Not Recognised Species and Subspecies

Réunion SolitairPreviously many more species and subspecies were regarded as extinct. A couple of centuries ago a naturalist could gain fame by naming a new species or subspecies. Naturalists were running all over the place trying to name new species and subspecies. The result of this was that they named a subspecies on very little differences within a species or named a species on little or doubtful information. (Wilson 2004)

Nowadays new research, especially DNA research, reveals that many of those so-called species and subspecies are not distinct from other subspecies or species, like e.g. the Réunion Solitaire, the Curaçao Rice Rat and the Dutch Alcon Blue. They are not regarded as a valid species or subspecies anymore!

This page will show you some of those former recognised extinct species or subspecies. Do you know of taxonomic information that will change the status of a certain species or subspecies mentioned on The Sixth Extinction website? Please contact this website.

The Sixth Extinction Database (TSED)

The Sixth Extinction has created a database (TSED 1.0) with currently all known recent mammal extinctions, possible extinctions, extinctions in the wild, rediscoveries, and more. Later versions of this database will include extinctions from all animal and plant groups. The database is free to download in Excel and OpenDocument formats.
