sedimentary
Coal is a type of sedimentary rock that is formed from compressed plants. Over millions of years, layers of plant material are buried and compacted under pressure, eventually transforming into coal through a process called coalification.
Sedimentary rocks are made out of sediments.

it is made of dead animals and dead plants
The only good example of this is chalk, which is made from the compacted shells of tiny marine organisms called diatoms. Other than that, animal and plant remains do not tend to form rocks, although the hard parts may form fossils.

Bituminous coal is an organic sedimentary rock formed from the partially decayed remains of plants. Anthracite coal is considered metamorphic rock, and is derived from a bituminous coal protolith. Coal.
