Coal only got there specifically because there was nothing evolved to eat lignin for a long time and dead trees piled up so high that dead trees on top ended up compressing their ancestors into it.

I thought this hypothesis was disproved and it was some geological process that buried the trees? I remember there was a study about lignin content in other fossils and it was compatible with fungi decomposing wood.

The trees got buried in oxygen-free peat bogs where decomposers could not survive.
