Coelacanth eggs are large, with only a thin layer of membrane to protect them. Embryos hatch within the female and eventually are born alive, which is a rarity in fish. This was only discovered when the American Museum of Natural History dissected its first coelacanth specimen in 1975 and found it pregnant with five embryos. [70]
The takahē of New Zealand had not been seen since 1898 when it was rediscovered in 1948.. In paleontology, a Lazarus taxon (plural taxa) is a taxon that disappears for one or more periods from the fossil record, only to appear again either in later fossil records, or as actual living organisms, and often in isolated, obscure, or otherwise very specialized habitats.
A bird species found in mainland Europe and the Mediterranean is thought to be extinct globally by a coalition of conservation groups. ... “Extinction is forever. This news highlights that our ...
Some mammals declared as extinct may very well reappear. [1] For example, a study found that 36% of purported mammalian extinction had been resolved, while the rest either had validity issues (insufficient evidence) or had been rediscovered. [3] As of December 2015, the IUCN listed 30 mammalian species as "critically endangered (possibly ...

The shy Australian animals died after only a century of European settlement. Despite the world's last captive thylacine dying in 1936, the secretive animal wasn't declared extinct until 1986.
This is the only specimen photographed alive. The quagga (Equus quagga quagga) became extinct in the wild in the late 1870s due to hunting for meat and skins, and the subspecies' endling died in captivity on 12 August 1883 at the Artis in Amsterdam. [17] The final tarpan (Equus ferus ferus) died in captivity in the Russian Empire in 1903. [18]
All of these were described from fossils before later being found alive. [15] [16] [17] The fact that a living fossil is a surviving representative of an archaic lineage does not imply that it must retain all the "primitive" features (plesiomorphies) of its ancestral lineage. Although it is common to say that living fossils exhibit ...
