Data from Spondylus as a Driver of Interregional Exchange (Carter 2022)

This is data published in the attached chapter as appendix 11.1. It is in CSV and GeoJSON format. These are published records of Spondylus crassisquama (formerly S. princeps) and Spondylus limbatus (formerly S. calcifer) with geographic location. Note that the locations are general (often, for example, sources would state near X island, so I put the location near that island without knowing any additional details). These are for broad scale examination only.
