In paleontology, an Elvis taxon (plural Elvis taxa) is a taxon which has been misidentified as having re-emerged in the fossil record after a period of presumed extinction, but is not actually a descendant of the original taxon, instead having developed a similar morphology through convergent evolution. This implies the extinction of the original taxon is real, and one taxon containing specimen from before and after the extinction would be polyphyletic.
