New hand bones of Hadropithecus stenognathus: Implications for the paleobiology of the Archaeolemuridae
Intrinsic hand proportions of euarchontans and other mammals: Implications for the locomotor behavior of plesiadapiforms
Evolution and development of the primate limb skeleton
The order Primates is composed of many closely related lineages, each having a relatively well established phylogeny supported by both the fossil record and molecular data.1 Primate evolution is characterized by a series of adaptive radiations beginning early in the Cenozoic era. Studies of these radiations have uncovered two major trends. One is that substantial amounts of morphological diversity have been produced over short periods of evolutio…
Primate origins: Evolutionary Change in Digital Ray Patterning and Segmentation
Uniqueness of primate forelimb posture during quadrupedal locomotion
Among the characteristics that are thought to set primate quadrupedal locomotion apart from that of nonprimate mammals are a more protracted limb posture and larger limb angular excursion. However, kinematic aspects of primate or nonprimate quadrupedal locomotion have been documented in only a handful of species, and more widely for the hind than the forelimb. This study presents data on arm (humerus) and forelimb posture during walking for 102 s…

Phalangeal morphology of the Paromomyidae (?Primates, Plesiadapiformes): The evidence for gliding behavior reconsidered
A comparative morphometric analysis of isolated proximal and intermediate phalanges attributed to the paromomyids Ignacius graybullianus and Phenacolemur simonsi was undertaken to test the hypothesis that these fossil phalanges exhibit evidence of a dermopteran-like interdigital patagium. Linear dimensions were collected for the fossil phalanges and a comparative sample of associated proximal and intermediate phalanges representing extant tree sq…
Pattern and process in the evolution of primate nails and claws
Functional and adaptive significance of primate pads and claws: Evidence from New World anthropoids
This study tests predicted morphoclines in fingertip morphology among four small-bodied (<1 kg) New World monkeys (Saimiri sciureus, Leontopithecus rosalia, Callithrix jacchus, and Saguinus oedipus) in order to test previous functional and adaptive explanations for the evolution of flattened nails, expanded apical pads, and grasping extremities within the Order Primates. Small-bodied platyrrhines which frequently forage among small-diameter subst…

EMG of the human flexor pollicis longus muscle: Implications for the Evolution of Hominid Tool Use
Functional osteology of the primate carpus with special reference to strepsirhini
Preuschoft et al. ([1993] in H. Preuschoft and D. Chivers (eds): Hands of Primates. New York: Springer-Verlag, pp. 245-256) used a theoretical biomechanical analysis to generate several predictions relating subordinal differences in primate hand proportions to differences in carpal morphology. This study tests these predictions using quantitative analyses of carpal morphology between extant haplorhine and strepsirhine primates. Results show that …

Locomotor adaptations reflected in the wrist joints of early tertiary primates (adapiformes)
Locomotor adaptations reflected in the wrist joints of early tertiary primates (adapiformes)
The positional behaviors inferred for early Tertiary adapiform primates have been the subject of considerable debate. Adapiform wrist morphology is analyzed here within the context of extant morphoclines in carpal joint shape in order to reconstruct adapiform positional behavior. Extant vertical clingers, slow climbers, and arboreal quadrupeds differ significantly from one another in length of the m flexor carpi ulnaris lever arm, shape of the mi…
Functional morphology of the lemuriform wrist joints and the relationship between wrist morphology and positional behavior in arboreal primates
A comparative study of carpal joint structure and function in six Malagasy lemuriforms was undertaken to test predicted morphoclines in carpal joint morphology between pronograde and orthograde arboreal primates. Patterns of movement at the wrist during locomotion were observed and described for the lemuriform species Lemur fulvus and Propithecus verreauxi. Lemur fulvus, which assumes a pronograde posture during locomotion, extends and pronates t…
