Imagine being around before the pyramids were built? This type of tree, the Pinus Longaeva or Bristlecone Pine as it is commonly known, is the world's oldest species of tree. It has been around since before the pyramids! They grow in arid mountain regions and the oldest ones are in the White Mountains of California.
The oldest known tree is "Methuselah," which is 4,789 years old. Its exact location is kept secret by the Parks Service to protect the tree from us humans.
Wow! That's old!!
