Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Trabecular bone ontogeny of the human talus

The Anatomical Record, Volume 309, Issue 7, Page 1837-1874, July 2026.
Abstract Studies of trabecular ontogeny may provide insight into the factors that drive healthy bone development. There is a growing understanding of how the juvenile skeleton responds to these influences; however, gaps in our knowledge remain. This study aims to identify ontogenetic trabecular patterns and regional changes during development within ...

The human bipedalism : epistemology, paleo-anthropology, metaphysics [PDF]

, 2015
La paléoanthropologie utilise la bipédie comme critère d'interprétation des vestiges fossiles permettant d'établir leur appartenance à la lignée humaine. Ainsi, la bipédie devient une caractéristique propre à la lignée humaine et qui en marque l'origine.

The behavioural ecology of hominin locomotion: what can we learn from landscapes of fear and primate terrestriality?

Frontiers in Ecology and Evolution
A defining feature of the hominin clade is bipedality, often parcelled together with terrestriality. However, there is increasing evidence of locomotor diversity, both within the hominin clade and amongst the Miocene apes that came before them.

Why do we transition from walking to running? Energy cost and lower leg muscle activity before and after gait transition under body weight support [PDF]

PeerJ, 2019
Background Minimization of the energetic cost of transport (CoT) has been suggested for the walk-run transition in human locomotion. More recent literature argues that lower leg muscle activities are the potential triggers of the walk-run transition.

Variation in trabecular bone microarchitecture across rhesus macaque (Macaca mulatta) load‐bearing joints

Journal of Anatomy, Volume 249, Issue 1, Page 97-113, July 2026.
Aging of bone density (BV/TV) is regional: Forelimb [left] elements gain bone sporadically (orange) but hind limb elements [right] lose bone globally (blue). Abstract Globally, human population structure is quickly trending older, increasing the prevalence and systemic burden of age‐related skeletal disorders such as osteoporosis.

Does Bipedalism Confer an Advantage to Lizards Sprinting Over Obstacles? [PDF]

, 2017
Terrestrial animals evade predators and capture prey by running over uneven and highly variable terrain. Characterizing the mechanisms to traverse obstacles can clarify crucial aspects of how animals interact with their environment.

The mechanics of the gibbon foot and its potential for elastic energy storage during bipedalism [PDF]

, 2008
The mechanics of the modern human foot and its specialization for habitual bipedalism are well understood. The windlass mechanism gives it the required stability for propulsion generation, and flattening of the arch and stretching of the plantar ...

Investigating Associations Between Developmental Integration and Physiological Stress

American Journal of Biological Anthropology, Volume 190, Issue 2, June 2026.
ABSTRACT Objectives Integration, or patterns of correlation between structural elements, is of interest in diverse fields. Analysis is, however, generally limited to group‐level comparisons. This paper presents a novel combination of methods to quantify developmental integration (i.e., patterns of covariation which arise during growth) so that a ...

“Devolution” of bipedality [PDF]

Proceedings of the National Academy of Sciences, 2008
Ozcelik et al. (1) report mutations in very-low-density lipoprotein receptor (VLDLR) that are associated with quadrupedal gait. They propose a pivotal role for VLDLR in the transition from quadrupedal to bipedal locomotion in man. VLDLR is a key regulator of cerebellar development in vertebrates (2).
