1

Oldowan industry

the earliest stone tool industry, characterized by pebble and chopping tools made and used by early hominins

2

Lower Paleolithic

the period associated with the Oldowan and Acheulian stone tool industries

3

quarrying sites

sites from which hominins obtained raw materials to make stone tools

4

experimental archaeology

a field of archaeology that uses a number of different methods to test hypotheses about how artifacts and structures may have been made and used

5

occlusal relief

the ratio of the three-dimensional surface area of a tooth to the two-dimensional occlusal surface area

6

dental topographic analysis

a method of analysis that involves using a laser scanner to generate 3D models of teeth and GIS to measure features on the surfaces of those teeth

7

stable isotope analysis

a type of chemical analysis that looks at stable isotopes of certain elements in bones and other tissues of the body; it can tell us something about the diet and residential history of an individual

8

collagen

a type of protein that forms the main organic component of bone

9

apatite

the major inorganic component of bones and teeth

10

12

sagittal keel

a raised area of bone running along the sagittal suture

13

supraorbital torus

a ridge of bone running across the tope of the eyes; also referred to as the browridge

14

occipital torus

a horizontal ridge of bone running across the occipital lobe

15

diaphyses

the shafts of the long bones

16

epiphyses

the caps at the ends of the long bones; bone growth ceases when the epiphyses fuse to the diaphysis

17

Acheulian

a Lower Paleolithic stone tool industry usually associated with Homo erectus

18

bifacial tool

a stone tool that has had flakes removed from opposite sides to produce a cutting edge

19

hand axe

a teardrop-shaped stone tool characteristic of the Acheulian industry

20

21
