Definition of pseudoextinction in English:



  • The apparent extinction of a group of organisms with the survival of modified descendant forms.

    • ‘For the purpose of calculating community similarity, species that are part of possible phyletic sequences were synonymized to correct for pseudoextinction.’
    • ‘The subsequent extinction of the family may be a pseudoextinction, because the Palaeoxanthopsidae may have given rise to many of the extant lineages comprising the Xanthoidea.’
    • ‘The nature of mass extinctions in particular has been distorted by a combination of post-extinction sampling bias and associated pseudoextinction of paraphyletic groups.’
