Functional Morphology Of The Platyrrhine Humerus And Talus: Implications For Inferring Locomotor Behavior In Extinct Primates, Liam Michael Zachary

Graduate Theses and Dissertations

Platyrrhines are a diverse radiation of primates that exhibit a range of locomotor adaptations. The relationships between extant primate locomotor behavior and variation in postcranial morphology are often used to make functional interpretations of skeletal anatomy in extinct primates. However, a comparative baseline of form-function relationships in the extant platyrrhine postcranium is lacking compared to other primates, which limits understanding of platyrrhine locomotor evolution. The humerus and talus are two of the best represented skeletal elements in the platyrrhine fossil record and are informative of locomotor behavior. Therefore, quantification of morphological variation in extant platyrrhine tali and humeri can provide …

Age And Inclusivity In Umm An-Nar Communal Tombs From Southeastern Arabia, Lesley A. Gregoricka, Jaime M. Ullinger, Christian Berends, Alyssa Bolster, Brittany Clark, Hannah Jeanlouis, Urvi Kaul, Rachael Orkin

Year 2: AABA 2022 – Denver, CO

Umm an-Nar (2700-2000 BCE) tombs in the United Arab Emirates contained the commingled remains of hundreds of individuals interred across multiple generations. Archaeologists commonly reference tomb demographics as being inclusive of all ages, but this assumption is based on a handful of studies that rarely distinguish age categories beyond “subadult” or “adult.” An undergraduate research training program sought to examine age distributions – and thus inclusivity in tomb membership – in greater detail, with a particular focus on fetal and older adult age categories.

A combination of traditional and novel aging techniques were applied to bones from tombs Unar 1 …

A Transition From Tradition: Employing Ta3 And Traditional Age & Sex Estimation Methods To Study Paleodemography In Umm An-Nar Arabia, Alyssa Bolster, Hannah Jeanlouis, Lesley A. Gregoricka, Jaime M. Ullinger

Year 2: AABA 2022 – Denver, CO

Background: Transition Analysis 3 (TA3) has enormous potential for the study of commingled skeletal material. Previous demographic analyses on commingled remains from Umm an-Nar (2700-2000 BCE) tombs Unar 1 and Unar 2 at the site of Shimal (Ras al-Khaimah, UAE) placed the majority of individuals in a generalized “adult” category using dental eruption. We hypothesized that we would identify more older adults (50+) in both tombs using TA3, and that more would be found in Unar 2, prior to the intensification of agriculture and regional aridification.

Methods: Commingled and fragmentary skeletal fragments (pubic symphyses (n=51), humeri (n=85), femora (n=194)) were …

An Examination Of Sex Distributions In Umm An-Nar Tombs From Bronze Age Arabia Using The Distal Humerus, Charles Downey, Silvio Ernesto Mirabal Torres, Lesley A. Gregoricka, Jaime M. Ullinger

Year 1: AAPA 2021 – virtual

Background: Umm an-Nar (2700-2000 BCE) communal tombs from southeastern Arabia contain human skeletal remains characterized by extensive commingling and variable degrees of burning. Because of this, few bioarchaeological studies have been conducted examining the proportions of males to females in these monumental tombs. We hypothesized that increased social stratification in the late Umm an-Nar period would lead to a higher number of males interred in Umm an-Nar tombs over time.

Methods: To estimate sex, we measured four features of the distal humeri from tombs Unar 1 (2400-2200 BCE) and Unar 2 (2300-2100 BCE). Heat-induced changes to bone from cremation were …

Mni And Sex Estimation In Two Umm An-Nar Tombs From The Uae, Jaime M. Ullinger, Lesley A. Gregoricka, Chaylee Arellano, Quentin Burke, Victoria Calvin, Charlie Downey, Rachel Heil, Alyssa Mcgrath, Silvio Ernesto Mirabal Torres, Jeremy Simmons

Year 1: AAPA 2021 – virtual

Commingled tombs are often overlooked in bioarchaeological studies because of the difficult nature of analysis, despite their prevalence across the ancient world. Tombs Unar 1 (U1) and Unar 2 (U2), located in the United Arab Emirates, date to the Umm an-Nar period (2700-2000 BCE), when people witnessed shifts in mortuary practices likely reflective of broader changes in subsistence and social organization. A collaborative project that trains undergraduates in anthropological research has examined tomb membership for U1 and U2 by estimating MNI and sex. Despite early descriptions of U1 and U2 holding similar numbers of individuals, this project found that MNI …

Cremation And Secondary Burial Practices Among Umm An-Nar Communities In Bronze Age Arabia, Antonia Carter

Anthropology Undergraduate Senior Theses

Understanding the ways in which the living processed their dead is a vital component to the field of bioarchaeology, so the purpose of this research is to provide insight into funerary practices for a Bronze Age community in southeastern Arabia and demonstrate a possible difference in mortuary treatment between one generation and the next. By using the Munsell color chart to assign color codes to five areas of testable distal humeri from two Bronze Age Umm an-Nar tombs (Unar 1 and Unar 2) located in the Shimal necropolis in the United Arab Emirates, a statistically significant difference between the articular …

A Qualitative Analysis For Sex Determination In Humans Utilizing Posterior And Medial Aspects Of The Distal Humerus, Veronica L. Wanek

Dissertations and Theses

Visual and metric analysis both provide accepted methods for sex determination in humans. Visual ascertainment uses differing morphological traits in males and females to establish sex. Researchers have continually sought accurate methods of sexing long bones when skulls or pelves are absent or fragmented. These long bone elements may not have sexually distinct characteristics, but tend to survive in the field quite well.

Metric analysis depends on size dimorphism between males and females to correctly assign sex. Metric methods fail where the sexes overlap or when skeletal elements cannot be assigned to their correct biological population. Under these conditions, visual …
