Carbonized fossils are made of:
ExtremeBDS [4]
Carbonized remains are thin, approximately two-dimensional films of carbon preserved on a flat surface of rock. They are most often black in color, reflecting the fact that they composed mostly of carbon (as is coal, which is also black in color).

I would say the answer is the Carbon remains of the original organism.
