A fossil is the apparent remains of a giant prehistoric creature.
Fossils randomly generate 15–24 blocks (i.e., at y-coordinates from 40 to 49) underground in Overworld (deserts, swamps, and their variants). Each chunk has a 1⁄64 chance to generate a fossil. They may generate as one of the four variants of skull or one of the four variants of spine.
Fossils are composed of bone blocks, with random blocks removed and some of them replaced with coal ore. They were made with NBT structure block format and they have NBT files of different types of fossils in

Fossil generated on a superflat world. Some bone blocks are removed/replaced with coal ores.
