Pando, a colony of quaking aspen, is one of the oldest-known clonal trees. Recent estimates of its age range up to 14,000 years old, and 18,000 years by the latest (2024) estimate. [1] It is located in Utah, United States. This is a list of the oldest-known trees, as reported in reliable sources. Definitions of what constitutes an individual ...
The colony has survived an estimated 13,000 years through clonal reproduction, [3] [4] [5] making it one of the world's oldest living trees. [5] The oak was discovered by botanist Mitch Provance in the 1990s and at the time he recognized it as disjunct for the species and likely an “ancient” clonal stand. [6]
A dendrochronology, based on these trees and other bristlecone pine samples, extends back to about 9000 BC, albeit with a single gap of about 500 years. [20] [3] An older bristlecone pine was reportedly discovered by Tom Harlan in 2009, based on a sample core collected in 1957. According to Harlan, the tree was 5,062 years old and still living ...
Argentina – the Sarmiento Petrified Forest and Jaramillo Petrified Forest in Santa Cruz Province in the Argentine Patagonia have many trees that measure more than 3 m (9.8 ft) in diameter and 30 m (98 ft) long. [38] Brazil: in the geopark of Paleorrota, there is a vast area with petrified trees. [39] In the Heritage forest

Unusual trees found fossilized in Canada were buried alive 350 million years ago. Scientists say the discovery opens a new window into the history of life on Earth. Rare ancient tree discovery has ...
This complex tree ring data allowed the scientists to reconstruct annual temperatures for Northern Hemisphere summers between the years 1 and 1849 and compare them to last summer’s temperatures.
