  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

  The paleontologist Sebastián Apesteguía standing in front of sauropod dinosaur tracks preserved in rocks of the Upper Cretaceous El Molino Formation, Bolivia, of about 67 Million years. More than 10 thousand dinosaur tracks are visible in Sucre. These trackways were preserved in the Cal Orko fossil bed Bolivia. Photo by Paleoninja
• 
  The bones of the carnivorous dinosaur Meraxes gigas outcrop from rocks of the Cretaceous Huincul Formation (93 million years old), in Neuquén, Argentina. Meraxes is a carcharodontosaurid, one of the largest known theropod dinosaurs. Photo by Paleoninja
