New fossil crinoids reveal tectonically driven marine passive dispersal

This dataset consists of original data from the following manuscript: Hsu, C.-H., Chung, Y.-C., and Lin, C.-H. New fossil crinoids reveal tectonically driven marine passive dispersal. The dataset comprises the R script used for analyses of latitudinal dispersal (Hsu_et_al_crinoid_rscript_pnas.R), photographs of all examined specimens (Specimen_images.tif), and the geological map of the sampling localities (Geological_map.tif).
