– GPR profiles of pig cadavers simulating human burials over a six-month timeframe. Three simulated pig burials were created at the Australian Facility for Taphonomic Experimental Research (AFTER) and surveyed with GPR pre-burial, and then one-day, one-month, and six months post burial (in this order from top to bottom). The grave locations are shown by the green rectangles, with the left grave being a single burial (one pig) at a depth of 0.5 m, the middle grave being a mass grave (three pigs) at a depth of 1 m, and the right grave being a single burial (one pig) at a depth of 2 m. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
