A FIERCE prehistoric swamp monster will confront young time-travellers exploring life from nearly 300 million years ago.

Eryops, affectionately known as Swampy, was a 1.5m long flesh-eating amphibian which lurked in the depths of Weardale, County Durham, during the Carboniferous period.

At the time it existed, Weardale was covered by a dense tropical forest which was home to a variety of large amphibians, reptiles and insects.

Visitors to the Killhope Lead Mining Centre this weekend will be able to visit the distant past through an adventure brought to life by the national children's geological club, Rockwatch and Blue Circle Cement works, in Weardale.

Fossilised remains of prehistoric creatures, including the skull of an eryops, will be displayed at the centre, and youngsters can enjoy activities such as making a 3D Carboniferous forest and riding on a trilobite.

The event runs from 10am to 4pm today and tomorrow.

It is free after paying entry to the centre which is £3.40 for adults and £1.70 for children. A family ticket is £8.50. For more information, contact 0870 036 1000.
