These fossils are usually formed from the skeletal fragments of marine organisms. It is truly amazing to think; what were once living creatures have been preserved for millions of years within this natural stone and can now feature within your very own home. Just imagine this unique aesthetic on the floor of your kitchen, bathroom or conservatory?!
