1

The first episode of the series where Petra Fina and the gang arrived from the Stone Age year and tries to capture the first Time Shifter named Getalong, and there they meet the prehistoric caveboy named Flint Hammerhead and his father Rocky Hammerhead (in human form). She fossilizes them with her fossilizing gun to preserve them as their fossilized appearances are buried in lava. Years later, their fossils are found by Sarah and Tony Goodman. While Flint and Getalong are defossilized by their uncle Dr. Bernard Goodman, a side-effect of the fossilization has left Rocky as a sentient stone slab with eyes. As Dr. Goodman is unable to restore Rocky to normal, he makes him into a high-tech stone axe that comes in handy when Petra Fina comes to claim Getalong. (Source: Wikipedia)
