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.
FIGURE 2. Lithostratigraphic sections through the cetacean excavation site at Bargiano. Lateral distances are not to scale. Acronyms for sections are the same as in Figure 1.2. WFE= whale-fall events (1-3).
FIGURE 3. Plan view across the cetacean excavation surface, at about 357 m above sea level, with the original positions of crab specimens collected around and between the whale bones. Each grid section represents one square meter.
