Enamel Prism Angle Variation and Hard-Object Feeding in Cercopithecoids With Known Diets. [PDF]

Am J Biol Anthropol
Left: Cercocebus atys specimen 16–9 third molar showing Phase II enamel prism angle (angle between prism path and wear facet) and wear angle (angle between wear facet and enamel dentin junction (EDJ)). Scatterplot of prism vs. wear angles for the Phase II wear facet. Note the higher angles for Cercocebus.

Jaw-Muscle Structure and Function in Primates: Insights Into Muscle Performance and Feeding-System Behaviors. [PDF]

Evol Anthropol
ABSTRACT The jaw‐adductor muscles drive the movements and forces associated with primate feeding behaviors such as biting and chewing as well as social signaling behaviors such as wide‐mouth canine display. The past several decades have seen a rise in research aimed at the anatomy and physiology of primate chewing muscles to better understand the ...

Enamel proteins reveal biological sex and genetic variability in southern African <i>Paranthropus</i>. [PDF]

Science
Paranthropus robustus is a morphologically well-documented Early Pleistocene hominin species from southern Africa with no genetic evidence reported so far.

Taxonomic and sex differences in sagittal cresting among gracile and robust capuchin monkeys. [PDF]

J Anat
In this study, I show that there are interspecific differences in the frequency and pattern of sagittal cresting among six capuchin species. Four of the six species show sagittal cresting, with Cebus capucinus showing a different sagittal cresting pattern to that observed in three robust capuchin species. All four crested species show sexual dimorphism

Brief Communication: An Incipient Coronal Caries Lesion on a Neandertal Molar Tooth From El Sidrón Cave (Northern Spain). [PDF]

Am J Biol Anthropol
ABSTRACT Objectives Here, we present the findings of an incipient caries lesion on a permanent upper left second molar attributed to an adult male Neandertal individual from El Sidrón Cave. This study presents new data regarding the antiquity of human caries lesions, their development, and the possibility of the para‐masticatory behavior component as a

Bipedalism or bipedalisms: The os coxae of StW 573. [PDF]

J Anat
There has been a long debate about the possibility of multiple contemporaneous species of Australopithecus in both eastern and southern Africa, potentially exhibiting different forms of bipedal locomotion. Here, we describe the previously unreported morphology of the os coxae in the 3.67 Ma Australopithecus prometheus StW 573 from Sterkfontein Member 2

Enamel proteins reveal biological sex and genetic variability within southern African Paranthropus

, 2023
The evolutionary relationships among extinct African hominin taxa are highly debated and largely unresolved, due in part to a lack of molecular data. Even within taxa, it is not always clear, based on morphology alone, whether ranges of variation are due

The Meaning of Mangabey Molars (And Premolars). [PDF]

Evol Anthropol
ABSTRACT The postcanine teeth of mangabeys (members of Cercocebus and Lophocebus) have figured prominently in discussions about the relationship between hard‐object feeding and dental form. Grey‐cheeked mangabeys (Lophocebus albigena) and sooty mangabeys (Cercocebus atys) both have thickly enameled posterior teeth.
