Araucaria (/ æ r ɔː ˈ k ɛər i ə /; original pronunciation: [a.ɾawˈka.ɾja]) [2] is a genus of evergreen coniferous trees in the family Araucariaceae.While today they are largely confined to the Southern Hemisphere, during the Jurassic and Cretaceous they were globally distributed.
The root system is extensive. A tiny seedling may quickly send a taproot down 60 centimeters (24 in) seeking moisture and nutrients. A mature tree may have roots extending 75 meters (246 ft). Exposed trees battered by coastal winds are often twisted into beautiful sculptural shapes resembling large bonsai, and rarely exceed 12 m (39 ft) tall.
The green pine needles give the twisted branches a bottle-brush appearance. The needles of the tree surround the branch to an extent of about one foot near the tip of the limb. [13] The name bristlecone pine refers to the dark purple female cones that bear incurved prickles on their surface. [5] [12] The dark color of these cones helps to ...

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 ...
