Fossils in limestone.
Fossils The abundance of large and well-preserved fossils in Tyndall Stone is another interesting component of the stone. Because of this, Tyndall Stone is sometimes referred to as a fossiliferous limestone. The fossils are more prevalent in some localities than others and are also particularly characteristic of certain beds.
Limestone, or its metamorphic cousin, marble, is rock made primarily of calcium carbonate. These rock types are often formed from the bodies of marine plants and animals, and their shells and skeletons can be preserved as fossils. Carbon locked up in limestone can be stored for millions—or even hundreds of millions—of years.The Carboniferous Period lasted from about 359.2 to 299 million years ago* during the late Paleozoic Era. The term "Carboniferous" comes from England, in reference to the rich deposits of coal that occur there. These deposits of coal occur throughout northern Europe, Asia, and midwestern and eastern North America.Fossiliferous limestone is a limestone that contains obvious and abundant fossils.
