The Dracoisen Formation is a geologic formation [1] found on the islands of Spitsbergen and Nordaustlandet in Svalbard, Norway. It is Ediacaran (uppermost Neoproterozoic) in age. Microfossils have been found, including Bavinella faveolata and rare acritarchs. [2] [3]
Svalbard is an archipelago in the Arctic Ocean roughly centered on 78° north latitude and 20° east longitude. The archipelago is the northernmost part of the Kingdom of Norway. The three main islands in the group consist of Spitsbergen, Nordaustlandet and Edgeøya. There are also a number of smaller islands, such as Barents Island (Barentsøya), Kvitøya, Prins Karls Forland, Kongsøya, Bear Island, Svenskøya, Wilhelm Island and other smaller islands or skerries.
Nordaustlandet is the second-largest island in the archipelago of Svalbard, Norway, with an area of 14,443 square kilometres (5,576 sq mi). It lies north east of Spitsbergen, separated by Hinlopen Strait. Much of Nordaustlandet lies under large ice caps, mainly Austfonna and Vestfonna, the remaining parts of the north being tundra inhabited by reindeer and walruses. The island is uninhabited and lies entirely within Nordaust-Svalbard Nature Reserve.
The Hinlopen Strait is the strait between Spitsbergen and Nordaustlandet in Svalbard, Norway. It is 150 kilometers (93 mi) long and 10 to 60 kilometers wide. The strait is difficult to pass because of pack ice. It is believed to have been named after Thijmen Jacobsz Hinlopen.
The geology of Norway encompasses the history of Earth that can be interpreted by rock types found in Norway, and the associated sedimentological history of soils and rock types.
Nordaust-Svalbard Nature Reserve is located in the north-eastern part of the Svalbard archipelago in Norway. The nature reserve covers all of Nordaustlandet, Kong Karls Land, Kvitøya, Sjuøyane, Storøya, Lågøya, Wilhelm Island, Wahlbergøya and a small section of the north-east corner of Spitsbergen. The reserve is 55,354 square kilometres (21,372 sq mi), of which 18,663 square kilometres (7,206 sq mi) is on land and 36,691 square kilometres (14,166 sq mi) is on water—making it the largest preserved area in Norway. It includes the largest glacier in Norway, Austfonna, as well as Vestfonna and parts of Olav V Land. The reserve has been protected since 1 July 1973 and borders in the south to Søraust-Svalbard Nature Reserve.
Palvennia is an extinct genus of ophthalmosaurid ichthyosaurian known from the uppermost Jurassic of Central Spitsbergen, Norway. It was named for PalVenn, the Friends of the Palaeontological Museum in Oslo, whose expedition led to the discovery of the type specimen. Palvennia is known from a single skull from the Slottsmøya Member of the Agardhfjellet Formation. The skull is 860 mm long, but is unusual in having a very short rostrum, similar to Ichthyosaurus breviceps. Because of this, the orbit seems very large, but this may be effected by crushing. The single and only known species is Palvennia hoybergeti Druckenmiller et al., 2012. In 2019, Palvennia was synonymized with Arthropterygius, though maintained as a separate species, by Nikolay Zverkov and Natalya Prilepskaya, although this synonymy was objected to later that same year by Lene Delsett and colleagues, who maintained that they were sufficiently different to warrant separate genera.

The Brigus Formation is a fossiliferous upper lower Cambrian geologic formation in Newfoundland and Labrador.
The Conception Group is a geologic group in Newfoundland and Labrador. It preserves fossils dating back to the Ediacaran period. It mainly contains turbidites, but is interrupted by a glacial diamictite, and tops out with sand and siltstones . It corresponds to the lower portion of the Connecting Point Group

The geology of Svalbard encompasses the geological description of rock types found in Svalbard, and the associated tectonics and sedimentological history of soils and rocks. The geological exploration of Svalbard is an ongoing activity, and recent understandings may differ from earlier interpretations.
