Almost 100 million years ago, the Kokorkom Desert stretched across the region now occupied by the provinces of Río Negro and Neuquén in Argentina; it was a vast system of mobile dunes in a hot and arid climate, shaped by the wind. This fossil-rich zone, which is part of La Buitrera, discovered and studied over the last 25 years by Dr. Sebastián Apesteguía and his team, has been the site of numerous significant paleontological finds. This landscape was home to a diverse community of animals adapted to extreme conditions: legged snakes, lizards, sphenodonts, omnivorous crocodiles, and herbivorous dinosaurs such as Jakapil, alongside carnivores such as Buitreraptor and Alnashetri. In this environment emerged Antusuchus rionegrinus, a medium-sized terrestrial crocodile, comparable in size to a modern dog.
