North America’s Great Lakes region was once the bed of an ancient sea. Fossils abound if one knows where and how to look. Paleozoic fossils of many periods regularly wash up on the shores of Lake Michigan’s Left Coast.
Like this skull of an amphibian, many Great Lakes fossils from the Permian Period (280–235 years ago) have turned into limestone. Though they are eroded and sometimes crushed, skulls are often recognizable.
