The supports on which an arboreal mammal sits, lies, or moves are the branches and trunks
of trees, and these differ from the surface of the earth in four important ways; they are (1) …

The characteristics of" climbing" in the sense of locomotion or posture on three dimensional

Investigations of the posture and locomotion of fossil Primates are based upon comparative
studies of those features of the post'cranial skeleton which can be shown, by an examination …

It is now well recognized that terrestrial mammals can maintain equivalent bone stresses
despite dramatic differences in body size through the adoption of extended limb positions …

For over a century it has been known that primates have highly mobile grasping forelimbs
with the supportive functions shifted more strongly to the hindlimbs, unlike most mammals …

The rationale for most field studies of the positional behavior of arboreal primates has been
the need to document natural behaviors quantitatively in order to infer the functional …

Apart from marsupials and edentates, there is no order of mammals, living or fossil, which
