Araucaria columnaris is a distinctive narrowly conical tree growing up to 60 m (200 ft) tall in its native habit. The trees have a slender, spire-like crown. [3] The shape of young trees strongly resembles A. heterophylla.
The current record-holders for individual, non-clonal trees are the Great Basin bristlecone pine trees from California and Nevada, in the United States. Through tree-ring cross-referencing, they have been shown to be almost five millennia old. [2] A clonal colony can survive for much longer than an individual tree.
At Curio Bay, logs of a fossilized forest closely related to modern kauri and Norfolk pine can be seen that grew on Zealandia about 180 million years ago during the Jurassic period, before it split from Gondwana. [12] During glacial periods more of Zealandia becomes a terrestrial rather than a marine environment.
