The lowlands south of Dunedin (New Zealand), used to be almost impassable wetlands. The local Maoris were incredulous when the first Western explorers of the mid 19th century insisted on making their way tediously directly through it. There were other routes south. The wetlands were a mixture of flax, raupo, sedges, and some small patches… Continue reading The Kai Point Coal Mine – Late Cretaceous vegetation treasure-trove

Eucalyptus (aka ‘gum-tree’) is the quintessential Australian tree. There are about 700 species of them today (depending on who you ask), all of them restricted to Australia, except for a couple that are in New Guinea. They range from cold mountains in Tasmania and Victoria, to tropical lowlands of the Northern Territory.

Cladophlebis – New Zealand’s Mesozoic Weed

The fern Cladophlebis is probably the single-most common plant fossil in the New Zealand Jurassic. It’s present in virtually every plant fossil site of that age (see the Featured Image of this post), so much so that Mildenhall (1974) referred to it as ‘Mesozoic weed’. When New Zealanders talk about ‘fern rock’, it’s a good… Continue reading Cladophlebis – New Zealand’s Mesozoic Weed
