Fig. 1: Map showing the sampling distributions of both modern and ancient samples of C. auratus.

Red diamonds indicate sites where ancient mitochondrial genomes were obtained, numbers behind site names indicate number of successfully sequenced mitochondrial genomes. See Fig. S1 for a map showing all ancient sampling sites and Table S1 for location information. The table on the top right shows the estimated age of the ancient sampling sites, and samples regions to which they are allocated.
