The reason behind this drastic climate shift isthe former location of the Great Lakes region, which roughly 400 million years ago used to be on the equator. This era, called the Paleozoic, was a time when corals, mollusks, trilobites, and brachiopods inhabited a warm and fertile ocean. Michigan is a hotspot for fossils: What to know, where to look From the Permian period (299-252 million years ago) to the end of the Neogene (23-2.6 million years ago), erosion was occurring and no sediments were deposited locally, leaving behind no rocks or fossils.
