Macrofossils (occasionally spelled "macro-fossil") are preserved organic remains large enough to be visible without a microscope. Most fossils discussed in the article Fossil are macrofossils.

Macrofossil contrasted with MicrofossilEdit

The term macrofossil stands in opposition to the term microfossil (a.k.a. "micro-fossil"). Microfossils, by contrast, require substantial magnification for evaluation by fossil-hunters or professional paleontologists. As a result, most fossils observed in the field and most "museum-quality" specimens are macrofossils.

Plant MacrofossilsEdit

Plant macrofossils include leaf, needle, cone, and stem debris; and can be used to identify types of plants formerly growing in the area. Such botanical macrofossil data provide a valuable complement to pollen and faunal data that can be used to reconstruct the prehistoric terrestrial environment. Algal macrofossils (for instance, brown kelp, sea lettuce and large stromatolites) are increasingly used to analyze prehistoric marine and aquatic ecosystems.

Animal MacrofossilsEdit

Animal macrofossils include the teeth, skulls, and bones of vertebrates, as well as such invertebrate remains as shells, tests, faunal armor, and exoskeletons. Fossilized dung (that is, coprolites) are also macrofossils.
