Perhaps the most surprising thing about Nothofagus leaf fossils in New Zealand is – not finding them. Nothofagus is another name for the southern beech trees that form forests in New Zealand, as well as Australia, Patagonia, New Caledonia and New Guinea. As a group, the beeches are… Read more

Interdistributary drifters – a Miocene bay in New Zealand
One of the more evocative Miocene fossils you might pick up near Bannockburn, New Zealand, are she-oak ‘cones’ (see the featured image). The Latin name is Casuarina (but see ‘Technical Details’, below). This is a plant that no-longer grows naturally in New Zealand, but is a tree in… Read more
Podozamites – a multi-veined conifer in New Zealand’s Jurassic
Most conifer leaves have just one vein, whether they be the needles of pines, or the much broader leaves of some tropical conifers. This limits their size and shape (they mostly stay small and can’t do fancy stuff like many flowering plant leaves). Just two… Read more
Blue Lake, St Bathans – the most biodiverse Miocene fossil plant locality
The biodiversity of Blue Lake, at St Bathans, New Zealand, is precisely zero. It is an artificial lake partly filling a hole blasted out in the search for gold in the 19th century. The hole is directly in front of one of St Bathan’s and New… Read more
Giant Pea Pod fossils in New Zealand’s Miocene
Pea pod fossils in New Zealand were first found by Aline Holden, a pioneer of New Zealand plant fossil research. She found the first ones at Bannockburn in 1981, while working on her PhD, and then found more in the Nevis Valley. In 1987, my… Read more
Hoop Pine fossils – dry rainforest in New Zealand’s Miocene
In a little patch of shale, continually flaking onto the road near Bannockburn (central South Island, New Zealand), there are the unmistakable fossils like Australian ‘hoop pine’ shoots. Hoop pines are members of the tree family which includes ‘monkey puzzles’, ‘bunyas’ and the ‘Norfolk Island Pines’. The… Read more
New Zealand: The Jurassic fossil forest at Curio Bay
If you make your way down to almost the bottom of New Zealand’s South Island, you can walk among the stumps of a petrified Jurassic forest (that’s about 170 million years old). It’s a gem of New Zealand’s fossil plant history, and because of its complete preservation… Read more
Five Degrees of Global Warming – The Leaf Fossils of Kakahu, New Zealand
Sometime in the 1980s my Prof, ‘JDC’ (Doug Campbell of the Otago University), showed me a box of spectacular leaf fossils that had been collected from Kakahu by Graeme Mason while “out rabbiting”. Kakahu is a farming district in the hills, a few kilometres out… Read more
Where was the Murihiku in the Jurassic?
A few years ago I used to teach American classes that came to the University of Queensland. One evening my Stanford class had just arrived and I wandered over to their college accommodation to say Hello. I came across an odd sight – a knot… Read more
Globalisation in the Jurassic – the fossil fern Coniopteris in New Zealand
One of the plant fossils that turns up in New Zealand’s Jurassic rocks is a delicate-looking fern frond called Coniopteris (Arber, 1917; Edwards, 1934; see featured image). The well-known Jurassic fossil forest at Curio Bay (Pole 1999) would have had Coniopteris growing in it. And,… Read more
