Table 3. Features of the anvil and hammerstone used for the fracture of each bone.
| Element | Anvil | Hammerstone | Breakage type | Breakage zone | NISP |
|---|---|---|---|---|---|
| Skull | Angular anvil of limestone with a flat surface | Quartzite pebble | Support on the flat surface, and the floor. Percussion of the bone against the anvil | Supraorbital torus, zygomatics and parietals | 6 |
| Mandible | Angular anvil of limestone with a flat surface | Quartzite pebble | Support on the flat surface | Ramus | 3 |
| Humerus right | Angular anvil of limestone with a flat surface | Quartzite pebble | The bone is supported on one edge of the anvil | Both near epiphyses areas and midshaft | 13 |
| Humerus left | Angular anvil of limestone with a flat surface | Quartzite pebble | Support on the flat surface | Near distal epiphysis and midshaft | 5 |
| Radius right | Angular anvil of limestone with central ridges | Quartzite pebble | The bone is supported on one ridge of the anvil | Midshaft and on radial tuberosity | 9 |
| Radius left | Angular anvil of limestone with central ridges | Quartzite pebble | The bone is supported on one ridge of the anvil | Both near epiphyses areas and midshaft | 9 |
| Ulna right | Angular anvil of limestone with central ridges and anvil with a flat surface | Quartzite pebble | Combination of support on the angles and the flat surface | Near proximal epiphysis and midshaft | 11 |
| Ulna left | Angular anvil of limestone with a flat surface | Quartzite pebble | Support on the flat surface | Near proximal epiphysis and midshaft | 12 |
| Femur right | Angular anvil of limestone with central ridges | Quartzite pebble | The bone is supported on one ridge | Both near epiphyses areas and midshaft | 10 |
| Femur left | Angular anvil of limestone with central ridges | Quartzite pebble and angular limestone | The bone is supported on one edge | Both near epiphyses areas | 8 |
| Tibia right | Angular anvil of limestone with central ridges | Quartzite pebble | The bone is supported on one ridge | Near distal epiphysis and midshaft | 11 |
| Tibia left | Angular anvil of limestone with central ridges | Quartzite pebble | The bone is supported on very sharp edge | Near proximal epiphysis and midshaft | 9 |
| Fibula right | Angular anvil of limestone with central ridges | Quartzite pebble | The bone is supported on one ridge of the anvil | Midshaft | 3 |
| Fibula left | - | Quartzite pebble | Flexion | Midshaft | 7 |
| Metatarsals left | Angular anvil of limestone with a flat surface | Quartzite pebble | Support on the flat surface | Near proximal epiphysis and/or midshaft | 20 |
| Phalanges left | Angular anvil of limestone with a flat surface | Quartzite pebble | Support on the flat surface | Near proximal epiphysis and/or midshaft | 9 |
The table shows the details of the way of broke, the percussion area and the number of remains of more than 2cm obtained.
