Actually... Here is a long journey u have to go to understand the formation of coal
...........
Coal is nothing but a black shaped spherical ball but yeah millions and millions of year ago probably at the Prehistoric age of Dinosaurs and Dinosaurs and other small or large animals that they got the guard it into the soil as you know but this soil or month year by year got formed a layer to layer and so on the after they got compressed into Rock Above The Rock containing the earlier invertebrate fossils
Agaiw millions of year later the bodies of horse like creatures dying in the area are fossil in the rocks above those earlier rocks
Much later by erosion or water flow near survey some of the rocks and expose is the heart structure and physical and big deep under the soil we will get those fossils of Dinosaurs of which some of them has low leakage into coal
