Welcome to the forum.

All I can tell you about your bone is that it looks like it might be from a theropod because it's hollow but the wall thickness is a bit thick.   It's too weathered and partial to described it much further.

Hi Garid, the size, shape, 'wall thickness,' channeled/ridged surface roughness, central void, and overall morphology of this item appear to be definitive for fulgurite.
