The Grotto Beach Formation is a geologic formation in the Bahamas. It preserves fossils dating back to the Middle to Late Pleistocene period. [1]
The Bahamas, known officially as The Commonwealth of The Bahamas, is a sovereign country within the Lucayan Archipelago of the West Indies in the Atlantic. It takes up 97% of the Lucayan Archipelago's land area and is home to 88% of the archipelago's population. The archipelagic state consists of more than 700 islands, cays, and islets in the Atlantic Ocean, and is located north of Cuba and northwest of the island of Hispaniola and the Turks and Caicos Islands, southeast of the American state of Florida, and east of the Florida Keys. The capital is Nassau on the island of New Providence. The Royal Bahamas Defence Force describes The Bahamas' territory as encompassing 470,000 km2 (180,000 sq mi) of ocean space.
An atoll, sometimes known as a coral atoll, is a ring-shaped coral reef, including a coral rim that encircles a lagoon partially or completely. There may be coral islands or cays on the rim. Atolls are located in warm tropical or subtropical oceans and seas where corals can grow. Most of the approximately 440 atolls in the world are in the Pacific Ocean.
A raised beach, coastal terrace, or perched coastline is a relatively flat, horizontal or gently inclined surface of marine origin, mostly an old abrasion platform which has been lifted out of the sphere of wave activity. Thus, it lies above or under the current sea level, depending on the time of its formation. It is bounded by a steeper ascending slope on the landward side and a steeper descending slope on the seaward side. Due to its generally flat shape it is often used for anthropogenic structures such as settlements and infrastructure.
A cay, also spelled caye or key, is a small, low-elevation, sandy island on the surface of a coral reef. Cays occur in tropical environments throughout the Pacific, Atlantic, and Indian Oceans, including in the Caribbean and on the Great Barrier Reef and Belize Barrier Reef.
San Salvador Island is an island and district of the Bahamas. It is widely believed that during Christopher Columbus's first expedition to the New World, this island was the first land he sighted and visited on 12 October 1492. He named it San Salvador after Christ the Saviour. Columbus's records indicate that the native Lucayan inhabitants of the territory, who called their island Guanahani, were "sweet and gentle".
The Bimini Road, sometimes called the Bimini Wall, is an underwater rock formation near North Bimini island in the Bahamas. The Road consists of a 0.8 km (0.50 mi)-long northeast-southwest linear feature composed of roughly rectangular to subrectangular limestone blocks. Various claims have been made for this feature being either a wall, road, pier, breakwater, or other man-made structure. However, credible evidence or arguments are lacking for such an origin.
In geology, a terrace is a step-like landform. A terrace consists of a flat or gently sloping geomorphic surface, called a tread, that is typically bounded on one side by a steeper ascending slope, which is called a "riser" or "scarp". The tread and the steeper descending slope together constitute the terrace. Terraces can also consist of a tread bounded on all sides by a descending riser or scarp. A narrow terrace is often called a bench.
Marine Isotope Stage 11 or MIS 11 is a Marine Isotope Stage in the geologic temperature record, covering the interglacial period between 424,000 and 374,000 years ago. It corresponds to the Hoxnian Stage in Britain.

Paleontology in Wisconsin refers to paleontological research occurring within or conducted by people from the U.S. state of Wisconsin. The state has fossils from the Precambrian, much of the Paleozoic, and the later part of the Cenozoic. Most of the Paleozoic rocks are marine in origin. Because of the thick blanket of Pleistocene glacial sediment that covers the rock strata in most of the state, Wisconsin’s fossil record is relatively sparse. In spite of this, certain Wisconsin paleontological occurrences provide exceptional insights concerning the history and diversity of life on Earth.

The Lucayan Formation is a geologic formation in the Bahamas. It preserves fossils dating back to the Early Pleistocene period.
