It affected many groups of organisms in many different ... The story of these dazzling and shifting dunes began 280 million years ago when the Permian Sea covered the area and gypsum settled on the seafloor. A common mineral found all over the world, gypsum is rarely found in sand form, making the 275-square-mile dunefield a profoundly unique natural wonder. Ocean acidification, driven by an overload of CO2 in our seas, is literally causing a sea change, threatening the chemical balance of ocean and coastal waters worldwide. Ocean acidification is a severe threat to shellfish, corals and other marine life because corrosive water can destroy their protective shells and skeletons, puttBrachiopod Fossils. The most common seashells at the beach today are bivalves: clams, oysters, scallops, and mussels.
