context_page_description: This timeline of extinctions is an historical account of species that have become extinct during the time that modern humans have occupied the Earth.
  The following is a selective list made by sampling a very small proportion, mostly mammals, of some of the well-known extinct species in recent history. The vast majority of extinctions, though, are thought to be undocumented. According to the species-area theory and based on upper-bound estimation, the present rate of extinction may be up to 140,000 species per year. See Holocene extinction for more information.
  The Holocene is considered to have started at the Holocene glacial retreat main event at 9700 BCE. Species had also become extinct due to human activity before that date.
context_section_description: c. 2915 BCE - The canid Dusicyon avus survived in Argentina until about this time.
  c. 2835 BCE – The Balearic cave goat became extinct around this time.
  c. 2765 BCE – The North African buffalo Pelorovis antiquus survived until about this time. Its extinction may have been caused by competition for food and water with domestic cattle.
  c. 2550 BCE – The Bennu heron became extinct around this time, possibly due to degradation of its wetland habitat. It was last recorded in the Arabian Peninsula.
  c. 2441 BCE – The sloth Neocnus comes survived in Haiti until about this time.
  c. 2240 BCE – The sloth Megalocnus rodens and the Cuban cave rail survived in Cuba until about this time.
