A series of walks around the 50-acre site, on a hillside above the old mining town of Wirksworth, reinforces this. Explanatory boards point out that although the area covered by the centre was once a series of stone quarries, 330 million years before that - long before the dinosaurs roamed around here - it was the floor of a giant tropical lagoon.
Once you realise that you are walking on a former sea bed, your eyes are alerted to the abundant fossils - teeth of the sharks that once swam there, sea lilies (crinoids) that lived in the shelter of the reefs, molluscs, brachiopods (shelled creatures), and corals. The larger fossils are on the faces of the carboniferous limestone. Smaller ones are found on many of the pieces of stone lying on the ground. Visitors can pick these up and take them home.
Inside the Centre you can see the myriad of uses stone is put to - including toothpaste, thermoplastics, food processing and fine china. Children can have a go at casting fossils in dental plaster, panning for gemstones, and fossil-rubbing using tracing paper and large casts of the fossils.
Amanda Spencer took her children Jake, three, and Gemma, 10, and their cousin Lucy, four.
Amanda: This place appealed to all of us. The little ones were entranced by all the colours, textures and shapes of the rocks on show.
The smaller children love gem-panning. For 65p you buy a scoop of sand mixed with tiny gems. Then you go to the special pool, where you are given a pan which you use to wash away the sand very carefuly until all the gems appear. And you can name them with the help of identification boards, or a little book on sale in the shop.
We've been here several times - the children never get bored here. When the weather is too bad to go round the trail or to go fossil-hunting outside, there is always something new to see in the Story of Stone exhibition. It's one of the best preserved carboniferous fossil reefs in the country; we call it Derbyshire-on-Sea.
Jake: I like gem-panning. There are all sorts of little precious stones buried in sand. You sometimes get wet, but it's worth it. You can take the gems home and make patterns with them. I also like the sound of the explosions in the surrounding quarries.
Lucy: I like all the slopes, and the fossils in the rocks; also the views over the hills and old quarries. I managed to find some fossils in the big rocks and also brought home some smaller rocks with fossils in them that I found on the ground. They show tiny creatures, which are really ancient.
I also like the shop. There are all sorts of rocks on sale. They are all different colours and shapes and sizes and I like feeling them. They also come from countries all over the world, which is interesting. The exhibition is great fun. It shows all the things that can be made from stone.
Gemma: There is masses to see on the walks around the old quarries. You can go round several times and still see different things. I find it fascinating that sharks once swam here. You can see the evidence. I collect different rocks, so the shop was especially interesting.
The Story of Stone exhibition is quite large and detailed, but very clear. Some of the sections were a bit difficult for me, but I liked the display of the famous buildings, such as cathedrals, universities and airports, that have been built using stone.
It was also interesting seeing how much we depend on stone. I still can't believe that each of us uses at least five tonnes of stone a year, and that there is rock in the clothes we wear, as well as in things like steel, rubber and medicines. I also liked the quiz, which had all sorts of fun questions.
