Mayapan Community Dataset
The data files below provide counts for lithic flakes with no evidence of use or retouch described by size, material, and collection context from excavations in 2001-2004.
[Comma delimited UTF-8 format]
[Excel format]
Each line in the CSV file represents all lithic flakes of a certain material and size within a given context. There are 7,868 lines, each with 15 variables separated by commas. The variables are listed in the following order:
| 1 | Associated project name and collection type:
|
| 2 | Structure number |
| 3 | Surface collection number (for systematic 3m dog leash collections) |
| 4 | Secondary collection number (if more than one collection was made in this locality) |
| 5 | Milpa number |
| 6 | Pozo (test pit) number |
| 7 | Level |
| 8 | Lot number; unique ID to features or levels in excavation units |
| 9 | Unit (2x2 meter grid for horizontal excavations) |
| 10 | Stratigraphic Layer (cultural or natural layer) |
| 11 | Nested screen size (in inches) |
| 12 | Cortex (percent of dorsal surface covered) |
| 13 | Number of flakes |
| 14 | Material (note: 'chal' is chalcedony) |
| 15 | Color |
The first line of the CSV file, for example, looks like this:
PEMY Random sample (RS) test pit,Q-303,,,1,RS1,4,1020,,,0.25,0,1,Chal,gray/brown
This means that the flake is associated with the PEMY project and is from a randomly sampled test pit at structure Q-303. There are no surface collection numbers or secondary collection numbers since this flake comes from a randomly sampled test pit. The flake was excavated from milpa number 1, test pit number RS1, level 4, lot 1020. There are no unit numbers or stratigraphic layers associated with this record. The nested screen used has 0.25 inch mesh and the flake has 0% cortex on its dorsal surface. Only one flake was taken from this locality, which is chalcedony and gray/brown in color.
