Have any Nephilim bones ever been found?

Answer 1

However, if they did live before the flood, most, if not all, artifacts and bones would have been destroyed upon absorption into the earth's crust or lost to the depths of the sea. Perhaps some have been found, mixed in among dinosaur bones. Or possibly they were dinosaurs.

No bones have been discovered that have been claimed and proven to be from Nephilim.

Yes. Remains of giant humans were found by "Buffalo Bill" Cody. In his book "AN AUTOBIOGRAPHY OF BUFFALO BILL (COLONEL W.F. CODY)"[1920, Cosmopolitan Book Corporation] he says:-

CHAPTER VI ........ At Frenchman's Fork we discovered a village, but did not surprise it, for the Indians had seen us approaching and were in retreat as we reached their camping-place.

We chased them down-stream and through the sandhills, but they made better time than we did, and the pursuit was abandoned.

While we were in the sandhills, scouting the Niobrara country, the Pawnee Indians brought into camp some very large bones, one of which the surgeon of the expedition pronounced to be the thigh bone of a human being. The Indians said the bones were those of a race of people who long ago had lived in that country. They said these people were three times the size of a man of the present day, that they were so swift and strong that they could run by the side of a buffalo, and, taking the animal in one arm, could tear off a leg and eat it as they ran.

These giants, said the Indians, denied the existence of a Great Spirit. When they heard the thunder or saw the lightning, they laughed and declared that they were greater than either. This so displeased the Great Spirit that he caused a deluge.The water rose higher and higher till it drove these proud giants from the low grounds to the hills and thence to the mountains. At last even the mountaintops were submerged and the mammoth men were drowned.

After the flood subsided, the Great Spirit came to the conclusion that he had made men too large and powerful. He therefore corrected his mistake by creating a race of the size and strength of the men of the present day. This is the reason, the Indians told us, that the man of modern times is small and not like the giants of old. The story has been handed down among the Pawnees for generations, but what is its origin no man can say.

CHAPTER VII

Other remains have been found, and photographs and videos will be found if "Nephilim Bones" is Googled.

Answer 2

No. No remains of any giant humans, or of humans partly descended from angels, have ever been found, nor are any ever likely to be found. More importantly, no evidence been found of dwellings suitable for for a race of giants, nor any suitably large implements, bowls or artefacts, nor over-sized weapons.
