Vedclass · Answer

(A) Coal balls are spherical or irregular masses of mineral matter found in coal seams.They are formed by the infiltration of mineral-rich solutions (like calcium carbonate or silica) into plant tissues before they are compressed into coal.This process preserves the internal cellular structure of the plants in three dimensions,which is characteristic of petrifaction.Therefore,the fossils found within coal balls are primarily of the petrifaction type.
