Biography

Worthy grew up in Broadwood, Northland, and went to Whangarei Boys' High School. [1] He began his career as a largely self-taught palaeontologist, after becoming interested in fossils through caving. [2] Worthy completed his BSc and MSc at the University of Waikato, then did a second Master's degree at Victoria University of Wellington. [1]

In 1987, Worthy described three new leiopelmatid frog species from cave subfossils: the Aurora frog ( Leiopelma auroraensis ), Markham's frog (Leiopelma markhami), and the Waitomo frog (Leiopelma waitomoensis). In the 1990s, he discovered several fossil bird species new to science, including the long-billed wren (Dendroscansor decurvirostris) in 1991, Scarlett's shearwater (Puffinus spelaeus) in 1991, and the Niue night heron (Nycticorax kalavikai) in 1995. In 1991, he also described the Northland skink, a fossil skink species new to science. [3]

In 1998, Worthy excavated subfossil bones in Fiji, where he found remains of the flightless Viti Levu giant pigeon (Natunaornis gigoura), the Viti Levu scrubfowl (Megapodius amissus), the Viti Levu snipe (Coenocorypha miratropica), the giant Fiji ground frog (Platymantis megabotoniviti), and the small freshwater crocodile Volia athollandersoni . The holotypes of these species were deposited in the Museum of New Zealand Te Papa Tongarewa.

For years, Worthy has been involved in the excavation of Miocene fossils (the Saint Bathans Fauna) from a prehistoric lake in Central Otago, including the oldest known moa bones, the oldest tuatara bones, and the first known fossil land mammal from New Zealand. [4]

Worthy's research, based in Waitomo Caves, Masterton, Nelson, and Te Papa, had been funded by grants from the Foundation for Research, Science and Technology since 1991, but in 2005 his funding was cut by the Foundation. [2] From 2005 to 2009, he was at the University of Adelaide, where he received his PhD in 2008. He received a Doctor of Science from the University of Waikato in 2011. [1] He was at the University of New South Wales from 2009 to 2011, back at the University of Adelaide during 2012, and has been at Flinders University since 2013. In May 2019, he ended his 30-year research association with Te Papa at protest to the staff restructuring controversy. [5]

Worthy is author or co-author of numerous research papers about prehistoric life in New Zealand. For the book The Lost World of the Moa (2002), he and Richard Holdaway received the D. L. Serventy Medal from the Royal Australasian Ornithologists Union in 2003 for an outstanding published work about Australasian avifauna.

Moa Extinct order of birds

Moa were nine species of now-extinct flightless birds endemic to New Zealand. The two largest species, Dinornis robustus and Dinornis novaezelandiae, reached about 3.6 m (12 ft) in height with neck outstretched, and weighed about 230 kg (510 lb) while the smallest, the bush moa, was around the size of a turkey. Estimates of the moa population when Polynesians settled New Zealand circa 1300 vary between 58,000 and approximately 2.5 million.

The New Zealand swan or poūwa is an extinct indigenous swan from the Chatham Islands and the South Island of New Zealand. Discovered as archaeological remains in 1889, it was originally considered a separate species from the Australian black swan because of its slightly larger bones, and swans not having been introduced to New Zealand until 1864. From 1998 until 2017, it was considered to be simply a New Zealand population of Cygnus atratus, until DNA recovered from fossil bones determined that it was indeed a separate species, much larger and heavier than its Australian relative.

<i>Leiopelma</i> Genus of amphibians

Leiopelma is a genus of New Zealand primitive frogs, belonging to the suborder Archaeobatrachia. It is the only genus in the monotypic family Leiopelmatidae. The leiopelmatids' relatively basal form indicates they have an ancient lineage. While some taxonomists have suggested combining the North American frogs of the genus Ascaphus in the family Ascaphidae with the New Zealand frogs of the genus Leiopelma in the family Leiopelmatidae, the current consensus is that these two groups constitute two separate families. The four extant species of Leiopelmatidae are only found in New Zealand.

Upland moa Extinct species of bird

The upland moa was a species of moa endemic to New Zealand. It was a ratite, a grouping of flightless birds with no keel on the sternum. It was the last moa species to become extinct, vanishing in 1445 CE, and was predominantly found in alpine and sub-alpine environments.

