You have to talk to the same dude that taut you how to dig up colored fossils.

You can find dark fossils anywhere after completing the test in rivet ravine:)
dropping fossils are found in dark fossils anywhere around vivosaur island.
if you mean where do you get dark fossils in fossil fighters I usually go to the rivit ravene and go up the first flight of stairs then go to the right until you see another flight of stairs going down. go down there and search I almost always find dark fossils there along with some other rare regular fossils. Ninjapower5`s suggestion: I suggest Mt: lavaflow because its basically a place where dinosaurs use to rome.
Use the explorer kit any where. After you are underground, keep digging at the walls until you find a fossil, it may take a while.
