Portland limestone was formed in a shallow, warm, sub-tropical sea on the continental shelf of what is now western Europe. Limestones are mostly made of calcium carbonate. This comes originally from the bodies of many small organisms which build their shells or framework out of CaCO 3 crystals. An example is the type of protist called ...
