Megalodon tooth 3d scan I found on SketchFab and a 3d scan of a rock from my backyard. Combined them together to make a fossil that looks like it's just been found in the rock.
Layer Height: 0.2mm or lower. The lower, the more realistic the rock and fossil will look. 0.2mm should be plenty.
The author remixed this model.
Took the 3d scan and placed it into a 3d scan of a stone to make it look as though it was partially exposed in rock
