A new Pitheciin primate from the middle Miocene of Argentina
We report here a new fossil primate from the middle Miocene of Argentina. The material consists of isolated teeth, mandibular fragments, and a talus. The fossils were collected in the Collón Cura formation at Cañadón del Tordillo in Neuquén Province. An age of 15.71 +/- 0.07 Ma has been reported for the Pilcaniyeu Ignimbrite, which lies just below the paleosols in which the fossils were found. This material is thus the youngest occurrence of foss…
Nuciruptor rubricae, a new Pitheciin seed predator from the Miocene of Colombia
A new genus and species of platyrrhine primate, Nuciruptor rubricae, are added to the increasingly diverse primate fauna from the middle Miocene of La Venta, Colombia. This species displays a number of dental and gnathic features indicating that it is related to living and extinct Pitheciinae (extant Callicebus, Pithecia, Chiropotes, Cacajao, and the Colombian middle Miocene Cebupithecia sarmientoi). Nuciruptor is markedly more derived than Calli…

Hindlimb suspension and hind foot reversal in Varecia variegata and other arboreal mammals
The foot, perhaps more than any other region of the primate body, reflects the interaction of positional behaviors with the geometric properties of available supports. The ability to reverse the hind foot during hindlimb suspension while hanging from a horizontal support or descending a large diameter vertical trunk has been noted in many arboreal mammals, including primates. Observations of Varecia variegata in the wild and under seminatural con…

Axial skeleton of Cebupithecia sarmientoi (Pitheciinae, Platyrrhini) from the middle miocene of La Venta, Colombia
The axial skeleton of Cebupithecia sarmientoi is described and analyzed for its functional and phylogenetic implications. The vertebrae of the holotype of C. sarmientoi (UCMP 38762) most closely resemble those of the extant pitheciine genus Pithecia and display features associated with adaptations for clinging and leaping as in that genus. Cebupithecia has a relatively long non‐prehensile tail, which is most similar in absolute dimensions and pro…
Kinematics of the cercopithecine foot on arboreal and terrestrial substrates with implications for the interpretation of hominid terrestrial adaptations
The stereotyped characterizations of quadrupedal foot postures were tested by examining the kinematics of the cercopithecine foot on arboreal and terrestrial supports. Strictly arboreal species were compared with semi‐terrestrial species for Cercopithecus , Cercocebus , Lophocebus , and Papio , in semi‐natural or experimental settings. Results indicate that the kinematics of the cercopithecine arboreal quadruped differ in degree from stereotypica…
Partial humeri of two Miocene Colombian primates
Distal portions of humeri from two Miocene Colombian primates were recovered during field work in 1986. The larger IGM 183420 is very similar in size and morphology to the humerus included in the type specimen of Cebupithecia sarmientoi , recovered from La Venta in 1945 (Stirton and Savage: Serv. Geol. Nac. Bogata 7 :345–356, 1951) and is assigned to this taxon. IGM 183420 presents a number of features of the humerus associated with clinging post…
New fossil platyrrhine tali from the early miocene of Argentina
Five platyrrhine tali have been recovered from early Miocene localities in the Pinturas Formation of Santa Cruz Province, Argentina. These new fossil tali show overall greater similarities to the slightly older Gaiman talus attributed to Dolichocebus gaimanensis than to tali of the younger primate taxa from La Venta, Colombia. The smallest and oldest talus from the Pinturas Formation displays features similar to the extant atelines and Pithecia ,…
Locomotor behavior and skeletal morphology of two sympatric pitheciine monkeys, Pithecia pithecia and Chiropotes satanas
Field observations of two sympatric pitheciine species reveal that the positional repertoire of the white‐faced saki, Pithecia pithecia , is dominated by leaping behaviors, whereas the bearded saki, Chiropotes satanas , is predominantly quadrupedal. Examination and comparison of the postcranial skeletal morphologies and limb proportions of these species display numerous features associated with their respective locomotor behaviors. These observat…
