Forensic Anthropology 2023 AGE AT DEATH Group members: Skye Sabatasse Each group will receive a bone box containing the left bone casts of a skeleton and most of the thorax. Assume you have a male skeleton. Use your Forensics Manual to score the feature and estimate the age for each element (use the table below). In 1-2 sentences answer the question for each element, using correct terminology. On page 2 you will find 2 sub adult cases to try out using the dental mineralization and development table as well as the epiphyseal fusion table in the manual. Answer the question(s) associated with each case. ADULT AGE: RECORD YOUR ANSWERS IN THE TABLE BELOW: 1. Auricular Surface (Briefly describe why you decided on that particular age range) Decided phase three age range which is less than or equal to 69 years of age. The texture is coarse and the porosity is smaller. The PIIS is very prominent and sticks out. 2. Pubic Symphysis (Briefly describe why you decided on that particular age range) The age range is estimated to be 21- 46 years of age because the pubic surface is granular while the upper and lower extremity are forming. 3. Sacrum fusion (Briefly describe why you decided on that particular age range) Greater than 25 years of age because the alae are all fused together. 4. Sternal Clavicle fusion (Is the epiphysis fused?) Greater than 21 years of age because there is complete fusion with smooth surfaces. METHOD Score or stage Age range Auricular surface 3 Less than or equal to 69 Pubic symphysis 3 Greater than 21, less than 46 Sacrum fusion 4 Greater than 25

Sternal clavicle fusion 4 Greater than 21 AGE RANGE ESTIMATE (the range where the 4 estimates overlap) --------------------------------- -------- 30 - 40 yrs old SUBADULT AGE ESTIMATION Dental mineralization and development CASE 1: The Allegheny County ME’s office was given 2 teeth found in Frick Park over the weekend, and call you in to consult. Immediately you identify the teeth as permanent and identify their developmental stage. Tooth #1: canine (developmental stage: Crc). Tooth #2: lower M1 (developmental stage R3/4) You refer to your dental mineralization and development table above to answer the following: A. What is the approximate age for each tooth? a. Tooth #1: 4.4 b. Tooth #2: 6.1 B. Could the teeth be from the same individual? In 1-2 sentences explain why. No because the age ranges from both are different by two years and from two different individuals. But also yes because each tooth is in a semi permanent stage. CASE 2: It’s a busy day at the ME office. Later the same day, the police deliver a bag of bones that they collected along the North Shore riverbank. Use the dental mineralization and development table at the top of this page and epiphyseal fusion table for males in your Manual to calculate the approximate age of each bone recovered that is listed in the table below.
