Lazarus taxa are observational artifacts that appear to occur either because of (local) extinction, later resupplied, or as a sampling artifact.The fossil record is inherently sporadic (only a very small fraction of organisms become fossilized, and an even smaller fraction are discovered before destruction) and contains gaps not necessarily caused by extinction, particularly when the number of ...
Eucanthus lazarus is a species of earth-boring scarab beetle in the family Geotrupidae. It is found in North America. It is found in North America. [ 1 ] [ 2 ] [ 3 ]
Restoration of the skull of the Menat specimen of Lazarussuchus in dorsal and lateral views. Lazarussuchus was small and superficially lizard like in appearance, with the total preserved body and tail length of L. inexpectatus being just over 30 centimetres (0.98 ft), and a skull length of around 4.5 centimetres (1.8 in) [1] According to Matsumoto and colleagues (2013) Lazarussuchus is ...

Species that were once considered extinct and then reappear unscathed are characterized by the term "the Lazarus effect", or are also called a Lazarus species. [6] For example, a study determined that 36% of supposed mammalian extinction had been proven, while the other 64% had insufficient evidence to be declared extinct or had been ...

By contrast, a Lazarus taxon is one that really is a descendant of the original taxon, and highlights transitional fossil records, which might be found later.. A zombie taxon has been considered a Lazarus taxon because it has been collected from younger strata, but it later turns out to be a fossil that was freed from the original seam and was refossilized in a sediment of a younger age.
Functional extinction is the extinction of a species or other taxon such that: . It disappears from the fossil record, or historic reports of its existence cease; [1]; The reduced population no longer plays a significant role in ecosystem function; [2] [3] [4]
