Place your mouse over the flags to hear the text spoken in Welsh and English.

65million years ago the dinosaurs disappeared from the face of the earth after 140 million years of domination.

Was it a gigantic meteor that created a blanket of dust over the world which changed the environment from one friendly to dinosaurs to a hostile one?

Or was it some other cause?

Dinosaurs are fascinating creatures that came in all shapes and sizes.

Walk around our life size models. Meet the Dimetredons - one of the oldest dinosaurs, Tyrannosaurus Rex - the most terrifying, the graceful flying reptiles and very many more.

At the National Showcaves Centre for Wales, we have created One of the World's largest dinosaur parks.
