Textural properties and functional morphology of the hip bone cancellous network of Oreopithecus bambolii, a 9- to 7-million-year-old Late Miocene hominoid from Italy, provide insights into the postural and locomotor behavior of this fossil ape. Digital image processing of calibrated hip bone radiographs reveals the occurrence of trabecular features, which, in humans and fossil hominids, are related to vertical support of the body weight, i.e., to bipedality.

Although specific hand use is still unresolved in Oreopithecus, the results suggest enhanced manipulative skills (unrelated to stone tool-making) in this taxon relative to other (extant or fossil) hominoids.

A review of trabecular bone functional adaptation: what have we learned from trabecular analyses in extant hominoids and what can we apply to fossils?

This review addresses the current understanding of trabecular bone functional adaptation, how it has been applied to hominoids, as well as other primates and, ultimately, how this can be used to better interpret fossil hominoid and hominin morphology.

This study quantified trabecular orientation above the acetabulum to test the hypothesis that hominoid biomechanical behavior is recorded in the cancellous bone to discuss the variation in the FFT spectrum between species in the light of distinctive biomechanicals features.

Femoral head trabecular bone structure in two omomyid primates.

Despite the overall similarities in the external postcranial anatomy of Omomys and Shoshonius, the results of this study indicate potentially important differences in the magnitude of the external loads at the hip joint, suggesting that these animals engaged in divergent locomotor behaviors.

It is illustrated with a first example from a sample of human, Pan, Papio and Neanderthal patellae that the development of a “whole-bone” endostructural analysis has the potential to provide relevant functional information for reconstructing the knee loading environment in fossil taxa, combined, whenever necessary, with a subsampling approach.

The Functional and Allometric Implications of Hipbone Trabecular Microarchitecture in a Sample of Eutherian and Metatherian Mammals

A weak functional signal was found detected in differences in bone volume fraction and the degree of anisotropy across certain pre-assigned locomotor categories, while confirming previously recognized allometric scaling trends reported for other mammalian samples based on the femur.
