Carboniferous coal was produced by bark-breaking trees that grew in lowland swamp forests. Types of vegitation in the swamp included; giant club mosses, tree ferns, horsetails and giant trees. Over millions of years, the organic deposits of the plant's debris foarmed coal deposits. This process preserved plant remains very well
This is an example of Carbonization of plant material. This takes place when an organism is buried in layers of sediment.Over time a chemical reaction occurs which turns most of the elements making up the body of the organism to gas. What is left behind is a carbon residue that usually leaves an outline of the organism on the rock formed by the sediment.
