   Marble is a metamorphic rock that is formed through the alteration of limestone or dolomite by heat and pressure. During this process, the original rock is subjected to high temperatures and pressures that cause the minerals in the rock to recrystallize, resulting in a denser, harder rock with a characteristic smooth and shiny surface. This process generally occurs deep underground, and the resulting marble is typically devoid of any fossilized remains.

   Fossils are the remains or traces of plants or animals that have been preserved in sedimentary rock. In order for a fossil to form, the plant or animal must be buried in sediment shortly after its death, and the sediment must be transformed into rock through the process of lithification. Because marble is formed through metamorphism, rather than through the process of lithification, it is unlikely to contain fossils.

   However, it is possible for marble to contain fossilized remains if the original limestone or dolomite rock contained fossils before it underwent metamorphism. In these cases, the fossils may be distorted or partially destroyed during the metamorphic process, but they may still be present in the resulting marble
