Aztecodus is an extinct genus of Chondrichthyian from the Devonian period. [1] It is named for middle to late Devonian-aged Aztec Siltstone of southern Victoria Land, Antarctica which produces this genus. It currently contains a singular species, A. harmsenae. It is named for sedimentologist Dr. Fraka Harmsen. It has unique teeth which are broad with widely divergent cusps separated by a crenulated cutting edge. [2] Anareodus statei may be a junior synonym to this genus and species. [3]

The Ellsworth Mountains are the highest mountain ranges in Antarctica, forming a 350 km (217 mi) long and 48 km (30 mi) wide chain of mountains in a north to south configuration on the western margin of the Ronne Ice Shelf in Marie Byrd Land. They are bisected by Minnesota Glacier to form the Sentinel Range to the north and the Heritage Range to the south. The former is by far the higher and more spectacular with Mount Vinson constituting the highest point on the continent. The mountains are located within the Chilean Antarctic territorial claim but outside of the Argentinian and British ones.

<span class="mw-page-title-main">Alfisol</span> Soil type

Alfisols are a soil order in USDA soil taxonomy. Alfisols form in semi-arid to humid areas, typically under a hardwood forest cover. They have a clay-enriched subsoil and relatively high native fertility. "Alf" refers to aluminium (Al) and iron (Fe). Because of their productivity and abundance, Alfisols represent one of the more important soil orders for food and fiber production. They are widely used both in agriculture and forestry, and are generally easier to keep fertile than other humid-climate soils, though those in Australia and Africa are still very deficient in nitrogen and available phosphorus. Those in monsoonal tropical regions, however, have a tendency to acidify when heavily cultivated, especially when nitrogenous fertilizers are used.

<i>Groenlandaspis</i> Genus of fishes (fossil)

Groenlandaspis is an extinct genus of arthrodire from the Late Devonian. Fossils of the different species are found in late Devonian strata in all continents except eastern Asia. The generic name commemorates the fact that the first specimens of the type species were found in Greenland.

<i>Holoptychius</i> Extinct genus of fishes

Holoptychius is an extinct genus of porolepiform lobe-finned fish from the Middle Devonian to Carboniferous (Mississippian) periods. It is known from fossils worldwide. The genus was first described by Louis Agassiz in 1839.

<i>Lunaspis</i> Extinct genus of placoderm fish

Lunaspis is an extinct genus of armor-plated petalichthyid placoderm fish that lived in shallow marine environments of the Early Devonian period, from approximately 409.1 to 402.5 million year ago. Fossils have been found in Germany, China and Australia. There are three different identified species of within the genus Lunaspis: L. broilii, L. heroldi, and L. prumiensis.

<i>Meteoraspis</i>

Meteoraspis is an extinct genus of ptychopariid trilobites of the family Tricrepicephalidae. The various species lived from 501 to 497 million years ago during the Dresbachian faunal stage of the late Cambrian Period. Fossils of Meteoraspis are characteristic of Late Cambrian strata in North America, though they are found in Late Cambrian strata elsewhere in the world, such as M. nevensis from Victoria Land, Antarctica.

Aztec Mountain is a small pyramidal mountain over 2,000 metres (6,600 ft) high, just southwest of Maya Mountain and west of Beacon Valley in Victoria Land. It was so named by the New Zealand Geological Survey Antarctic Expedition (1958–59) because its shape resembles the pyramidal ceremonial platforms used by the Aztec and Maya civilizations.

<i>Phyllolepis</i>

Phyllolepis is the type genus of Phyllolepida, an extinct taxon of arthrodire placoderm fish from the middle to late Devonian. The species of Phyllolepis, themselves, are restricted to the Famennian-aged freshwater strata of the Late Devonian, around 360 million years ago. Fossils of this genus have been found primarily in Europe and North America. The end of the Devonian saw them disappear in a mass extinction.

<span class="mw-page-title-main">Beacon Supergroup</span>

The Beacon Supergroup is a geological formation exposed in Antarctica and deposited from the Devonian to the Triassic. The unit was originally described as either a formation or sandstone, and upgraded to group and supergroup as time passed. It contains a sandy member known as the Beacon Heights Orthoquartzite.

<i>Neophlyctaenius</i>

Neophlyctaenius is an extinct genus of placoderm fish, which lived during the Late Devonian period of North America.

Mount Weller is a peak (2,420 m) rising above the west side of Beacon Valley, 4 nautical miles (7 km) southwest of Pyramid Mountain, in Quartermain Mountains, Victoria Land, Antarctica. It is also 90 miles (140 km) due west of McMurdo Station. The name appears to be first used on a 1961 New Zealand Lands and Survey Department map compiled from New Zealand field surveys, 1957–60, and U.S. Navy aerial photographs of that period. Presumably named after William J. Weller, Royal Navy, a seaman of the ship RSS Discovery. In November 1903, Weller and Thomas Kennar accompanied Hartley T. Ferrar in the first geological reconnaissance of Quartermain Mountains.

Fault Bluff is a 2,320 metres (7,600 ft) high rock bluff located about 9 nautical miles (17 km) northeast of Mount Longhurst in the Cook Mountains of Antarctica. The rock bluff was visited in the 1957–58 season by the Darwin Glacier Party of the Commonwealth Trans-Antarctic Expedition, 1956–58. They originated the name which presumably refers to a geological fault at the bluff.

Maya Mountain is a small pyramidal mountain, about 2,000 metres (6,600 ft) high, between Aztec Mountain and Pyramid Mountain, just south of Taylor Glacier in Victoria Land, Antarctica. It was so named by the New Zealand Geological Survey Antarctic Expedition (1958–59) because its shape resembles the pyramidal ceremonial platforms used by the Maya civilization.

Mount Ritchie is a mountain rising over 1600 m in the southeast part of Warren Range, Antarctica. The feature is 5.6 km (3 nmi) northeast of Wise Peak on the west side of Deception Glacier. Named by the Victoria University of Wellington Antarctic Expedition (VUWAE), 1970–71, after Alex Ritchie, curator of fossils at the Australian Museum, Sydney, a member of the VUWAE party that discovered important sites of fossil fish in this Skelton Neve area.

The Lashly Mountains are a small group of mountains, the most prominent at 2,550 metres (8,370 ft) being Mount Crean, standing south of the head of Taylor Glacier and west of Lashly Glacier, in Victoria Land, Antarctica.

<i>Antarctilamna</i> Extinct genus of Devonian shark

Antarctilamna is an extinct genus of Devonian cartilaginous fish originally exemplified by Antarctilamna prisca from South Eastern Australia and Antarctica. The latest occurring described species is Antarctilamna ultima from the Waterloo Farm lagerstätte in South Africa. Antarctilamna has robust ctenacanthid-like spines which lack a deep insertion area, and are borne in front of the first dorsal fin; in addition to distinctive diplodont teeth with small intermediate cusps. Antarctilamna-like spines, known from the Bunga Beds locality in Australia have been ascribed to A. prisca.

The Bokkeveld Group is the second of the three main subdivisions of the Cape Supergroup in South Africa. It overlies the Table Mountain Group and underlies the Witteberg Group. The Bokkeveld Group rocks are considered to range between Lower Devonian (Lochkovian) to Middle Devonian (Givetian) in age.

<i>Lebachacanthus</i> Extinct genus of cartilaginous fishes

Lebachacanthus is a genus of extinct xenacanth cartilaginous fish known from the late Carboniferous-Early Permian of Europe. During the late Paleozoic, xenacanths were the apex predators of freshwater ecosystems, preying on small amphibians.
