To the east of Fallarbor Town on Route 114, there is a house (Fossil Maniac's house). Inside, just before the cave, is fossil maniac's little brother, who will give you the TM dig.
(After defeating the Elite Four, you may also find the fossil that you didn't pick up in Mirage Tower. It is in the cave behind the Fossil Maniac, which is called Desert Underpass. In this cave is also Ditto, Whismur, and Loudred. [That is in order of least rare to most rare.])
