In 1994, a park ranger abseiling into a sandstone gorge west of Sydney found a stand of trees with waxy, fern-like foliage that turned out to be Wollemi pines, a genus known only from 90-million-year-old fossils and presumed extinct since the age of dinosaurs
A living fossil thought extinct since dinosaurs walked Earth lay hidden in a remote Australian gorge, waiting for a park ranger's abseiling expedition to stumble upon it.
