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
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
Palissya – mysterious cone of New Zealand’s Jurassic forests
In the early 1980s when I was working on the Jurassic fossil forest of Curio Bay, near the bottom end of New Zealand’s South Island, it seemed clear that two main types of tree formed the forest canopy. There were two types of conifer foliage fossil around Curio… Read more
Cabin Fever and Paleocene leaf fossils in the Haast
Easter, 1971. The family is holed-up in a tiny home-made caravan at Cole Creek, in New Zealand’s forest-clad South Westland just north of Haast. It’s bucketing-down. We’re there because our Dad has an infatuation with finding the missing backpack of a murdered woman, Jennifer Beard.… Read more
The Highlands Motorsport Park ‘Jurassic Forest Safari’
Growing up in Alexandra it inconceivable that Cromwell might somehow overtake Alex. Alexandra was The Hub. Cromwell was the little place you passed through on the way to the little villages of Queenstown or Wanaka, where you holidayed. But things have happened in Cromwell, and… Read more
