To the east of the National Park near Goldenrod, there is a tree which is actually a Sudowoodo. After defeating/capturing it, go right and talk to the first man you see. He'll hand you the HM Rock Smash. That route is also a quick shortcut to Violet City.
You have to trade it from HeartGold, in the ruins of alph when you use rock smash on the rocks you can find the Dome Fossil(for kabuto) but that's only for SoulSilver, the Helix Fossil(for Omannyte) is only found in HeartGold
