This year's Lyme Regis Fossil Festival takes place this weekend and explores the theme of rising seas and climate change.
The third annual fossil festival is set in the Jurassic Coast of Lyme Regis, a World Heritage Site . It is the ideal place to explore the issue of climate change as its rocks and fossils give you a glimpse back to the environment 250 million years ago.
The Jurassic Coast fossils reveal how changes in sea level and climate affect the local environment. For example, Lyme Regis was once under the sea and Sidmouth was once a desert.
The event is for the family and there will be plenty of guided walks, talks and workshops to attend. You can even find out about the £22 million coastal protection scheme being built to safeguard the seaside town.
Fossil experts from the Natural History Museum will be there to identify fossil, rock and mineral specimens brought in by the public.
Visitors will also get the first chance to see up close a 190-million-year-old marine reptile ichthyosaur fossil. It was found only four kilometres away near Charmouth and Natural History Museum scientists have been carefully conserving the specimen.
'It's a real thrill to see the ichthyosaur going on show for the first time, so near to where it was found,' says Dr Paul Davis from the Natural History Museum.
'The Jurassic Coast holds a wealth of stories about life millions of years ago and this display highlights how new finds are continually adding to our understanding of the fossils already looked after by the Museum.'
Students will take part in the summit and explore whether these past environmental changes are different from what is happening now and whether we can do anything about the changes.
Rising Seas Lyme Regis Fossil Festival 2007 is on 4 -6 May .
