This unnamed Great Basin bristlecone pine is currently the oldest confirmed tree in the world. It was named the oldest tree in 2012, beating the previous record holder by over 200 years. The tree was cored by Edmund Schulman in the late 1950s, but he did not have a chance to date his sample before he passed away in 1958.The tree’s age was later determined by Tom Harlan in 2010, who was working on the samples Schulman collected before he also died. The tree is still alive, and in 2012 its age was given as 5,062 years.
