Elvis taxon 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 specimens from before and after the extinction would be polyphyletic. == Etymology == The term Elvis taxon was coined by D.H. Erwin and M.L. Droser in a 1993 paper to distinguish descendant from non-descendant taxa: "Rather than continue the biblical tradition favored by Jablonski (for Lazarus taxa), we prefer a more topical approach and suggest that such taxa should be known as Elvis taxa, in recognition of the many Elvis impersonators who have appeared since the death of The King."〔Erwin, D.H. and Droser, M.L., 1993. Elvis taxa. PALAIOS, v.8, p.623-624.()〕
