In Fossil Fighters, to find the Coatlus Arms in Rivet Ravine, head to the area known as the "Giant's Grave." Look for the fossil digging spots located on the cliff sides and in the rocky outcrops. Use your digging tools to uncover the Coatlus Arms fossil. Remember to keep an eye out for any enemies while you search!
