The Moeraki Boulders are a group of perhaps 30 spherical boulders on Koekohe Beach on the south east coast of the South Island of New Zealand.
They originally formed in ancient sea floor sediments around 60 million years ago.
The larger boulders are around 2 metres in diameter.
The boulders are riddled with large cracks called “septaria” which radiate outwards from a hollow core.
The cracks are filled with layers of brown or yellow calcite.
This boulder is beginning to disintegrate, revealing its hollow core.

It appears that someone has fashioned this very lifelike looking cormorant on a boulder for the benefit of tourists.
I am reminded of elephants and tortoises.
