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 evidence - each aspect requires the strongest scrutiny," adding that "High and concentrated forces must have been required to smash the thickest mastodon bones, and the low energy depositional environment seemingly provides no obvious alternative to humans using the heavy cobbles found with the bones." 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
