Sexual dimorphism of body size in an African fossil ape, Nacholapithecus kerioi
A newly discovered galagid fossil from Nakali, an early Late Miocene locality of East Africa
The latest occurrence of the nyanzapithecines from the early Late Miocene Nakali Formation in Kenya, East Africa
The African primate fossil record is very poor between the mid-Middle and mid-Late Miocene. Nakali (~10–9.8 Ma) is one of the rare African localities that have yielded primate fossils from this period, including a new genus of great ape, Nakalipithecus nakayamai, and another large-bodied hominoid species. The Nakali primate fauna also includes small-bodied ‘apes’ and Old World monkeys (mostly colobines). In this article, we describe a new specime…
A second hominoid species in the early Late Miocene fauna of Nakali (Kenya)
Nakali is an early Late Miocene fossil locality in north-central Kenya, where the Kenya–Japan Joint Expedition team has carried out fieldwork since 2002. Previously, a large hominoid Nakalipithecus nakayamai was reported from site NA39 of this locality. In addition to Nakalipithecus, the hominoid material collected from Nakali includes an isolated P3, which shows a considerably different morphology from the P3 assigned to Nakalipithecus, suggesti…

Earliest colobine skeletons from Nakali, Kenya
Old World monkeys represent one of the most successful adaptive radiations of modern primates, but a sparse fossil record has limited our knowledge about the early evolution of this clade. We report the discovery of two partial skeletons of an early colobine monkey ( Microcolobus ) from the Nakali Formation (9.8–9.9 Ma) in Kenya that share postcranial synapomorphies with extant colobines in relation to arboreality such as mediolaterally wide dist…
Early Pleistocene Homo erectus fossils from Konso, southern Ethiopia
Homo erectus has been broadly defined to include fossils from Africa, Asia, and possibly Europe, or restricted to a supposedly confined Asian clade. Recently discovered fossils of H. erectus are allowing new insights into aspects of its evolution, such as the timing and mode of the species' emergence in Africa and its relationship to Asian populations. However, the currently available African record predating 1.0 Ma is poor, consisting of the Tur…

Hominoid fossils discovered from Chiang Muan, northern Thailand: The first step towards understanding hominoid evolution in Neogene Southeast Asia
The Thai-Japanese Paleontological Expedition Team (TJPET) has been conducting paleontological and geological fieldwork in Thailand for a number of years. In January 2000, an upper molar (CMu6-1’00) of a large-bodied Miocene hominoid was found by TJPET in a lignite mine in the Chiang Muan basin, northern Thailand. It was the first record of a Miocene hominoid from a Southeast Asian country. Two years later, TJPET found a second hominoid specimen (…
Earliest Miocene hominoid from Southeast Asia
A new hominoid fossil site, Chiang Muan in northern Thailand, yielded the first finding of a large‐bodied Miocene hominoid in Southeast Asia. This specimen (CMu6‐1′00) was preliminarily reported by Kunimatsu et al. ([ 2000a ] Primate Res. 16:299). Later, Chaimanee et al. ([ 2003 ] Nature 422:61–65) reported additional hominoid teeth from the same site, but all of them were collected from younger deposits (the Upper Lignite Member, in Nagaoka and …

The Fossil Footprints in Samburu Hills, Northern Kenya
Eighty-three mammalian footprints and 14 bird claw footprints of bird were found in the fossil site (SH-23) in Samburu Hills, northern Kenya. The site was the part of the Namurungule formation and near SH-22 where the Miocene fossil ape named Samburupithecus kiptalami was found. The footprints were left in sand sediments and a thin silt layer covered the sediments. The extent of the sediment face was not large (8×1.5 meter). The study of footprin…

The Neogene Mammalian Fauna of the Sub-Saharan Africa
The intent of this study was to show the Neogene mammalian faunal change of the sub-Saharan Africa and the Relationships of the late Miocene mammalian faunas of the sub-Saharan Africa and the Eurasia. I reviewed the Neogene mammalian fauna of the sub-Saharan Africa and studied the phylogenetic relationships of some taxa from the Namurungule Formation (late Miocene), Northern Kenya.The sub-Saharan mammalian fauna of Neogene and its environments ch…
