Fossil Vs Index Fossil at Lynn Craig blog

Fossil Vs Index Fossil. Correlation can be determined by using magnetic polarity reversals, rock types, unique rock sequences, or index fossils. Index fossils occur for a limited interval of time. Biostratigraphy is the specific branch of stratigraphy that uses index fossils found in the strata to serve as biological markers and give a more precise estimate of the rock unit's age. Index fossils (also called key fossils or type fossils) are those that are used to define periods of geologic time. These include bones, shells, exoskeletons, stone imprints. To know which the ideal index fossil is, consider one that 1) abundant, 2) is widespread (occurs in many locations in. Index fossils are used to identify key surfaces and transitions between different depositional environments. Index fossil, any animal or plant preserved in the rock record of the earth that is characteristic of a particular span of geologic time or environment. Fossil species that are used to distinguish one layer from another are called index fossils. Every fossil tells us something about the age of the rock it's found in, and index fossils are the ones that tell us the most.
