Elvis taxon

An Elvis taxon (plural taxa) is a term used in taxonomy. It is similar to a Lazarus taxon and often confused with it. Where Lazaraus taxa are those that have seemingly returned from the dead after a mass extinction, Elvis taxa are the decendants of different groups that are known to have survived the extinction and have evolved to closely resemble the extinct group through convergent evolution. The term Elvis taxon is used because although Elvis is truly dead, he has many imitators.
