Ancient termite poo reveals 120 million-year -old secrets of Australia’s polar forests
Imagine a lush forest with tree-ferns, their trunks capped by ribbon-like fronds. Conifers tower overhead, bearing triangular leaves almost sharp enough to pierce skin. Flowering plants are both small and rare.
You’re standing in what is now Victoria, Australia, about 127 million years ago during the Early Cretaceous Period. Slightly to your south, a massive river – more than a kilometre wide – separates you from Tasmania. This river flows along the valley forming between Australia and Antarctica as the two continents begin to split apart.
During the Early Cretaceous, southeastern Australia was some of the closest land to the South Pole. Here, the night lasted for three months in winter, contrasting with three months of daytime in summer. Despite this extreme day-night cycle, various kinds of dinosaurs still thrived here, as did flies, wasps and dragonflies.
And, as our recently published research in Palaeogeography, Palaeoclimatology, Palaeoecology reveals, termites also chewed through the decaying wood of fallen trees. This is the first record of termites living in a........
