Tropical reefs developed in warm, shallow seas during the Silurian Period, 440 - 410 million years ago. The fossilised remains of one of these reefs are preserved in limestone rocks in parts of England and Wales. These rocks are known as the Wenlock Limestone.

The Wenlock is packed with a huge number of different types of fossils, many of which are very well preserved.
