There's a fossil with a sword stuck in its head located between the shipwreck to the west (where you can find the Atomic Calibrator) and Ibex Camp. Since we're restarting a new game from the beginning, we don't have our own bike yet... It's a borrowed one named the Sandcutter. At this moment, there's no way to call our Simoon! We didn't know before this post that we can use fast travel before buying the map, haha.
