaps the oldest record of desert conditions in the Neogene of northern central Africa.
A juvenile early hominin skeleton from Dikika, Ethiopia
The foot and other evidence from the lower limb provide clear evidence for bipedal locomotion, but the gorilla-like scapula and long and curved manual phalanges raise new questions about the importance of arboreal behaviour in the A. afarensis locomotor repertoire.
Isotopic biogeochemistry ( 13 C, 18 O) of mammalian enamel from African Pleistocene hominid sites
The carbon and oxygen isotope composition of carbonate in enamel hydroxylapatite can provide information on photosynthetic pathways of plants at the base of food webs, and on hydrological conditions.
The Pleistocene fauna (other than Primates) from Asbole, lower Awash Valley, Ethiopia, and its environmental and biochronological implications
The Asbole area in the Lower Awash Valley yielded a diverse fauna of large and small mammals, associated with an Acheulean industry. The most notable forms are a potentially new species of herpestid,
The Fossil Record and Evolution of Bovidae: State of the Field
The earliest records of the different bovid tribes are reviewed, along with their geographic locations, and the reinvestigation of osteological characters that might distinguish early bovids from stem taxa is investigated.

The Struthionidae and Pelagornithidae (Aves: Struthioniformes, Odontopterygiformes) from the late Pliocene of Ahl al Oughlam, Morocco
The Pliocene locality of Ahl al Oughlam is situated at the southeastern limit of the city of Casablanca, in Morocco, on an ancient seashore of the Atlantic Ocean, and has yielded a very rich vertebrate fauna including both terrestrial and marine forms.
The age of the hominin fossils from Jebel Irhoud, Morocco, and the origins of the Middle Stone Age
The ages of fire-heated flint artefacts obtained from new excavations at the Middle Stone Age site of Jebel Irhoud, Morocco, which are directly associated with newly discovered remains of H. sapiens are reported, suggest a larger scale, potentially pan-African, origin for both.
