Prehistoric reptiles
Thomas Cockburn-Hood finds marine elasmosaur and mosasaur fossils in South Island.
Hunting for dinosaurs
Geologist Alex McKay searches for fossils in the South Island. Finds fossils of marine reptiles, but no dinosaurs.
Joan born
Brought up in King Country and Hawke’s Bay. Original surname is Pedersen, but she becomes well known later under her married name, Wiffen.
Joins WAAF
Joins Women’s Auxiliary Air Force. Continues to work as a clerk after leaving WAAF in 1944.
Family and farming
Marries M A Wiffen, known as ‘Pont’, a technician at local radio station. They later move to small farm in Hawke’s Bay. Joan works on farm and in the home, bringing up two children. Pont continues with electronics work as well.
Dinosaur fossil found
In 1955 geologist and palaeontologist Charles Fleming discovers a piece of bone in Mikonui Stream, Canterbury. Many decades later that piece of bone has been unofficially identified as that of a pterosaur. This date remains tentative as tangata whenua or others may have made earlier, unknown discoveries of pterosaur fossils.
Reptile fossils reported
An oil company survey by Don Haw reports reptile fossils near the Mangahouanga Valley in Hawke’s Bay. No-one follows this up at the time, but it stimulates Joan Wiffen to search the area in the 1970s.
Ancient Gondwana
Ancient continent of Gondwana thought to be made up of South America, Africa, India, Australia, Antarctica and New Zealand. Dinosaur fossils have been found everywhere except Antarctica and New Zealand.
Evening classes
Joan starts going to art evening class, while Pont does geology. Pont becomes ill, so Joan goes to geology in his place.
Leave farm
Pont becomes very ill, so they leave the farm and move to Haumoana, on the coast near Clive, Hawke’s Bay.
Where are New Zealand dinosaurs?
GNS Science
Charles Fleming suggests that dinosaur fossils may exist in New Zealand, they just haven’t been found yet.
Visit Australia
After Pont’s recovery, they make long trip to Australia, including mineral and rock collecting. Joan gets ‘fossil hunting bug’, and family visits many New Zealand fossil sites over next few years.
No dinosaurs in New Zealand
No dinosaur fossils have been found in New Zealand. Perhaps they never lived in this part of Gondwana, or they did live here but no evidence has been found yet.
Mangahouanga
Julian Thomson, GNS Science
Joan and Pont Wiffen’s first trip to Mangahouanga, inland Hawke’s Bay. They find many fossils in Late Cretaceous rocks, including fish, shark, belemnites, molluscs.
First fossil bone
Return visits continue to turn up many marine fossils, including species not found in New Zealand (or anywhere else) before. Pont finds first fossil bone (plesiosaur vertebra).
Important finds
Find mosasaur skull (given scientific name Moanasaurus mangahouagae in 1980) and an unusual fossil that is later identified as toe bone of small dinosaur (therapod).
Mangahouanga hut
Build hut to stay in when working at Mangahouanga, with other members of a growing team from the Hawke’s Bay Paleontological Group.
New vertebra
The University of Waikato Te Whare Wānanga o Waikato
Fossil vertebra found, but unable to identify it. In 1979, Australian scientist Dr Ralph Molnar identifies it as from an ankylosaur.
Plesiosaur skull
Complete skull of plesiosaur found, though not extracted from rock until 1984.
Dinosaurs in New Zealand
Joan Wiffen’s discoveries and work to identify discoveries by colleagues and others, show dinosaurs lived in New Zealand after it split away from Gondwana in the Early Cretaceous.
Gondwana evidence
Neville Gardner
Fossil leaves of Glossopteris found in Southland. This plant is used to identify lands once part of Gondwana.
Dinosaur announcement
Dr Ralph Molnar gives first talk about dinosaur fossil finds in New Zealand at conference in Wellington – there are no local experts to do this. Little response from scientists, but great response from public.
