All six known specimens of the early hominid Sahelanthropus tchadensis come from Toros-Menalla site 266 (TM 266), a single locality in the Djurab Desert, northern Chad, central Africa. Here we present a preliminary analysis of the palaeontological and palaeoecological context of these finds. The rich fauna from TM 266 includes a significant aquatic(More)
Recently Angst et al. (2011) proposed a new mean body mass estimate for the dodo (Raphus cucullatus), of Mauritius Island, 10.2 kg, which is at the lower end of previous estimated intervals such as Kitchener's (1993). We question both their methods and results and propose a revised estimated interval. Angst et al. (2011) used the lengths of the hindlimb(More)
The bird fossil record is globally scarce in Africa. The early Tertiary evolution of terrestrial birds is virtually unknown in that continent. Here, we report on a femur of a large terrestrial new genus discovered from the early or early middle Eocene (between ∼52 and 46 Ma) of south-western Algeria. This femur shows all the morphological features of the(More)
Recent data accumulated from fields as varied as avian palaeontology, palaeobotany, historical biogeography and molecular phylogenetics provide a completely renewed picture of the origin, evolution and distribution of modern birds. Although the origin of birds is still controversial, their Tertiary history is now well known. The reconstruction of(More)
Two groups of flightless ratite birds existed in New Zealand during the Pleistocene: the kiwis and the moas. The latter are now extinct but formerly included 11 species. We have enzymatically amplified and sequenced approximately 400 base pairs of the mitochondrial 12S rRNA gene from bones and soft tissue remains of four species of moas as well as eight(More)
Hummingbirds (Trochilidae) today have an exclusively New World distribution, but their pre-Pleistocene fossil record comes from Europe only. In this study, we describe an exceptionally preserved fossil hummingbird from the early Oligocene of southeastern France. The specimen is articulated, with a completely preserved beak and feathering. Osteological(More)
A distal tarsometatarsus and a fragment of carpometacarpus of a small galliform, the size of a recent quail, have been found in the late Early or early Middle Eocene of Chambi, in Tunisia. Although a large number of stem group representatives of Galliformes are known from the Eocene of the Northern Hemisphere, and one from the middle Eocene of Namibia, the(More)
Abtract: 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. It has yielded a very rich vertebrate fauna (macroand micromammals, birds, reptiles, amphibians and fishes) including both terrestrial and marine forms. On the basis of biostratigraphy,(More)
SYNOPSIS The first complete skeletons of the early Eocene avian taxon Primobucconidae Brodkorb, 1970aredescribedand theosteologyandsystematic positionof thesepoorly knownbirdsare revised. New specimens from Germany (Messel) and France (Condé-en-Brie) are the first Old World records of this taxon. From Messel, two new species, Primobucco perneri sp. nov. and(More)
An almost complete tarsometatarsus from the middle Eocene locality of Silica South, Sperrgebiet, Namibia, is attributed to the order Galliformes. This is the earliest record of the order in Africa. It belongs to a stem group galliform and differs from the Recent families. It is compared with Mesozoic birds from America, and Gallinuloididae,(More)
