A calvarial osteolytic lesion of probable vascular origin in a Maya juvenile from the Classic Period ( 250-900 CE).

Objective: This case study evaluates a focal osteolytic lesion in the right sulcus sinus transversi of an isolated os occipitale.

Materials: The os occipitale is from a juvenile from the Cueva de Sangre at the Classic Period (250-900 CE) site of Dos Pilas, Guatemala METHODS: The lesion was examined macroscopically, microscopically, and radiographically.

Results: The oval lesion has a well-circumscribed margin, endocranial origin, and involves cortical destruction of the inner and outer tables.

Changes in limb bone diaphyseal structure in chimpanzees during development.

Objectives: This study tests if femoral and humeral cross-sectional geometry (CSG) and cross-sectional properties (CSPs) in an ontogenetic series of wild-caught chimpanzees (Pan troglodytes ssp.) reflect locomotor behavior during development. The goal is to clarify the relationship between limb bone structure and locomotor behavior during ontogeny in Pan.

Growth of the pectoral girdle in a sample of juveniles from the kellis 2 cemetery, Dakhleh Oasis, Egypt.

Objectives: This study investigates growth patterns in the scapula and clavicle in a cross-sectional juvenile skeletal sample ranging from 20 weeks gestation to 8.5 years of age from the Kellis 2 cemetery, Dakhleh Oasis, Egypt. The primary goal is to quantify growth patterns and growth velocities in the scapula and clavicle to better understand the development of the pectoral girdle.

Ontogenetic changes in intralimb proportions in a Romano-Christian period sample from the Dakhleh Oasis, Egypt.

Objectives: The purpose of this study is to document the appearance of adult patterns in intralimb indices during ontogeny in a skeletal sample from the Kellis 2 cemetery, Dakhleh Oasis, Egypt. In addition, this study explores evolvability in intralimb indices to understand relative differences in sensitivity to ecogeographic variables.

Methods: Brachial and crural indices were compared across age cohorts with Welch's ANOVA tests and post-hoc Dunnett-Tukey-Kramer (DTK) pairwise multiple comparison tests.

An exploration of adult body shape and limb proportions at Kellis 2, Dakhleh Oasis, Egypt.

Several studies have shown that the human body generally conforms to the ecogeographical expectations of Bergmann's and Allen's rules; however, recent evidence suggests that these expectations may not hold completely for some populations. Egypt is located at the crossroads of Sub-Saharan Africa, Southern Europe, and the Near East, and gene flow among groups in these regions may confound ecogeographical patterning. In this study, we test the fit of the adult physique of a large sample (N = 163) of females and males from the Kellis 2 cemetery (Dakhleh Oasis, Egypt) against ecogeographical predictions.
