… are they not fossils of the cyanobacteria
Not by the usual definition. The carbon, etc that used to form the cyanobacteria is completely broken down and formed into miscellaneous hydrocarbons. There’s no petrified remains, nor rock impressions of the bacteria.
FWIW that was always my concept of fossil fuels to begin with.

Not all of them. Some of the carbon atoms will have decayed into (I think) nitrogen.
