In 1994, David Noble found unfamiliar trees in Wollemi National Park, northwest of Sydney. The discovery led to the description of Wollemia nobilis, a living member of an ancient conifer lineage.
Ancient ancestry is not an extinction date
Botanic Gardens of Sydney explains that the Araucariaceae family has a long fossil history and that the last relevant Wollemi fossil record dates to about two million years ago. The earlier article confused that history with a claim that the species had been declared extinct for 90 million years.
The genus was scientifically described following the living discovery. It was not a formally named fossil genus already declared extinct 90 million years earlier. Fossil relatives and similar pollen help establish ancestry; they do not justify assuming uninterrupted residence in one modern canyon since the Cretaceous.
Why the location is protected
NSW National Parks describes the species as critically endangered, with fewer than 100 mature trees known in the wild. Their locations are withheld to help protect them, including from disease introduced by visitors.
Low genetic diversity is another conservation concern. It should not be exaggerated into a claim that every tree has precisely the same genome or that a particular pathogen would certainly eliminate all trees within a season.
A discovery and a conservation responsibility
The discovery was remarkable without the inflated timescale. A surviving wild population close to a major city changed botanical understanding and created an immediate obligation to protect a very restricted species.
Cultivated trees help people encounter this lineage without entering the protected wild sites. A tree in a garden is not evidence that the original canyon can safely be opened to visitors.
The lesson is to distinguish what a fossil record documents, what a living discovery establishes, and what conservation requires now. Absence from a fossil sequence does not identify an exact extinction date, and ancient ancestry does not date the current forest.
Correction, 3 October 2026: The earlier article incorrectly said the Wollemi pine had been extinct for 90 million years and that its genus had already been described from fossils. The last relevant fossil record is about two million years old; the living discovery led to the genus’s description. Unsupported claims of identical genomes and uninterrupted residence in the same canyon have also been removed.
