FIGURE 1. Bargiano site. 1. Simplified geological sketch for the study area (redrawn after Monaco et al., 2014). 2. Position of stratigraphic sections reported in Figure 2. Numbers and black dots refer to the position of Ambergrisichnus alleronae cololites (after Monaco et al., 2014). WS=Whale section; S1-S4=additional sections; C27=Section near Cololite #27; C25=Section near Cololite #25; CFT=Cololite Field Trench. 3. Detail of whale bones during June 2016 excavation. 4. Cololite #27. 5. Close-up of Cololite #25.
