Notiomastodon Notiomastodon Notiomastodon is an extinct proboscidean genus of gomphothere (a distant relative to modern Elephants) endemic to South America from the Pleistocene to the Holocene living for approximately . Proboscideans in South America were first described by Georges Cuvier in 1806 but he failed to give them specific names beyond "Mastodon". It was Fischer in 1814 who gave the “"mastodonte des cordillères"” specimen the first specific name ""Mastotherium hyodon"". In 1824, Cuvier gave the specific names of ""Mastodon andium"" to the ""mastodonte des cordillères"" specimen, and ""Mastodon humboldtii"" to the ""mastodonte humboldien"". Due to the Principle of Priority, this means
Extinct in the wild survival techniques, which are often passed from parents to offspring during parenting, may be lost. While conservation efforts may preserve some of the genetics of a species, the species may never fully recover due to the loss of the natural memetics of the species. An example of a successful reintroduction of an EW species is Przewalski's horse, which as of 2018 is considered to be an Endangered species, following reintroduction started in the 1990s. Extinct in the wild An extinct in the wild (EW) species is one which has been categorized by the International Union for Conservation of Nature as
