Index fossils (also known as guide fossils or zone fossils) are fossils used to define and identify geologic periods (or faunal stages). These eons are called Triassic, Jurassic and Cretaceous. Index fossils of plant origin are very rare. Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends. They are used for the determination of the age of organic rocks and other fossil assemblages and also help to establish relationships be-tween rock units. Tropites subbullatus (ammonite) Permian.

Tetragraptus fructicosus. Leptodus americanus (brachiopod) Carboniferous. Beds that preserve fossils typically lack the radioactive elements needed for radiometric dating.This technique is our only means of giving rocks greater than about 50 million years old an absolute age, and can be accurate to within 0.5% or better.
