Mayapan Community Dataset
The data files below provide lithic tool counts broken down by size, material, function, and collection context from excavation in 2008.
[Comma delimited UTF-8 format]
[Excel format]
Each line in the CSV file represents one tool type per collection unit. There are 79 lines, each with 16 variables separated by commas. The variables are listed in the following order:
| 1 | Structure |
| 2 | Cuadro |
| 3 | Lote |
| 4 | Nivel |
| 5 | Capa |
| 6 | Tool type |
| 7 | Portion of tool recovered |
| 8 | Raw material |
| 9 | Raw material color |
| 10 | Cortex |
| 11 | Length (cm)
Note: NA indicates that the measurement was on a fragment and does not reflect the artifact's original dimension |
| 12 | Width (cm)
Note: NA indicates that the measurement was on a fragment and does not reflect the artifact's original dimension |
| 13 | Thickness (cm)
Note: NA indicates that the measurement was on a fragment and does not reflect the artifact's original dimension |
| 14 | Patination, where Y = patination and N or blank = no patination |
| 15 | Fire damage, where Y = visible fire damage and N or blank = no visible fire damage |
| 16 | Notes |
The first line of the CSV file, for example, looks like this:
H-11,6-G,5056,1,I,Biface,Distal,CHL,Grayish brown,0,4.1,4.1,1.3,Y,N,"Piano-convex cross section, broken and retouched proximal end, bifacially flaked edges"
This means that this tool was excavated from structure H-11, cuadro 6-G, lote 5056, nivel 1, and capa I. It is biface with only the distal portion recovered. It is comprised of a chalcedony that is grayish brown in color with no cortex present. The tool has a length of 4.1 cm (which was measured from a fragment and is not the original length of the tool), a width of 4.1 cm, and a thickness of 1.3 cm. It has patination. No fire damage is described and it is noted that the tool features a "Piano-convex cross section, broken and retouched proximal end, bifacially flaked edges."
