View of a human skull with roots in orbits and nasal cavities. The roots are useful in taphonomic studies since they are indicators of the depositional context in which the skull was buried. The skull was unearthed in a cementery in northern Patagonia, Argentina, for scientific purposes. Photo by Romina Clara

Right frontal view of a human skull whose orbit and nasal cavity have numerous roots. The roots are useful in taphonomic studies since they are indicators of the depositional context in which the skull was buried. The skull was unearthed in a contemporary cementery placed in northern Patagonia, Argentina, for scientific purposes. Photo by Romina Clara
