The Atane Formation is a geologic formation in Greenland. It preserves fossil insects of Elytrulum multipunctatum , [1] dating back to the Albian to Coniacian stages of the Cretaceous period. [2]
The carbonaceous mudstones, sandstones and coal seams are interpreted as freshwater lake or swamp deposits representing the vertical aggradation of a subaerial to shallow, limnic floodplain to upper delta plain. There are no indications –neither palynological evidence nor the presence of pyrite– to suggest marine or brackish-water conditions. [2]
Nils Adolf Erik Nordenskiöld was a Finland-Swedish aristocrat, geologist, mineralogist and Arctic explorer. He was a member of the noble Nordenskiöld family of scientists and held the title of a friherre (baron).
Alfred Gabriel Nathorst was a Swedish Arctic explorer, geologist, and palaeobotanist.

Paul or Poul Hansen Egede was a Dano-Norwegian theologian, missionary, and scholar who was principally concerned with the Lutheran mission among the Kalaallit people in Greenland that had been established by his father, Hans, in 1721.
Garðar was the seat of the bishop in the Norse settlements in Greenland. It is a Latin Catholic titular see, and was the first Catholic diocese established in the Americas.
Gustav Frederik Holm was a Danish naval officer and Arctic explorer born in Copenhagen.
Tyge Wittrock Böcher was a Danish botanist, evolutionary biologist, plant ecologist and phytogeographer.
Carl Emil Hansen Ostenfeld was a Danish systematic botanist. He graduated from the University of Copenhagen under professor Eugenius Warming. He was a keeper at the Botanical Museum 1900–1918, when he became professor of botany at the Royal Veterinary and Agricultural University. In 1923, by the early retirement of Raunkiær's, Ostenfeld became professor of botany at the University of Copenhagen and director of the Copenhagen Botanical Garden, both positions held until his death in 1931. He was a member of the Royal Danish Academy of Sciences and Letters and served on the board of directors of the Carlsberg Foundation.
Morten Pedersen Porsild was a Danish botanist who lived and worked most of his adult life in Greenland. He participated in expeditions to Greenland in 1898 and 1902, together with the physiologist August Krogh. In 1906, he founded the Arctic Station in Qeqertarsuaq, West Greenland, since 1956 part of the University of Copenhagen. He got support from famous polar researchers like Knud Rasmussen, Mylius-Erichsen and Fridtjof Nansen. A private person donated the building and running cost were put directly on the Danish state budget. Morten Porsild managed the station for forty years. He received the Hans Egede Medal in 1921. In 1946, he returned to Copenhagen, and was succeeded as station head by Paul Gelting. He was the father of Alf Erling Porsild, Robert Thorbjørn Porsild, Asta Irmelin "Tulle" Egede and Ove Sten Porsild.
Thorvald (Thorwald) Julius Sørensen was a Danish botanist and evolutionary biologist.
Fadenia is an extinct genus of eugeneodontid holocephalian chondrichthyan from the Carboniferous Period of Missouri, the Permian period of Greenland, and the Early Triassic epoch of British Columbia, Canada.
Tupilakosaurus is an extinct genus of dvinosaurian temnospondyl within the family Tupilakosauridae.
Knud Johannes Vogelius Steenstrup was a Danish geologist. He was most noted as an explorer of Greenland.
The Wordie Creek Formation is an uppermost Permian and Lower Triassic geologic formation in Greenland, outcrops of which are located in Northeast Greenland National Park. In 2017, it was suggested to be raised to group status, as the Wordie Creek Group.
Planera is a genus of flowering plants with a single living species, Planera aquatica, the planertree or water elm. The genus has an extensive fossil record dating back to the Cretaceous and spanning the northern hemisphere, with a few southern hemisphere records as well. The living species is found in the southeastern United States, it is a small deciduous tree 10–15 m (390–590 in) tall, closely related to the elms but with a softly, prickly nut 10–15 mm (0.39–0.59 in) diameter, instead of a winged seed. It grows, as the name suggests, on wet sites. Despite its common English name, this species is not a true elm, although it is a close relative of the elms. It is also subject to Dutch elm disease, a disease which affects only members of the Ulmaceae. It is native to most of the southeast United States. It is hardy down to Zone 7.
Nathalie Sophia Nielsine Caroline Rink née Møller was a Danish writer and ethnologist. Together with her husband Hinrich, she founded Greenland's first newspaper, Atuagagdliutit, in 1861. She is credited as being the first woman to publish works on Greenland and its culture.
Selenocara is an extinct genus of mastodonsauroid temnospondyl. The type species is Selenocara groenlandica, described by Gunnar Säve-Söderbergh in 1935 on the basis of skull bones from the Lower Triassic Wordie Creek Formation of Greenland. Säve-Söderbergh originally described it as a new species of Wetlugasaurus.
Sapindopsis ("Sapindus-like") is an extinct form genus for leaves of the Cretaceous Period, originally considered similar to soapberry. Associated reproductive structures now suggest it was more closely related to planes and sycamores of the family Platanaceae.
Sisyrinchium groenlandicum, commonly known as Greenland blue-eyed grass, is a perennial cespitose herb native and endemic to Greenland. It has simple purplish tinged 1–2 mm wide stems and glabrous grass-like leaves and 10–13 mm wide pale blue flowers. It is only known from the areas of Nuup Kangerlua, Ameralik and previously Kangerslussuaq.
