Oldest Living Organisms

The Methuselah tree in California, USA, is the oldest living organism (4,800 years old)known today.  
Methuselah is a 4,846-year-old Great Basin bristlecone pine(Pinus longaeva) tree growing high in the White Mountains of Inyo County in eastern California. For many years it was the world's oldest known living non-clonal organism, until superseded by the discovery in 2013 of another bristlecone pine in the same area with an age of 5,064 years (germination in 3051 BC).
