First partial skeleton of a 1.34-million-year-old Paranthropus boisei from Bed II, Olduvai Gorge, Tanzania. [PDF]

PLoS ONE, 2013
Recent excavations in Level 4 at BK (Bed II, Olduvai Gorge, Tanzania) have yielded nine hominin teeth, a distal humerus fragment, a proximal radius with much of its shaft, a femur shaft, and a tibia shaft fragment (cataloged collectively as OH 80). Those

Baboon feeding ecology informs the dietary niche of Paranthropus boisei. [PDF]

PLoS ONE, 2014
Hominins are generally considered eclectic omnivores like baboons, but recent isotope studies call into question the generalist status of some hominins. Paranthropus boisei and Australopithecus bahrelghazali derived 75%-80% of their tissues' δ(13)C from ...

Dental microwear and diet of the Plio-Pleistocene hominin Paranthropus boisei.

PLoS ONE, 2008
The Plio-Pleistocene hominin Paranthropus boisei had enormous, flat, thickly enameled cheek teeth, a robust cranium and mandible, and inferred massive, powerful chewing muscles. This specialized morphology, which earned P. boisei the nickname "Nutcracker

Dietary proclivities of Paranthropus robustus from Swartkrans, South Africa [PDF]

Anthropological Review, 2015
Pleistocene Paranthropus robustus fossils from Swartkrans have yielded stable isotope values suggesting some foraging on C4 plants possibly including underground storage organs. Dental microwear texture analysis on P.

Environmental Context of Hominin Foot Evolution. [PDF]

Am J Biol Anthropol
ABSTRACT Objectives This study investigates the environmental contexts that influenced the evolution of hominin foot morphology, focusing on when, where, and under what conditions key synapomorphies evolved. We test whether shifts in ecological conditions are associated with changes in locomotor function.

Clades, Grades, and the Genus Problem: A Case for Revising Hominin Taxonomy. [PDF]

Am J Biol Anthropol
ABSTRACT Taxonomic practice in evolutionary biology increasingly prioritizes the recognition of monophyletic groups (clades), yet paleoanthropology still applies this principle inconsistently. Here, I outline these inconsistencies and broader challenges in hominin taxonomy and propose a potential solution.

Dietary Adaptation in Paranthropus robustus Postcanine Teeth. [PDF]

Am J Biol Anthropol
Upper premolar enamel thickness in Paranthropus robustus increased significantly over time, especially in the occlusal region. ABSTRACT Objectives Recent studies of Paranthropus robustus crania identified temporal trends in features associated with increased bite force production, coinciding with environmental shifts toward more arid conditions.

Unfused transverse foramen of the atlas vertebra in the Neandertal lineage fossils. [PDF]

Anat Rec (Hoboken)
Abstract In anatomically modern humans, the atlas can display an unfused transverse foramen (UTF) but currently the presence of UTF in the Neandertal lineage is uncertain due to a scarcity of prevalence studies and no exhaustive record of its presence throughout the entire hominin fossil record.

Comparative Morphometric Analysis of the Pelvis of LB 1 (Homo floresiensis). [PDF]

Am J Biol Anthropol
ABSTRACT Objectives Although there has been copious research on the postcranial functional morphology of Homo floresiensis, there has been relatively little study of its pelvis and its implications for interpretations of H. floresiensis locomotion. Here we present the first comparative morphometric analysis of the pelvis of LB 1, the holotype of H ...

Evaluating the Evolvability of Paranthropus Cranial Morphology in Relation to Feeding Biomechanics. [PDF]

Am J Biol Anthropol
OBJECTIVE: Although disagreement persists as to the precise nature of the diet of Paranthropus, there is a consensus that the food resources consumed by Paranthropus were in some way mechanically challenging to process (i.e., by being "hard" and/or ...
