How forensic anthropologists identify human remains

Summary

Forensic anthropologists play a crucial role in solving the mysteries surrounding unidentified human remains by meticulously analyzing bones to provide a name and story for the deceased. Through a detailed examination of the skeleton, specialists assess factors like age, sex, and ancestry, while recording any trauma or unique features. This involves inspecting bones for animal gnawing or other trauma, analyzing pelvis shapes for gender clues, studying ribs and growth plates for age determination, and evaluating skull features and dental records for ancestry and identity verification. This process ultimately aids in restoring dignity to the deceased by reuniting remains with their loved ones and, if applicable, seeking justice for violent deaths.

Chapters

• 00:00 - 00:30: Introduction and Objectives of Forensic Anthropology Forensic anthropology is akin to speaking for the deceased, especially in cases of violent death, to seek justice and identification, ultimately reuniting them with loved ones. Analysts meticulously examine each bone for trauma and signs such as marks from carnivores.
• 00:30 - 02:00: Methods for Determining Sex through Skeletal Analysis The chapter focuses on methods to determine sex through skeletal analysis, primarily examining the shape of the pelvis. A wider pelvic shape is indicative of females, while a narrower one suggests males. The chapter also considers documenting types of gnawing on bones as part of the skeletal analysis process.
• 02:00 - 02:30: Determining Age through Skeletal Examination In this chapter, the process of determining age through skeletal examination is discussed. Key aspects include the examination of the ribs and the medial end of the clavicle, specifically the epiphysis or growth plate, to determine if an individual is under or over 30 years of age. This serves as a critical dividing point in age estimation. Additionally, the analysis of the cranium and forehead is mentioned as useful in the determination of age.
• 02:30 - 03:00: Assessment of Ancestry using Skull Features The chapter focuses on assessing ancestry by examining various skull features. It highlights the differences in skull characteristics between males and females, noting that females tend to have flatter foreheads while males have more receding foreheads with a pronounced brow ridge. The chapter also discusses the mastoid processes, which are areas of muscle attachment that are typically larger in males. Furthermore, the chapter examines the chin as well as facial features and other skull areas to aid in the evaluation of ancestry.
• 03:00 - 04:00: Role of Dental Examination in Identification In this chapter, the focus is on the role of dental examinations in identifying individuals based on their sex, ancestry, and age. The analysis of teeth, including the presence and development of third molars, is highlighted as a significant indicator of age. Additionally, dental work present in the individual's mouth can also aid in identification.
• 04:00 - 05:00: Age-related Changes in Pubic Symphysis and Ribs This chapter discusses the age-related changes observed in the pubic symphysis and ribs. It explains how the pubic symphysis, which initially has a wavy texture, smoothens out as a person ages and later degrades. Similarly, the chapter suggests that ribs follow a comparable process of change throughout an individual's life.
• 05:00 - 06:00: Use of Unique Skeletal Features for Identification The chapter discusses the use of unique skeletal features in identifying individuals. It starts by describing the differences between male and female skeletal structures. The description includes the progression of bone surface from a 'billowy' undulating texture to a hollowed appearance, and eventually to a 'Crab Claw' morphology as a person ages. Additionally, the chapter emphasizes the importance of examining all available information, such as unique skeletal traits or evidence of anti-mortem trauma, to identify the person under study.

• 00:00 - 00:30 we kind of like to say that we we like to speak for for the deceased um so you know we can get Justice for them if they were a victim of a violent death um and you know the most important thing is being able to identify them give them their name back and return them to their loved ones when we do an analysis every bone we look over every surface make sure there's no trauma we'll also have you know oftentimes carnivore or other
• 00:30 - 01:00 types of gnawing on the bones and will want to document that as well we'll look kind of at the shape of the pelvis if it's like really wide in this area that is more indicative of female versus uh like a narrow opening is more indicative of male and then kind of this you know this Inlet again male male on the left female on the right it's just
• 01:00 - 01:30 the architecture that's related to having kids we will also look at the ribs for aging we can look at the medial end of the clavicle and that's really helps us determine if they are you know under 30 or over 30 so it's kind of like a dividing point because that's when that epiphysis or growth plate fuses and then the cranium is great but we'll look at things like the forehead
• 01:30 - 02:00 females tend to have kind of flat foreheads males have kind of more receding and more of kind of a brow Ridge in this area we'll look at the mastoid processes again that's a muscle attachment so it'll be bigger for males generally we'll look at the chin and then we'll also look at features of the face in particular and other areas of the skull to help us assess ancestry
• 02:00 - 02:30 and then of course we've got the teeth that we can look at to help us for sex and ancestry and age like for instance this individual has their third molars still in the Crypt and so as we all know third molars are not they can come out at different times or they can get impacted but that can be an indicator of of age as well and then if the person has dental work that can help us
• 02:30 - 03:00 identify the person the pubic symphysis so again this area right here how it um kind of progresses from like kind of this surface that has a lot of waves and then as you get older it starts to kind of break down so it builds up builds up gets nice and kind of flat and then it starts to to degrade after that and then the ribs also go through kind of that system of
• 03:00 - 03:30 male and female so it starts out kind of we like to call it billowy surface kind of that undulating surface and then it kind of Hollows out and then you start to get kind of this more Crab Claw morphology the older you get so we'll just kind of look at all the information that were provided to try and figure out who this who this person is if there's any unique features you know even if it's anti-mortem trauma you know if this had
• 03:30 - 04:00 a nice big like callus or if it was you know maybe not aligned correctly and it healed you know kind of weirdly we would say well this person broke their you know humorous at some point and it looks like you know maybe it didn't get set well it might have been a visible kind of deformity that could help identify the individual so all of these things you know it's all kind of part of the the puzzle and part of the mystery trying to figure out who this person is
