valley of the whales

Can you imagine being under the sea?

 

The cliffs exposed in this section of the Awamoko valley (known as the Valley of the Whales) showcase a thick sequence of sediments. These sediments accumulated on the seafloor 23 -29 million years ago. At that time much of Te Riu-a-Māui/Zealandia, the continent New Zealand is part of, was still submerged beneath a warm shallow sea.


The Otekaike Limestone can be seen in the upper layers of these cliffs. The limestone is grey in colour where it has been weathered. It is creamy in colour where recent rock falls expose fresh surfaces. The older Kokoamu Greensand outcrops towards the base of the cliffs. The green colour is due to the mineral glauconite. Glauconite forms in some marine environments where there is little to no sediment input.

Ancient marine life preserved

 

The limestone and greensand exposed in the cliffs here, once formed a continuous sheet across the width of the valley. The Awamoko Stream has eroded down through these to form this valley. The sediments in the cliffs expose a cross section through time. The fossils preserved within them give us a glimpse back at the past life that once occupied our ancient seas. Such fossils include the teeth of an extinct white shark, the partial skeleton of the extinct ‘giant’ penguin Kairuku and extinct baleen whale skulls.

To learn more about these ancient creatures visit the Vanished World Centre in Duntroon. At Vanished World you can view casts and original fossils.

Fast facts

 

  • Fossils from the marine sediments here are between 23 - 29 million years old.

  • The lines you see in the cliff are original sea beds from when layers of sediment were deposited.

  • This site is part of the area known as Maerewhenua to Kāi Tahu Whānui and was once treasured for its abundance of mahika kai.
