A fight ensued, which led to the Sharptooth's death. However, the sharptooth left "The Lone Dinosaur" with a scar slashed across his right eye. Soon after the battle, a huge monolith that resembled a proud sauropod, having life-sized Sharptooth teeth arranged around his neck, came out of the ground during an earthshake. The dinosaurs called it "Saurus Rock". The legend also states that if anyone damages the monolith, bad luck would descend upon the valley.
