'DOG BONE' FLINT

Overstrand, Norfolk
 

Flint is made of quartz, or silica, and was formed in soft, limy mud on the floor of the Chalk Sea some 80 million years ago.  Over millions of years the mud containing the flint nodules was compacted to form chalk, which is the bedrock of much of Southern England.

The bizarre shapes of flint nodules are due to flint being formed within and around the burrows of creatures such as sea urchins.  The shape of a flint nodule is therefore often the shape of the animal's burrow.

Some flints on the Norfolk coast have the appearance of bones, hence the name 'Dog bone flint'. This is a particularly good example and quite a fun item.  Two fossil belemnites can also be seen encapsulated by the flint.
