100 million years ago, dead sea creatures fell to the seafloor and were compressed by the pressure of the water above it into limestone. This is the same limestone you could find in Derbyshire or other limestone quarries. This process was discovered by Alan Bolton, a chemistry teacher in 1873 when he replicated the conditions in his science lab with a high pressure chamber. Hope this helps