Hamiltons frog Species of amphibian

The Hamilton's frog(Leiopelma hamiltoni) is a primitive frog native to New Zealand, one of only four extant species belonging to the family Leiopelmatidae. The male remains with the eggs to protect them and allows the tadpoles to climb onto his back where they are kept moist. It is named in honour of Harold Hamilton the collector of the type specimen. The holotype is in the collection of the Museum of New Zealand Te Papa Tongarewa.

Viti Levu giant pigeon Extinct species of bird

The Viti Levu giant pigeon or Fiji giant ground pigeon is an extinct flightless pigeon of Viti Levu, the largest island in Fiji. It was only slightly smaller than the dodo and Rodrigues solitaire and is the first giant, flightless pigeon to be discovered on a Pacific island.

Whitakers skink Species of lizard

Whitaker's skink, also known commonly as Whitaker's New Zealand skink, is an endangered species of skink, a lizard in the family Scincidae. The species is found only in New Zealand.

The long-billed wren was a species of New Zealand wren endemic to the South Island of New Zealand. It was the only species in the genus Dendroscansor. The long-billed wren was a small bird with stout legs and tiny wings. Its reduced sternum suggests that it had weak flight muscles and was probably flightless, like the recently extinct Lyall's wren. Its weight is estimated at 30 g, which makes it heavier than any surviving New Zealand wren, but lighter than the also-extinct stout-legged wren. The bill of this species was both long and curved, unlike that of all other acanthisittid wrens.

The New Zealand stiff-tailed duck is an extinct duck species from New Zealand which is known only from subfossil remains. It was first described as a distinct species by Trevor H. Worthy in 2005.

Volia is an extinct genus of mekosuchine crocodylians from Fiji named in 2002. It was around 2–3 metres (7–10 ft) long. Notwithstanding its comparatively small size, it was probably the apex predator of the Pleistocene ecosystems of Fiji.

Scarlett's shearwater is an extinct species of seabird in the petrel family Procellariidae. Its common name commemorates New Zealand palaeontologist Ron Scarlett, who recognised the bird's subfossil remains represented a distinct species.

Vitirallus watlingi, the Fiji rail or Viti Levu rail, was a prehistoric flightless bird from Fiji, and is the only species in the genus Vitirallus. Vitirallus watlingi is thought to have been about the same size as the bar-winged rail but with a very elongated and slender bill.

The Viti Levu scrubfowl, also known as the Fiji scrubfowl or lost megapode, is an extinct megapode that was endemic to Fiji. The epithet amissus, from Latin "lost", refers to its extinction. Subfossil remains were collected from the Udit cave at Wainibuku on the island of Viti Levu in October 1998 by Trevor Worthy, G. Udy and S. Mataraba, and described by Worthy in 2000. The holotype is held by the Museum of New Zealand.

Megavitiornis altirostris is an extinct, flightless, giant stem-galliform bird that was endemic to Fiji, it is the only known species in the genus Megavitornis. Originally thought to be a megapode, more recent morphological studies indicate a close relationship with Sylviornis of New Caledonia, with both genera belonging to the family Sylviornithidae outside of the Galliformes crown group. It is likely that it became extinct through overhunting shortly after the colonisation of the Fiji Islands by humans.

Leiopelma auroraensis, known as the Aurora frog, is an extinct species of frog that was found in New Zealand. One subfossil of the Aurora frog has been discovered in the Aurora Cave, Fiordland, New Zealand. It measured about 60 mm from the snout to the vent. It is named after the Aurora Cave for where it was found. The other extinct New Zealand frogs are Markham's frog and Waitomo frog. Aurora frog probably was a local form that had evolved from the more widely distributed Markham's frog.

Markham's frog is one of three extinct New Zealand frog species, the others being the Aurora frog and Waitomo frog. Subfossil bones used to describe the species were discovered at Honeycomb Hill Cave, South Island, New Zealand, but it once occurred on both South and North Islands. It is estimated that it grew between 50 and 60 mm from snout to vent and it appears to have been a very robust animal.

The Waitomo frog is an extinct species of the genus Leiopelma from New Zealand.

Northland skink Extinct species of lizard

The Northland skink is an extinct species of skink which was endemic to the Northland Region of North Island, New Zealand. It is known from late Holocene subfossil remains.

The Waitomo Caves Discovery Centre is a museum located in the town of Waitomo in the North Island of New Zealand. The museum is also referred to as the Waitomo Caves Discovery Centre, the Waitomo Museum of Caves and the Waitomo Education Centre.
