Pliocene Bovidae (Mammalia) from the Koro Toro Australopithecine sites, Chad

  title={Pliocene Bovidae (Mammalia) from the Koro Toro Australopithecine sites, Chad},
  author={Denis Geraads and Michel Brunet and Hassan Taisso Mackaye and Patrick Vignaud},
Abstract The Australopithecus-bearing sites of Koro Toro in central Chad yielded at least 9 species of bovids (Ruminantia: Bovidae). They all belong to genera found in North and/or East Africa, but three new species are named. Kobus korotorensis, sp. nov. is quite distinct from East African species, and is probably an early offshoot from primitive Reduncines. Kobus tchadensis, sp. nov. is more like some East African forms. Parmularius pachyceras, sp. nov. should rather be compared with a North… 

Bovidae (Mammalia) from the Lower Pliocene of Chad

The KB and KL assemblage document the gradual replacement of hippotragines by alcelaphines in Northern Chad, but it is not necessarily linked with environmental change, as all Chadian assemblages virtually lack indicators of bush or woodland like Tragelaphini and Aepyceros.

Pliocene Bovidae (Mammalia) from the Hadar Formation of Hadar and Ledi-Geraru, Lower Awash, Ethiopia

ABSTRACT We revise here the entire collection of Bovidae from the Pliocene Hadar Formation collected at Hadar and Ledi-Geraru, Lower Awash, Ethiopia. Some additions are provided to previously

A reassessment of the Bovidae (Mammalia) from the Nawata Formation of Lothagam, Kenya, and the late Miocene diversification of the family in Africa

The late Miocene Bovidae from the Nawata Formation of Lothagam were all assigned to modern tribes by Harris (2003), with the majority of specimens being referred to a species of Aepyceros, a genus

Late Pliocene Bovidae from Ledi-Geraru (Lower Awash Valley, Ethiopia) and their Implications for Afar Paleoecology

ABSTRACT Fossil bovids are described from the late Pliocene site of Ledi-Geraru, mainly from the Gurumaha and Lee Adoyta sedimentary packages (2.8–2.6 Ma). Finds include taxa already known from the

New Hippotragini (Bovidae, Mammalia) from the Late Miocene of Toros-Menalla (Chad)

Two new taxa are described from the late Miocene of Toros-Menalla in northern Chad, which yielded the earliest known hominid, Sahelanthropus tchadensis, and shares a large number of features that prompt us to classify it also at the base of the hippotragine tree, perhaps as the sister-taxon of Tchadotragus.

Two new Mio-Pliocene Chadian hominids enlighten Charles Darwin's 1871 prediction

Three Late Miocene hominids described in East Africa dated to about 7 Ma belong to a new evolutive grade distinct from Australopithecus and Homo, thus falsifying the savannah hypothesis of human origins.

Biogeographic relationships of Pliocene and Pleistocene North-western African mammals

New data on the Equus stenonis Cocchi, 1867 from the late Pliocene locality of Sésklo (Thessaly, Greece)

The equid material from the late Pliocene locality of Sesklo (Thessaly, Greece) is described and compared in this article. It belongs to a large and fairly stout Equus stenonis form, which shares



New fossils of Alcelaphini and Caprinae (Bovidae: Mammalia) from Awash, Ethiopia, and phylogenetic analysis of Alcelaphini

Alcelaphine antelopes comprise one of the most species-rich groups among the mammalian assemblages from the Middle Awash, Ethiopia, and in Africa as a whole. I describe a new genus and spec

Bovidae (Mammalia) du Pliocène final d’Ahl al Oughlam, Casablanca, Maroc

Only seven bovid species are present at Ahl al Oughlam: aTragelaphus (rare), a Bovine close toPelorovis ? praeafricanus but mostly known by teeth, a new species of kob (perhaps of an endemic

Australopithecus bahrelghazali, une nouvelle espèce d'Hominidé ancien de la région de Koro Toro (Tchad)

A mandible and first upper premolar discovered in North Chad by the Franco-Chadian Paleoanthropological Project demonstrate for the first time the presence of an australopithecine west of the Rift

Fossil Ruminants (Mammalia) from the Manonga Valley, Tanzania

An account is given of the fossil Giraffidae and of the much more abundant fossil Bovidae collected in the Manonga Valley, Tanzania, by the Wembere-Manonga Paleontological Expedition in 1990 and

Laetoli : a Pliocene site in northern Tanzania

This work presents the results of intensive fieldwork carried out from 1974 to 1981 at the site of one of the richest fossil sites yet discovered in Africa. In addition to hominid fossils, the

Tchad: un nouveau site a Hominides Pliocene

A second hominid site (KT 13) has been discovered by the MPFT (Mission Paleoanthropologique franco-tchadienne) in northern Chad and can be interpreted as representative of a mosaic landscape in a region bordering a lake or a river.

Dietary adaptations of Plio-Pleistocene Bovidae: implications for hominid habitat use.

Reconstructed diets suggest that the earliest taxa to inhabit secondary grasslands in East Africa were Connochaetes gentryi and Parmularius altidens at around 2 m.y.a.y, suggesting that adaptations to this habitat type were not related to the origin of the Hominidae or to the evolution of bipedality in hominids.

Environment and behavior of 2.5-million-year-old Bouri hominids.

The combined evidence suggests that behavioral changes associated with lithic technology and enhanced carnivory may have been coincident with the emergence of the Homo clade from Australopithecus afarensis in eastern Africa.
