Subspecies and sexual craniofacial size and shape variations in Japanese macaques ( Macaca fuscata)
Adaptation to various environments leads to evolutionary change in size and shape in nonhuman primates.In island environments, larger mammals tend to be smaller compared with the original mainland population.The Japanese macaque (Macaca fuscata) has two subspecies: Macaca fuscata yakui (MFY) on Yakushima Island, and Macaca fuscata fuscata (MFF) on the main Japanese archipelago.Since adult shape differences reflect spatiotemporal developmental pat…
First discovery of colobine fossils from the Late Miocene/Early Pliocene in central Myanmar
Prenatal ontogeny of subspecific variation in the craniofacial morphology of the Japanese macaque (Macaca fuscata)
Femur length, body mass, and stature estimates of Orrorin tugenensis, a 6 Ma hominid from Kenya
Distal humerus and ulna of Parapresbytis (Colobinae) from the Pliocene of Russia and Mongolia: Phylogenetic and Ecological Implications Based on Elbow Morphology
Parapresbytis eohanuman is a colobine known from two middle Pliocene localities southeast of Lake Baikal, northern East Asia. This study examined the morphology of postcranial specimens, a distal humerus and an ulna, of Parapresbytis. A total of 18 and 13 linear measurements were taken from the humerus and the ulna, respectively, and compared with those of extant and European fossil colobines using principal components analysis. The distal humera…
Postcranial bones of infant Nacholapithecus: Ontogeny and Positional Behavioral Adaptation
We describe the postcranial bones of a partial skeleton of a male infant Nacholapithecus kerioi (KNM-BG 37800) from the Middle Miocene of Kenya. The skeletal elements are associated with dental remains and its age is presumed to be 6–15 months based on a comparison with an infant Proconsul heseloni with a similar dental growth stage. The postcranial elements include the left scapula, a lumbar vertebra, left distal humerus, right proximal ulna, ri…

Variation in maxillary sinus anatomy among platyrrhine monkeys
A new eosimiid from the latest middle Eocene in Pondaung, central Myanmar
A new species of eosimiid primate, cf. Eosimias paukkaungensis sp. nov., from the latest middle Eocene of Pondaung, central Myanmar is described. The specimen consists of left and right mandibular fragments preserving only the M3, so that its generic status is provisional. The cf. E. paukkaungensis fossil is much larger than homologues of the two Eosimias species from China. It is too large to be a mandible for the taxa represented by the Eosimia…
Stratigraphy of the primate-bearing beds of the Eocene Pondaung Formation at Paukkaung area, Myanmar
We report on the stratigraphy of the 'Upper Member' of the middle Eocene Pondaung Formation at Paukkaung area (central Myanmar), with an emphasis on horizons that have yielded primate fossils. Deposits from the Paukkaung area of the Pondaung Formation have yielded many primate fossils at localities Pk1, Pk2, Pk3, and Pk5. The primate-bearing beds of these localities correspond to horizons of almost the same stratigraphic level. This was confirmed…
Body Mass Estimates for Eocene Eosimiid and Amphipithecid Primates Using Prosimian and Anthropoid Scaling Models
Geographical and body size distributions of the Pondaung primates with a comment on the taxonomic assignment of NMMP 20, postcranium of an amphipithecid
Relative abundance and body size were compared among six primate genera found from the Pondaung Formation (latest middle Eocene, Myanmar). Pondaungia, consisting of two species, is the most common primate in the Pondaung fauna. A high abundance of Pondaungia savagei, the larger species, is recorded at the northern fossil localities (Mogaung area). At the southwestern localities (Bahin area), the primates are taxonomically more diverse than in the…
