Biology:Zombie taxon

From HandWiki
Short description: Type of fossil
Jurassic ammonite internal mold redeposited (and bored) in a Cretaceous sediment, thus a zombie taxon or remanié; Faringdon Sponge Gravel, England .

In paleontology, a zombie taxon[1][2] (plural zombie taxa) or the zombie effect refers to a fossil that was washed out of sediments and re-deposited in rocks and/or sediments millions of years younger.[3] That basic mistake in the interpretation of the age of the fossil leads to its title,[4] in that the discovered fossil was at some point mobile (or "walking") despite the original organism having been long dead. When that occurs, the fossil is described as a "reworked fossil".
