How to Use This Calculator
  1. Enter Unit Length, Unit Width, and Level Depth.
  2. Set Total Artifacts, Ceramic Sherds, and Lithic Debitage.
  3. Adjust Faunal Bone as needed.
  4. Review Artifacts per m³ and Site Intensity.
  5. Use Excavated Volume (m³) and Artifacts per m² to inform your decision.

What each input means

Unit Length
Excavation unit length.
Unit Width
Excavation unit width.
Level Depth

Faunal Bone
Number of bone fragments.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Unit Length = 1, Unit Width = 1, Level Depth = 0.1, Total Artifacts = 45 = 7 input(s) provided
  2. Calculate Artifacts per m³
    Artifacts per m³
    450 = 450
  3. Calculate Site Intensity
    Very High Density = Very High Density
  4. Calculate Excavated Volume
    Excavated Volume
    0.1 = 0.1
  5. Calculate Artifacts per m²
    Artifacts per m²
    45 = 45
