Nether fossils stick from ground surface instead of being partially submerged. This doesn't look natural as most nether fossils are vertically sticking from ground and not laying on the ground.
Image to explain. Left side fossil is naturally generated. It "grows" from surface of soulsand. On the right is fossil made by me. It has underground part. Naturally generated fossils in 20w06a are missing underground part. All start from surface.
This bug also creates situations, where fossils float above ground.
