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 ...
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 ...
A ghost lineage is any gap in a taxon's fossil record, with or without reappearance, while a Lazarus taxon is a type of ghost lineage wherein a species is believed to have gone extinct due to an absence of it in the fossil record, but then reappears after a period of time. [2]
A Lazarus taxon or Lazarus species refers to instances where a species or taxon was thought to be extinct, but was later rediscovered. It can also refer to instances where large gaps in the fossil record of a taxon result in fossils reappearing much later, although the taxon may have ultimately become extinct at a later point.
In contrast to "Lazarus taxa", a living fossil in most senses is a species or lineage that has undergone exceptionally little change throughout a long fossil record, giving the impression that the extant taxon had remained identical through the entire fossil and modern period.
A member of the Lazarus family (the ones who started Lazarus department stores) vacationed in Lake Garda, Italy with his family in 1951. That child was George Rau Jr., stepson of Fred Lazarus III.
The single extant species of tuatara [a] is the only surviving member of its order, which was highly diverse during the Mesozoic era. [13] Rhynchocephalians first appeared in the fossil record during the Triassic , around 240 million years ago, [ 14 ] and reached worldwide distribution and peak diversity during the Jurassic , when they ...
A 2019 five-year review by the United States Fish and Wildlife Service recommended that the ivory-billed woodpecker be removed from the Endangered Species List due to extinction. Then, in September 2021, the USFWS proposed that the species be declared extinct. A public hearing and two public comment periods followed.
