Hip structure and locomotion in ambulatory and cursorial carnivores reinvestigated [abstract]
(2010)
Understanding how the femoral head articulates with the acetabulum of the pelvis should allow one to infer the pattern of hip mobility in living and fossil species. In 1977, Jenkins and Camazine analyzed cineradiographic ...
Estimating radial curvature in fragmentary hominin fossils : a comparative study in apes and humans [abstract]
(2010)
Forearm bone curvature has been invoked in interpretation of fossil hominin behavior. Apes have curved radii, reflecting hypertrophied forearm musculature needed for below-branch arboreal locomotion and increased leverage ...
3D analysis of primate hindlimb joints : reconstructing positional abilities in extinct primates [abstract]
(2010)
This study uses articulated 3D polygonal models of the pelvis and femur to simulate range of abduction during loading, and evaluates effects of different aspects of morphology on femoral postures. Continuous laser scan ...
Second rib curvature in apes and humans and implications for the evolution of thoracic shape in early hominins [abstract]
(2010)
Thoracic form in humans is often described as "barrel-shaped" with a broad upper rib cage, a condition different from great apes, who have a "cone-shaped" thorax and narrower upper rib cage. The earliest Australopithecus ...
