“How old is it?” is one of the first questions you’ll probably ask when you see an interesting rock or fossil. It’s certainly one of the first things that a geologist wants to know. As you’ll ...
Dinosaurs used to live in New Zealand. We know this because their fossils have been found in a few places. The fossils of a number of different dinosaurs were found at the Mangahouanga Stream, in ...
The study of fossils, combined with accurate dating, gives us a detailed picture of climate and environment changes in New Zealand over the last few million years. Rights: The University of ...
In this activity, students date fossils from one site by matching them to fossils already dated somewhere else. They use real data from Mangahouanga, made famous by paleontologist Joan Wiffen. By ...
In this activity, students use different pieces of a jigsaw to work through a process of observation, discussion, collaboration and deduction to determine what the picture shows. The activity is ...
Scientists have a variety of methods to use when they try to date a rock or a rock layer. Scientists choose the method that best suits their material – they might use relative or absolute dating ...
By comparing some features of fossilised plants with the same features of plants living today, scientists hope to be able to learn more about the effect of changing carbon dioxide (CO2) levels in ...
The Planet Four online citizen science project is designed to assist planetary scientists to identify and measure features on the surface of Mars that don’t exist on Earth. Help is needed to ...
About 14,000 earthquakes are recorded in and around Aotearoa New Zealand every year. Canterbury’s 7.1 and Kaikōura's 7.8 magnitude earthquakes and subsequent aftershocks show the constant threat ...
In this recorded professional learning session, Lyn Rogers and guest Aliki Weststrate from GNS Science explore some of the science involved in building our understandings of natural hazards ...
Why is the sky blue? Why do stars twinkle? Why did the apple fall to the ground? What happens if I hit this rock with another rock? As humans, we’re curious, and throughout history, we’ve ...
Joan Wiffen and colleagues were famous for finding fossils at Mangahouanga Stream, in north-west Hawke’s Bay. Dr James Crampton, paleontologist at GNS Science, outlines some of the marine ...
Dr James Crampton, paleontologist at GNS Science, explains how relative dating was used to determine that dinosaur and other fossils found in north-west Hawke’s Bay were from the Cretaceous ...
Watch this animated video and find out more on how sedimentary rock near Whanganui records 50 cycles of sea level change, each lasting up to 100,000 years. Rocks were formed during warm ...
This timeline lets you see aspects of Joan's life and work, and how these fit into a wider science picture of paleontology. A full transcript is underneath.
Historical artefacts like moa bones can be dated using a technique that measures the activity of the radioisotope carbon-14 still present in the sample. By comparing this with a modern standard ...
This timeline lets you see aspects of Athol's life and work, and how these fit into a wider science picture of radiocarbon dating. A full transcript is underneath.
