Trevor Worthy: The Paleozoologist Uncovering New Zealand's Prehistoric Life
Trevor Henry Worthy is a distinguished paleozoologist—a scientist who studies the fossils of ancient animals—whose work has fundamentally reshaped our understanding of extinct vertebrates in New Zealand and the surrounding Pacific. Often affectionately referred to as "Mr. Moa," Worthy has dedicated his career to excavating the remnants of lost worlds, from the depths of limestone caves to the prehistoric lake beds of Central Otago.
His journey into science was unconventional. Growing up in Broadwood, Northland, and attending Whangarei Boys' High School, Worthy began as a largely self-taught paleontologist. His passion for the field was ignited through caving, which led him to discover the hidden fossil records preserved in the earth. This curiosity eventually transitioned into a rigorous academic career, spanning multiple degrees and prestigious university appointments.

A Career of Discovery: From Caves to Continents
Worthy's early professional contributions were marked by the discovery of species previously unknown to science. In 1987, he identified three new species of leiopelmatid frogs from cave subfossils: the Aurora frog, Markham's frog, and the Waitomo frog. By the 1990s, his focus expanded to avian species, where he described the long-billed wren (1991), Scarlett's shearwater (1991), and the Niue night heron (1995), as well as the Northland skink.
Expeditions in Fiji
In 1998, Worthy extended his research to Fiji, excavating subfossil bones that revealed a diverse array of extinct fauna. His findings included the flightless Viti Levu giant pigeon, the Viti Levu scrubfowl, the Viti Levu snipe, the giant Fiji ground frog, and a small freshwater crocodile known as Volia athollandersoni. These critical holotypes—the single physical examples used to formally describe a species—were deposited in the Museum of New Zealand Te Papa Tongarewa.
The Saint Bathans Fauna
One of Worthy's most significant long-term projects involves the Saint Bathans Fauna. These Miocene fossils, found in a prehistoric lake in Central Otago, have provided some of the most important evidence of New Zealand's early biodiversity. Through this work, Worthy helped uncover the oldest known moa and tuatara bones, as well as the first known fossil land mammal from New Zealand.

Academic Journey and Institutional Ties
Worthy's academic path reflects a commitment to lifelong learning. After his early self-taught years and initial degrees in New Zealand, he moved to Australia to further his research. Between 2005 and 2009, he attended the University of Adelaide, earning his PhD in 2008 with a thesis focused on the tertiary fossil waterfowl of Australia and New Zealand. He later held positions at the University of New South Wales and returned to the University of Adelaide before joining Flinders University in 2013.
His relationship with the Museum of New Zealand Te Papa Tongarewa was a cornerstone of his career for three decades. However, in May 2019, Worthy ended this association in protest against a staff restructuring controversy.
