Locations of sediment samples collected for DNA analyses, shown on a plan of the Sefunim Cave excavation. Samples are color-coded according to the layer from which they originate, with a cross indicating samples that tested positive for the preservation of ancient mammalian mtDNA. The gray line depicts the outline of the boulder removed from the excavation area in 2017 prior to sampling. The dashed gray line shows the inferred extent of the rock before Ronen removed part of it. The red arrows represent the two main sections shown in Fig. 3. The photographs on the right document the gradual removal of the limestone boulder before its complete removal. The distribution map was generated with ArcGIS Desktop 10.6.1.9270 (https://desktop.arcgis.com); photographs are by A. Kandel.
