Orensic Anthropology osteobiography Assignment

Instructions for forensic anthropology osteobiography assignment:

Background Information:
During the recent renovations at Macewan university, workers discovered a large plastic box containing what appear to be human skeletal remains. Edmonton police services area treating the remains as Suspicious”, but they do not have a human osteologist on staff. As a result, they have brought the skeletal remains to you, Edmontons preeminent team of forensic anthropologist, for analysis.

Objectives: To assit Edmonton polices services in their investigation of suspicious skeletal remains. In particular, your task is to determine:
1. Are the remains human (all of the remains? some of the remains? none of the remains?)
2. Which bones are present and which bones are absent?
3. What is the estimated sex, age and stature of the individual(s)?
4. Are there any pathological lesions or anatomical anomalies that might help identify the individual(s)?
5. Are there any indicators of behaviour that might help identify the individual(s)?

Analysis and Written Report
A forensic anthropologist report is designed to be read by law enforcement offices and other involved in the legal process. Since theses people are not experts in human osteology or anthropology, the report should be simple, brief and concise. The goal in the report is to present, fairly and objectively, all of the data you collected, all the analysis that was conducted, and all of the conclusions.

Please follow this format:

1. Introduction: In this section, briefly introduce the background to the case (see scenario presented above), who you are writing the report form the file number, the data on which you did you work, where the work was completed, the names of your assistant and context (why were you contacted?)
2. Methods: In this section, briefly describe all of the methods you used with proper citations. Be sure to describe the methods in sufficient detail to say that you estimated age by Looking at the teeth”. What about the teeth? Their colour? Wear patterns? Or did you compare the individuals dental eruption pattern with established standards developed by ubelaker (1979).
3. Description of remains: Give a brief overview of the skeletal remains, including which skeletal elements (ex. bones and teeth) were present and what condition they were (broken? poorly preserved? well preserved?) A table in which you list the skeletal inventory of each individual would be very helpful.
4. Minimum number of individuals: In this section, clearly and explicitly tell us how you determined the minimum number of individuals present, and which bones are associated with each individual. Provide the inventory.
5. Osteobiography: Start with individual 1 and discuss each of the following. Then move to individual 2, etc.
i) Sex: State your conclusion and justify how you arrived at this estimation. Remember, responsible osteologists recognize 5 possible sexes.
ii) Age: State your conclusion and justify how you arrived at this estimation. If you use an age range different from the standard ranges (because you can narrow if down using different lines of evidence, for example), make sure you clearly define the age range you are using and your reasons.
iii) Stature: Report the results. A table or chart might be appropriate here, especially if you use multiple bones.
iv) Additional Observations: In this section include any other observations you see regarding trauma, pathological lesions, MSMs, etc.
6. Conclusions: Summarize quickly your results, making sure to answer all of the questions posed (even if the answer is Could not be determined”. This is also the section to discuss any problems you encountered in using materials and methods.
