Wren's Nest National Nature Reserve

Over 400 million years ago, the area where Dudley now stands was covered by coral reefs and tropical seas providing an environment for the famous fossils we find there today. Over 700 types of fossil are known to have come from Wren's Nest. 186 of which were first discovered and described here and 86 are found nowhere else on Earth.

Wren's Nest National Nature Reserve is a classic geological site of exceptional importance.

It is one of the most notable geological locations in the British Isles and visited and studied by geologists from all over the world.  

These pages will provide you with information on the site and the activities that take place here.
