Petrified Trees on Wave-cut Platform

OTAGO - Curio Bay the Catlins, New Zealand
A famous Jurassic fossil forest is exposed on the beach.

 

The fossil forest is lying on a wave-cut platform which has been eroded into sandstones that were laid down by a river or flood. The logs and tree stumps on top of the sandstone were once growing in a swampy area on the river flats. It is thought that they were buried by ancient volcanic mudflows that flooded over the area from a nearby volcano. The fossil plant species (ferns, cycads and conifers) show that the climate at the time was semi-tropical. This was before the arrival of flowering plants.
