A One-Million-Year-Old Kakapo Ancestor Unearthed in a New Zealand Cave

Discovery in Caves Across Australia and New Zealand

According to НВ — Техно: A team of researchers from Australia and New Zealand has uncovered the remains of 12 bird species and 4 frog species inside a cave, dating back roughly one million years. This find fills a significant gap in the fossil record, offering rare insight into the region’s ancient ecosystems. The findings were published in the scientific journal Alcheringa: An Australasian Journal of Palaeontology.

Species Identified

Among the recovered fossils is a previously unknown extinct ancestor of the kakapo parrot, named Strigops insulaborealis. Compared to the modern kakapo, this species had weaker legs. The cave also yielded the remains of an extinct ancestor of the takahē bird and an ancient pigeon related to Australia’s bronze-winged pigeons.

The age of the fossils was determined using layers of volcanic ash:

• The lower layer was formed by an eruption 1.55 million years ago;
• The upper layer dates to around 1 million years ago.

This cave is the oldest known on the North Island. Research indicates that between one-third and one-half of the species living at that time went extinct due to volcanic eruptions and climate shifts. These fossils, placed in their paleontological context, will help scientists better understand the evolution of birds and frogs that inhabited the area a million years ago.

The cave discovery highlights how crucial fossil studies are for unraveling evolutionary processes that shaped life in the distant past.

Examining such findings can provide fresh data on ecological changes that impacted species diversity in the region, as well as how organisms adapted to shifting environmental conditions. This knowledge, in turn, may inform modern ecological research and biodiversity conservation efforts.

In addition to the remarkable discovery of the kakapo ancestor, similar fossil finds are shedding light on ancient biodiversity across the globe. For instance, a recently unearthed new species of ancient turtles in Patagonia highlights the ongoing significance of paleontological research in understanding evolutionary pathways and environmental adaptations in various regions.
