Got fascinated by these things on the Yosemite trip this year
The bristlecone pines are the oldest single living organisms known (though some plants form clonal colonies which may be many times older). The oldest bristlecone pines are single plants that have been alive for a little less than 5,000 years. These very old trees are of great importance in dendrochronology or tree-ring dating.
The oldest (non-clonal, acknowledged) living organism known is a bristlecone pine tree nicknamed "Methuselah" (after Methuselah, the longest-lived person in the Bible). It is located in the Ancient Bristlecone Pine Forest in the White Mountains of eastern California, however its precise location is undisclosed by the U.S. Forest Service to protect the tree from vandalism.[7] The age of Methuselah was measured by core samples in 1957 to be 4,789 years old.
