What Is the Oldest Tree in the World?

According to carbon dating, Old Tjikko, a spruce tree on Fulu Mountain in Sweden, sprouted around 7542 B.C.E., making it older than written history. But is it the oldest tree in the world?
The title of oldest tree in the world is, surprisingly enough, up for grabs.
Since about 2018, a majestically gnarled bristlecone pine in California has held the designation, only to be usurped by a new up-and-comer discovered on a Swedish mountaintop. Not to be outdone, a controversial find in a Chilean forest has tree aficionados wondering whether an ancient cypress could actually be hundreds — yes, hundreds — of years older than any known living tree in existence.
