Zombie taxon

From Wikipedia, the free encyclopedia
Jump to: navigation, search

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