CORE DEFINITION

In paleontology, an Elvis taxon is mistaken for the reappearance of an extinct taxon but is not its descendant; convergent evolution produced a similar morphology. The name invokes Elvis impersonators after his death. It does not mean every morphological misclassification or a business fraud.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Distinguish morphological resemblance from lineage continuity when assessing an apparent reappearance.

anchor

Anchor fast decisions

Convergent evolution creates similar forms. Lumping specimens from unrelated lineages before and after an extinction can create an apparent reappearance.
