Foulden Maar: fossils or food?
This Connected article explains how an ancient lake, Foulden Maar was formed by a volcanic eruption 23 million years ago and is very fossil rich. In 2019 it came to the public’s attention when a mining company, which owned the land, had been granted permission to mine there. The scientific community started a campaign against this proposal.
Connected article: Foulden Maar: fossils or food?
An article in the 2020 level 4 Connected journal ‘Feeling the Heat’ published by the Ministry of Education, New Zealand.
Use this article to learn about:
the creation of Foulden Maar
how fossils form, and what is it that makes the fossils at Foulden Maar so special
why mine at Foulden Maar – the economic value of diatomite
who are involved in the decisions about the future of the maar (the stakeholders)
what could be the future for Foulden Maar.
This article prompts critical thinking and ends with a call to social action.
Key nature of science ideas
Use this article to help explain to your students how scientists:
look for reliable evidence
consider what other scientists have discovered when making a decision about a situation
work within a cultural context where science influences and is also influenced by societal responses.
Galaxiid fossil
Galaxias effusus holotype fossil from Foulden Maar. This is the oldest galaxiid fish in the world.
Key science ideas
Some of the key science science ideas and concepts covered include:
processes that cause the Earth to change over time
the processes that gradually change sediments into rocks also help form fossils
fossils are the remains of organisms, or traces of their activities preserved in some manner
fossils can help us learn about living organism that were on Earth before there were people
some fossil materials have an economic value as they can be used to make products.

2020 Connected Level 4: Feeling the Heat
The cover of the 2020 level 4 Connected journal ‘Feeling the Heat’ published by the Ministry of Education, New Zealand. This issue includes the articles Pā Tūwatawata and the New Zealand Wars, Fostering felines, Foulden Maar: fossils or food? and Wildfires.
There are three learning activities that support the exploring science aspects of the New Zealand Curriculum:
Fossils of food? – students take on the roles of various stakeholders with an extension idea on taking action.
Buried treasure – understanding and learning from fossils, ending with creating a job description for a Foulden Maar palaeontologist.
Geopark – students explore what a geopark is and design their own, and then use Minecraft to build a model.

The National Paleontological Collection includes a large number of type and figured specimens, and comprehensive stratigraphic and geological collections of fossil taxa from New Zealand and its surrounding area (including Antarctica).
A geopark is a defined area of international geological significance that tells the story of how the geology and landscape have shaped the lives of its inhabitants, be they people, animals or plants. It is a new UNESCO designation. The Waitaki Whitestone Geopark in the South Island is seeking to be the first designated geopark in Oceania.
This 2022 RNZ (Radio New Zealand) story about University of Otago scientist Daphne Lee’s new book Fossil Treasures of Foulden Maar provides a glimpse into this paleontological site, include is an interview and lots of beautiful images.
UPDATE: In January 2023 Dunedin City Council announced that it had reached an agreement buy the Foulden Maar mining site. Read this RadioNZ news story.