Turtle fossils
First Cretaceous turtle fossils in New Zealand described from Mangahouanga.
Reptile finds
Lloyd Homer, GNS Science
Dr Ewan Fordyce of Otago University finds almost complete elasmosaur skeleton near Dunedin. Also plesiosaur and mosasaur fossils.
Book published
Book Valley of the dragons is published – part autobiography, part description of dinosaurs and other fossils at Mangahouanga.
Dinosaur in Antarctica
First dinosaur fossil (from an ankylosaur) found in Antarctica. This means that dinosaur fossils have now been found in all lands that once made up Gondwana.
Flying reptile
The University of Waikato Te Whare Wānanga o Waikato
Trevor Crabtree finds this pterosaur fossil at Mangahouanga. It is identified and published by Joan Wiffen and Ralph Molnar in 1988.
Charles Fleming’s possible pterosaur bone found in 1955 has yet to be formally identified and described – until such a time, the Crabtree specimen will remain as the first dinosaur fossil found in Aotearoa.
New mosasaurs
The University of Waikato Te Whare Wānanga o Waikato
Joan names two new species of mosasaur found at Mangahouanga – Rikisaurus tehoensis and Mosasaurus flemingi.
Fossil review
With Ralph Molnar, Joan publishes an important review paper: A late Cretaceous polar dinosaur fauna from New Zealand.
Awards
Joan receives honorary doctorate from Massey University and Science and Technology Bronze Medal from Royal Society of New Zealand.
Jurassic dinosaur
Brendan Hayes’s single Jurassic fossil shows dinosaurs lived in New Zealand before it moved away from Gondwana.
Jurassic dinosaur
Brendan Hayes finds single fossil bone from small therapod near mouth of Waikato River. This is the only Jurassic period dinosaur found in New Zealand, 70 million years older than the Hawke’s Bay fossils.
CBE
Joan is made Commander of the British Empire.
Titanosaur
The University of Waikato Te Whare Wānanga o Waikato
Joan finds fossil bone of titanosaur at Mangahouanga.
Crocodiles and mammals
Trevor Worthy and an international team find new Miocene fossils in Central Otago. These include a crocodile and New Zealand’s earliest (tiny) mammal, which was not announced until 2006.
Book and film
NZPA
Joan publishes book Dinosaur New Zealand with writer and artist Geoffrey Cox. Joan’s achievements celebrated in Red Sky’s documentary film The lost dinosaurs of New Zealand.
Chatham Island dinosaurs
Jeffery Stilwell, Chris Consoli and others of Monash University, Melbourne, find fossil bones from small theropod dinosaur in Chatham Islands.
American award
Joan receives Morris Skinner Award from US-based Society of Vertebrate Paleontology for her contributions to scientific knowledge.
Dinosaurs widespread
Fossil bones in the Chatham Islands and fossil footprints near Nelson show dinosaurs were widespread in ancient New Zealand.
Dinosaur footprints in New Zealand
GNS Science
Footprints of Late Cretaceous sauropods found near Nelson. First evidence of dinosaurs from South Island and first footprints in New Zealand. Find out more in this article, Ancient dinosaur footprints discovered near Nelson.
Joan dies
Joan dies in Havelock North, aged 87. Tributes sent in from all round the world.
Work to continue
Julian Thomson, GNS Science
Scientists from GNS visit Mangahouanga and meet with landowners to consider ways of continuing Joan’s investigations.
Transcript
Changing scientific ideas
Each specialised field of science has key ideas and ways of doing things. Over time, these ideas and techniques can be revised or replaced in the light of new research. Most changes to key science ideas are only accepted gradually, tested through research by many people.
Advances in science and technology
All scientists build their research and theories on the knowledge of earlier scientists, and their work will inform other scientists in the future. A scientist may publish hundreds of scientific reports, but only a few are mentioned here.
Biography
This part of the timeline outlines just a few events in the personal life of the featured person, some of which influenced their work as a scientist.
