Itapecuru Mirim, Brazil

With a population of just 60,440, Itapecuru Mirim is a sleepy backwater that offers little to entice adventurous expats. The real draw here is the local dinosaur fossils, with the Itapecuru Formation yielding remains of sauropods, theropods, crocodiles, turtles, and fish dating back to the Early Cretaceous. However, this geological treasure trove comes with a persistent bureaucratic headache, as the complex permitting process to access the fossil sites is enough to deter all but the most dedicated paleontologists. For the average person seeking an exciting new life abroad, Itapecuru Mirim is best left to the dino-hunters.
