The Mount Owen Claw: A Glimpse into the Past

Within the rugged landscapes of New Zealand, a mesmerizing tale unfolds—the Mount Owen Claw. Join us on an extraordinary journey as we unravel the mysteries surrounding this eerie discovery, providing a remarkable window into the prehistoric world. Walk with us through the annals of time and explore the ascent, decline, and potential reawakening of the enigmatic upland moa.

A Journey into the Depths

Almost three decades ago, a daring team of archaeologists embarked on a remarkable expedition deep within the cavernous recesses of Mount Owen. As they ventured further into the dark cave, they encountered a sight that sent shivers down their spines. Amidst the darkness, they stumbled upon an enormous claw, reminiscent of a dinosaur’s, astonishingly well-preserved with flesh and scaly skin. Its eerie presence left them in awe, pushing the boundaries of reality. Could such a creature still inhabit these uncharted territories?

An Enigmatic Revelation

With bated breath, the archaeologists retrieved the mysterious claw, eager to unravel its enigmatic origin. The results were nothing short of astonishing. Radiocarbon dating uncovered the claw’s true identity—it was the mummified remains of an upland moa, a colossal prehistoric bird that had vanished from existence over three millennia ago.

The Upland Moa: Forgotten Giant

The upland moa, scientifically known as Megalapteryx didinus, was a remarkable species of moa bird indigenous to New Zealand. Recent DNA analysis, as published in the Proceedings of the National Academy of Sciences, has indicated that the first moa appeared over 18.5 million years ago, giving rise to at least ten distinct species. Nevertheless, they faced one of the fastest human-facilitated megafauna extinctions in history.

Some sub-species of moa stood tall at over 10 feet (3 meters), making them the largest birds to ever grace the planet. In contrast, the upland moa, one of the smaller moa species, reached no more than 4.2 feet (1.3 meters) in height. These remarkable creatures were covered in feathers, save for their beaks and soles, devoid of wings and tails, and comfortably inhabited the higher, cooler regions of New Zealand.

The tale of the moa begins in 1839 when John W. Harris, a flax trader with an affinity for natural history, received an unusual fossilized bone from a member of the indigenous Māori tribe. This bone, discovered on a riverbank, was a riddle that perplexed the scientific community. It found its way to Sir Richard Owen, a prominent figure at the Hunterian Museum, Royal College of Surgeons, London.

For four years, Owen grappled with this intriguing bone, which seemed to defy categorization. Eventually, his perseverance paid off, as he declared it to be the bone of a previously unknown giant bird. Though initially ridiculed, Owen’s theory was later vindicated through the discovery of numerous moa bone specimens, enabling the complete reconstruction of a moa skeleton.

Since that pioneering discovery, thousands of moa bones have come to light, some of which are astonishingly preserved, including the eerie Mount Owen claw. Some specimens still bear soft tissue, replete with muscle, skin, and even feathers. Most of these fossilized remains were uncovered in dunes, swamps, and caves, where these birds may have sought refuge from adverse weather conditions, ultimately preserved through desiccation.

The Moa’s Triumph and Tragedy

When Polynesian voyagers first reached New Zealand in the 13th century, the moa population thrived. These colossal herbivores ruled over New Zealand’s forests, shrublands, and subalpine ecosystems for millennia, facing just one formidable predator—the Haast’s eagle. However, with the arrival of humans on these pristine shores, the moa’s fate took a perilous turn.

These giants of the avian world matured at a glacial pace, unable to reproduce quickly to maintain their populations. Over-hunting and habitat destruction left them on the brink of extinction. By the time Europeans set foot in New Zealand in the 1760s, the moa had vanished from the face of the Earth, and the Haast’s Eagle, reliant on the moa for sustenance, soon followed into the annals of extinction.

Reviving the Moa: A Glimmer of Hope

The possibility of reviving the moa has tantalized scientists and dreamers alike. The presence of well-preserved remains offers a ray of hope. Since the moa’s extinction is a relatively recent event in geological time, many of the plants that once constituted their diet still flourish.

Japanese geneticist Ankoh Yasuyuki Shirota has taken the first steps towards this ambitious endeavor by extracting DNA from moa remains. His plan is to introduce this genetic material into chicken embryos, rekindling the moa’s existence. Interest in this resurrection gained momentum when Trevor Mallard, a Member of Parliament in New Zealand, suggested that the moa could be revived over the next half-century.



The Mount Owen Claw serves as an eerie yet fascinating portal to the world of the upland moa. These colossal, flightless birds, once rulers of New Zealand’s wilderness, met a tragic end at the hands of humans. Yet, the dream of their revival now beckons, and the ancient avian giants may yet find their place in the modern world.
