Vocab to know
Vocab to know

  • Skeletal Modification –

    • Any changes made to the skeleton

  • Pre- or antemortem –

    • Modifications made before death

      • Examples: breaking a bone as a kid

  • Perimortem –

    • Modifications made just before, during, or just after death; “around the time of death”

      • Example: stabbing someone & nicking the ribs or vertebrae

  • Postmortem –

    • Modifications made after death

      • Examples: bones that get broken when they are buried or run through a grinder or shredder, etc.. Think back to some of the episodes we watched…


Taphonomy
Taphonomy

  • The study of the processes that operate between the time of death and the time of study (Human Bone Manual)

  • A subdiscipline of paleontology; but also in the realm of archaeology

    • Looks at the contexts of skeletal remains’ resting place

      • How were they buried? Where were they buried? What were they buried with? Body position? Etc…..

Skeletal Modification

  • Modification by Physical Agents

    • Chemistry – the soil the remains are in; weathering; natural decomposition of the body

    • Rocks, Earth, Ice – Bones can be broken or scratched by rockfalls; freeze-thaw cycles

    • Abrasion – particles of grit that “sand” the bones

    • Fire – cremation vs. naturally- occurring fires vs. roasting

  • Modification by Nonhuman, Biological Agents

    • Non-Human Animals

      • Gnawing/chewing on bones; sings of carnivores include: pitting, scoring and puncturing of bone; trampling

    • Plants –

      • Roots can grow through & around bones, leaving evidence on the bone; looks similar to etching

  • Modification by Humans

    • Cannibalism; cremation; cutting, chopping, scraping; percussion (hammering); projectiles (arrowheads, bullets, spearheads, etc…)
