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 ...
As of 2019, the Catalogue listed 1.9 million extant and extinct species. [13] There are an estimated 14 million mainly unpublished species; however, this number is uncertain as there is a lack of data on the possible number of undescribed insects, nematodes, bacteria, fungi and many others.

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 ...
On September 17, 2023, the project reached 850,000 articles, and a total of 1.87 million pages. [4] As a database for taxonomy and nomenclature, Wikispecies comprises taxon pages, and additionally pages about synonyms, taxon authorities, taxonomical publications, type material, and institutions or repositories holding type specimen.

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.
The Laotian rock rat or kha-nyou [2] (Laonastes aenigmamus, Lao: ຂະຍຸ), sometimes called the "rat-squirrel", is a species of rodent found in the Khammouan region of Laos. The species was first described in a 2005 article by Paulina Jenkins and coauthors, who considered the animal to be so distinct from all living rodents, they placed it ...
