Perforated Tritia Shells from El Mnasra Cave Archaeological Site

272 perforated shells of Tritia cf. gibbosula from US 8 of El Mnasra cave, compared with specimens from Djerba and Taforalt. The dataset categorizes shell perforation types and conditions for archaeological analysis. It was authored by Emilie Campmas and shared under a CC BY 4.0 license.

Use Cases

• Classify shell perforation types (e.g., left, central, right, large, open) across the 272 specimens for taphonomic studies.
• Compare perforation patterns in the El Mnasra cave collection with biocenosis and thanatocoenosis data from Djerba and Taforalt.
• Analyze the frequency of shell conditions like 'broken on the proximal portion' or 'without the dorsal portion' within the assemblage.

Strengths

• Dataset provides a focused sample of 272 shells for detailed morphological comparison.
• Includes clear categorical labels for perforation types and shell conditions based on archaeological infography.
• Shared under a permissive CC BY 4.0 license for reuse and modification.

Limitations

• Very small dataset at 5.5 KB, limiting statistical power for broad inferences.
• Data scope is narrow, focused on a single species from specific archaeological units and comparative sites.
• Column structure and additional variables are unknown from the provided description.
