Diet of the Indochinese silvered langur ( Trachypithecus germaini ) in Kien Luong Karst area, Kien Giang Province
The Indochinese silvered langur ( Trachypithecus germaini ) is distributed to the west of Mekong River in Cambodia, Lao PDR, Thailand and Vietnam. During a two‐year study, from May 2014 to May 2016, we collected 320.44 hr of behavior, with 17,040 feeding bouts recorded (142 hr) for T. germaini on Chua Hang Karst Mountain, Kien Luong District, Kien Giang Province, Vietnam. Feeding accounted for 45% of the Indochinese silvered langurs’ activity bud…

An anatomical and mechanical analysis of the douc monkey (genus Pygathrix ), and its role in understanding the evolution of brachiation
OBJECTIVES: Pygathrix is an understudied Asian colobine unusual among the Old World monkeys for its use of arm-swinging. Little data exists on the anatomy and mechanics of brachiation in this genus. Here, we consider this colobine to gain insight into the parallel evolution of suspensory behavior in primates. MATERIALS AND METHODS: This study compares axial and appendicular morphological variables of Pygathrix with other Asian colobines. Addition…

Learning the ropes: The ontogeny of locomotion in red-shanked douc (Pygathrix nemaeus), Delacour's (Trachypithecus delacouri), and Hatinh langurs (Trachypithecus hatinhensis) I. positional behavior
Recent studies at the Endangered Primate Rescue Center (EPRC) in the Socialist Republic of Vietnam's Cuc Phuong National Park by Byron et al. ([2002] Am. J. Phys. Anthropol. [Suppl.] 34:51) and Covert and Byron ([2002] Caring for Primates) revealed unexpected locomotor and postural behaviors in the red-shanked douc langur (Pygathrix nemaeus). This paper further elucidates the question of red-shanked douc suspensory behavior, and provides initial …

New skeletal remains of Omomys(Primates, Omomyidae): Functional morphology of the hindlimb and locomotor behavior of a Middle Eocene primate
New body mass estimates forOmomys carteri, a middle Eocene primate from North America
We report new body mass estimates for the North American Eocene primate Omomys carteri. These estimates are based on postcranial measurements and a variety of analytical methods, including bivariate regression, multiple regression, and principal components analysis (PCA). All body mass estimation equations show high coefficients of determination (R2), and some equations exhibit low prediction errors in accuracy tests involving extant species of b…

Recently Recovered Specimens of North American Eocene Omomyids and Adapids and Their Bearing on Debates about Anthropoid Origins
New early Eocene anaptomorphine primate (Omomyidae) from the Washakie Basin, Wyoming, with comments on the phylogeny and paleobiology of anaptomorphines
Recent paleontological collecting in the Washakie Basin, southcentral Wyoming, has resulted in the recovery of over 100 specimens of omomyid primates from the lower Eocene Wasatch Formation. Much of what is known about anaptomorphine omomyids is based upon work in the Bighorn and Wind River Basins of Wyoming. This new sample documents greater taxonomic diversity of omomyids during the early Eocene and contributes to our understanding of the phylo…

Biomechanical association of dental and temporomandibular pathology in a medieval Nubian population
An analysis of the relationship between oral pathology and degenerative change at the temporomandibular joint (TMJ) was undertaken on an archaeological sample of 122 adult crania from the Medieval site of Kulubnarti in Sudanese Nubia. The crania were sorted into 2 groups: those demonstrating clearly visible bony changes at the joint (TMJ+) and those without visible change (TMJ−). These groups were compared according to 1) age; 2) sex; 3) active d…

Phylogenetic relationships among the Notharctinae of North America
Study of over 1,000 specimens representing all notharctine genera and species leads to the conclusion that current concepts about the relationships of genera within the Notharctinae are incorrect. The following describes the more probable relationships among these genera. 1) Smilodectes and Notharctus are more closely related to each other than either is to any known early Eocene notharctine. Synapomorphies linking these genera include relatively…

Ontogenetic, intraspecific, and interspecific variation of the prehallux in primates: Implications for its utility in the assessment of phylogeny
The prehallux is a sesamoid bone occurring in the region of the hallucial tarso‐metatarsal joint in a number of metatherian and eutherian orders and in some nonmammalian tetrapods. Within the order Primates, it occurs invariably in ceboids and Hylobates , with extreme infrequency in pongids and Homo , and is absent in other primates groups. It has been suggested that, first, the prehallux is homologous both within and across the infraclasses Meta…
True grit: A microwear experiment
Recently we noted the effects of experimental diets on microscopic dental wear in the American opossum and concluded that it might prove difficult to distinguish the microwear produced by an insectivorous diet from that produced by some kinds of herbivorous ones. We also noted that wear caused by gritty diets and those containing plant opal, although they might be confused with one another, are easily distinguished from other sorts of dietary wea…
Dental microwear and diet: Implications for determining the feeding behaviors of extinct primates, with a comment on the dietary pattern of Sivapithecus
Dental microwear is of special interest for two reasons. First, it has been proposed that specific dental microwear patterns are associated with specific diets and therefore that the diets of extinct forms may be deduced by analysis of microwear. Second, it has been suggested that the geometry of wear striations indicates the direction of masticatory movement. We tested these ideas by analyzing microwear of laboratory animals fed different diets.…

Paleoprimatological research over the last 50 years: Foci and trends
Since 1930 the approach to fossil primates has undergone a twofold revolution, in more advanced taxonomic thinking, and in the growth of studies relating living primates to the interpretation of past forms. Great strides have also been made in discovering primate fossils–in 1930 there were some 58 genera of extinct primates known, and since then more than 65 new genera have been named. A major aspect of paleoprimatological research today is multi…
