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
Cerutti Mastodon site Cerutti Mastodon site The Cerutti Mastodon site is a paleontological and possible archeological site located in San Diego County, California. In 2017, researchers announced that broken mastodon bones at the site had been dated to around 130,700 years ago. Since the bones were found with cobblestones displaying use-wear and impact marks among the otherwise fine-grain sands, intentional breakage of the bones by hominins using the stones has been suggested by the researchers. If this is so, then some form of "Homo" may have been present in the Americas at an extremely early age. The Cerutti Mastodon site (SDNHM locality 3767)
