Diamond tools won't help with fossils. Since those are actually placed in the world.
1.Junk-Jack-Wiki 2. The world is big, 256 blocks high and 768 across. 3. Who is John Galt? 4. Lack of objection does not indicate consent. 5. We scream, we shout, we wail, we cry; but in the end we all must die.
My TIP: Mine down to the first level of Jungle/Mushroom Biomes. Then, mine sideways. I've only found Fossils in the Biome-specific blocks, never Normal dirt or stone.
3 of the four fossils I found outside of biomes, the last one i found in the mushroom biome.
