Ammonite s fit these demands well, and are the best-known fossils that have been widely used for this. Other important groups that provide index fossils are the Coral s, Graptolite s, Brachiopod s, Trilobite s, and echinoids ( Sea Urchin s). Conodont s may be identified by experts using light Microscopy such that they can be used to index a given sample with good resolution. Testrial fossils, such as the Teeth of Mammal s, have also been used. Geologist s use both large fossils (called macrofossils) and microscopic fossils (called microfossils) for this process, known as Biostratigraphy . Macrofossils have the advantage of being easy to see in the field, but they are rarer, and microfossils are very commonly used by Oil prospectors and other industries interested in Mineral resources when accurate knowledge of the age of the rocks being looked at is needed. Common Index Fossils In Popular Culture Musical Group Bad Religion have a song titled "Part IV (The Index Fossil)" on their 1987 album '' Suffer ''. The song suggests that one day Humanity will be "an index fossil buried in {Link without Title} own debris". References and Links |
