Lab 5 ANTH 1022 Lab 5 – Bioarchaeology Response Template Remember to upload this template as a Word document (do not convert to Pages or PDF). An ‘Osteobiography’ represents all the information about someone’s life, identity, and history as told by their skeleton.  In the first part of this lab, you will learn how to estimate an adult’s (~≥18 years) sex from their (a) pelvis and (b) skull using plastic casts set up at stations in the lab.  In the second part of this lab, you will learn how to (a) estimate a nonadult’s (~< 18 years) age-at-death from the state of their dental formation and eruption and (b) how to identify morphological features of the pubic symphysis that permit adult age-estimation from young to old adulthood.  Finally, the third part of this lab session is a thought-exercise that can be completed either in or away from lab (whichever you prefer). You will choose two osteobiographical characteristics, beyond sex and age-at-death, that would be in useful in identifying a recent/modern-day public person (e.g., sports star, actor/actress, politician, musician, chef, journalist, academic, royalty, reality star, etc.) based on their skeletal remains (as uncovered by a future bioarchaeologist 1000 years from now!) PART 1: SEX ESTIMATION Record your observations in the charts below, averaging the observations for each individual in order to estimate their sex. PART 1a: Use this table to record your observations of the pelvis and sex estimations for two individuals (2 marks) (R=right side; L=left side) Skeleton # Ventral arc score (1-5) R L Sub-pubic Angle (1-3) Subpubic Concavity (1-5) R L Greater sciatic notch (1-5) R L Estimated Sex 525E 2 1 1 2 1 1 1 Female 525G 3 4 3 5 4 5 5 Male PART 1b: Use this table to record your observations of the skull and sex estimations for two individuals (2 marks) (R=right side; L=left side) Skeleton # Nuchal crest (1-5) R L Mastoid process (1-5) R L Supra-orbital margin (1-5) R L Glabella (1-5) Mental eminence (1-5) Estimated Sex 523F 1 1 2 1 1 1 1 2 Female 523A 4 4 5 4 4 4 4 5 Male 1

Lab 5 ANTH 1022 PART 2: AGE-AT-DEATH ESTIMATION PART 2a. Using the Ubelaker (1989) dental formation and eruption chart, estimate the age-at- death of one of the two individuals at this station. Always note both the average age and the ‘+/-‘ value. You will need to compare the pattern of tooth formation and eruption in the specimen you’re studying to the diagrams and go with the closest match. Note, teeth coloured white are deciduous (‘baby’) teeth while teeth coloured in grey are the permanent teeth. A tooth is unerupted if it hasn’t breached (come through) the ‘black line’, which represents the border of the jaw. A tooth is in the process of erupting, or is fully erupted, once it breaches the ‘black line’/jaw border. Record the individual’s ID number and estimated age at death here (1 mark) : Skull ID: Skull ii Age-at-death: 10 years old PART 2b. Pick box 1 OR box 2 (you only need to analyze one of these). In each box there are 4 plaster casts (models) of the pubic symphysis that have a letter on them (the letters have nothing to do with the order in which they should be placed). Your task is to examine the morphology of each pubic symphyses in order to assess which comes from the youngest individual, then the second youngest individual, then the second oldest, and finally the oldest individual. Use figures shown in lecture to guide you. Record the box number and order of labelled pubic symphyses from youngest to oldest here (1 mark) : Box #: 2 Youngest: E Second Youngest: M Second Oldest: K Oldest: X PART 3: OSTEOBIOGRAPHY You are a Bioarchaeologist in the year 3022. A large government infrastructure project to build a spaceport has required the movement of an ancient, abandoned cemetery. From ancient documents and grave-markings, you believe that one of the skeletons in the cemetery belongs to a prominent public figure who lived about a thousand years earlier (in the year 2022 or soon before). However, the documents and grave markings are incomplete and are insufficient to identify the individual with certainty. 2
