A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the fossil record.
The Mariana Trench is an oceanic trench located in the western Pacific Ocean, about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width. The maximum known depth is 10,984 ± 25 metres at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep. If Mount Everest were placed into the trench at this point, its peak would still be underwater by more than 2 kilometres (1.2 mi).
South Georgia and the South Sandwich Islands (SGSSI) is a British Overseas Territory in the southern Atlantic Ocean. It is a remote and inhospitable collection of islands, consisting of South Georgia and a chain of smaller islands known as the South Sandwich Islands. South Georgia is 165 kilometres (103 mi) long and 35 kilometres (22 mi) wide and is by far the largest island in the territory. The South Sandwich Islands lie about 700 kilometres (430 mi) southeast of South Georgia. The territory's total land area is 3,903 km2 (1,507 sq mi). The Falkland Islands are about 1,300 kilometres (810 mi) west from its nearest point.
The Spratly Islands are a disputed archipelago in the South China Sea. Composed of islands, islets, cays, and more than 100 reefs, sometimes grouped in submerged old atolls, the archipelago lies off the coasts of the Philippines, Malaysia, and southern Vietnam. Named after the 19th-century British whaling captain Richard Spratly who sighted Spratly Island in 1843, the islands contain less than 2 km2 of naturally occurring land area, which is spread over an area of more than 425,000 km2 (164,000 sq mi).
Stromatolites or stromatoliths are layered sedimentary formations (microbialite) that are created mainly by photosynthetic microorganisms such as cyanobacteria, sulfate-reducing bacteria, and Pseudomonadota. These microorganisms produce adhesive compounds that cement sand and other rocky materials to form mineral "microbial mats". In turn, these mats build up layer by layer, growing gradually over time. A stromatolite may grow to a meter or more. Although they are rare today, fossilized stromatolites provide records of ancient life on Earth.
The Belcher Islands are an archipelago in the southeast part of Hudson Bay near the centre of the Nastapoka arc. The Belcher Islands are spread out over almost 3,000 km2 (1,200 sq mi). Administratively, they belong to the Qikiqtaaluk Region of Nunavut, Canada. The hamlet of Sanikiluaq is on the north coast of Flaherty Island and is the southernmost in Nunavut. Along with Flaherty Island, the other large islands are Kugong Island, Tukarak Island, and Innetalling Island. Other main islands in the 1,500–island archipelago are Moore Island, Wiegand Island, Split Island, Snape Island and Mavor Island, while island groups include the Sleeper Islands, King George Islands, and Bakers Dozen Islands.
Cyanobacteria, also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name cyanobacteria refers to their color, which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they are not usually scientifically classified as algae. They appear to have originated in a freshwater or terrestrial environment. Sericytochromatia, the proposed name of the paraphyletic and most basal group, is the ancestor of both the non-photosynthetic group Melainabacteria and the photosynthetic cyanobacteria, also called Oxyphotobacteria.
Ronald Lee Ermey was an American actor and U.S. Marine drill instructor. He achieved fame for his role as Gunnery Sergeant Hartman in the 1987 film Full Metal Jacket, which earned him a Golden Globe nomination for Best Supporting Actor. Ermey was also a United States Marine Corps staff sergeant and an honorary gunnery sergeant.
Shark Bay is a World Heritage Site in the Gascoyne region of Western Australia. The 23,000-square-kilometre (8,900 sq mi) area is located approximately 800 kilometres (500 mi) north of Perth, on the westernmost point of the Australian continent. UNESCO's official listing of Shark Bay as a World Heritage Site reads:
Marble Bar is a town and rock formation in the Pilbara region of north-western Western Australia. Its extremely hot climate, with a mean maximum temperature second only to Wyndham, Western Australia has resulted in the town being well known for its hot weather.
Jeju Island is South Korea's largest island, covering an area of 1,833.2 km2 (707.8 sq mi), which is 1.83 percent of the total area of the country. It is also the most populous island in South Korea; at the end of September 2020, the total resident registration population of Jeju Province is 672,948, of which 4,000 reside on outlying islands such as the Chuja Islands and Udo Island. The total area of the Jeju Special Self-Governing Province is 1,849 km2 (714 sq mi).
Cervantes is a town in Western Australia located off of Indian Ocean Drive about 198 kilometres (123 mi) north-north-west of the state capital, Perth in the Shire of Dandaragan local government area. At the 2016 census, Cervantes had a population of 527. The town was named after a ship that was wrecked nearby. The ship, in turn, was named after Miguel de Cervantes, author of Don Quixote.
Algal mats are one of many types of microbial mat that forms on the surface of water or rocks. They are typically composed of blue-green cyanobacteria and sediments. Formation occurs when alternating layers of blue-green bacteria and sediments are deposited or grow in place, creating dark-laminated layers. Stromatolites are prime examples of algal mats. Algal mats played an important role in the Great Oxidation Event on Earth some 2.3 billion years ago. Algal mats can become a significant ecological problem, if the mats grow so expansive or thick as to disrupt the other underwater marine life by blocking the sunlight or producing toxic chemicals.
The Hamelin Pool Marine Nature Reserve is a protected marine nature reserve located in the UNESCO World Heritage–listed Shark Bay in the Gascoyne region of Western Australia. The 127,000-hectare (310,000-acre) nature reserve boasts the most diverse and abundant examples of living marine stromatolites in the world, monuments to life on Earth over 3,500 million years BP.

The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the world ocean, generally taken to be south of 60° S latitude and encircling Antarctica. With a size of 20,327,000 km2 (7,848,000 sq mi), it is regarded as the second-smallest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian oceans but larger than the Arctic Ocean. Since the 1980s, the Southern Ocean has been subject to rapid climate change, which has led to changes in the marine ecosystem.
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.
