Tributes came in from around the world when Joan Wiffen died in 2009. She was the woman who found the first dinosaur fossils in New Zealand and rewrote the way we understand the country’s past. Joan achieved this fame as an amateur scientist, not a professional. She received numerous honours and awards, wrote scientific publications and popular books and had a documentary film made about her life. Yet all this only happened in the later part of her life.

These were priceless treasures from the past – and, suddenly, I was hooked. I knew what I wanted – to collect fossils.

Joan Wiffen

Joan’s early life was typical of many women born in the 1920s. Her parents saw no need for further education, so Joan left school and worked as a clerk, got married, brought up two children and helped her husband on their small farm.

It wasn’t until 1972 that a growing interest in rocks and fossils led Joan and her family to visit a remote valley in north-west Hawke’s Bay. Over more than 35 years, the Mangahuoanga Stream yielded many land and marine fossils from the Late Cretaceous period, including dinosaurs.

With no formal scientific training, Joan learnt by experience – how to spot fossils, how to extract them from very hard rock, how to identify them and how to use the fossils to put together a picture of ancient New Zealand. She enlisted the help of dinosaur experts abroad (there were none in this country at the time) to carry out identifications and present findings in scientific journals and at conferences. To start with, being a woman with no scientific qualifications was a real drawback, so Joan concentrated on the fossils and their meaning, and gradually, she became accepted by the professional community. Her willingness to communicate her work to children and the general public also made her widely known. Joan ended up having more widespread recognition than most professional scientists.

The timeline below lets you see aspects of Joan's life and work, and how her findings changed scientific thinking. A full timeline transcript is here.

The fossil that started the study of dinosaurs is one of Te Papa’s greatest treasures. In this video Dr Hamish Campbell shows us the very first artifact from the giant lizards.
