He likes to dig a lot and sometimes finds fossils that are tens of thousands of years old from the last ice age.
He has a collection of these fossils in a cave. One fossil isn't like the others and may be a dinosaur fossil from the age of dinosaurs.
The wandering shaman that visits this pack (transformed as a wolf) is certain that it's a fossil of the rampaging ghost tyrannosaur that he is trying to get rid of. The shaman is presented a subquest from Dig to collect 30 bones to trade for it.
