Bornholm is a Danish island in the Baltic Sea, to the east of the rest of Denmark, south of Sweden, northeast of Germany and north of Poland.
Ertholmene is a small archipelago in Denmark. The largest island is Christiansø, whose name is often used with reference to the entire archipelago. Ertholmene are situated 18 kilometres (11 mi) northeast of Gudhjem, Bornholm, and include Denmark's easternmost point. Two of the islands, Christiansø and Frederiksø, are inhabited, with a combined permanent population of 91. The archipelago has a total area of 39 hectares. Its name is derived from the Danish for "pea islands".
Sunnyodon is a genus of tiny, extinct mammal, probably of the Lower Cretaceous. Found in what is now southern England and Denmark, it was a relatively early member of the extinct order of Multituberculata. It is part of the suborder Plagiaulacida and family Paulchoffatiidae.
The Capital Region of Denmark is the easternmost administrative region of Denmark, and contains Copenhagen, the national capital.
Dromaeosauroides is a genus of dromaeosaurid theropod dinosaur from the Early Cretaceous of what is now Denmark and possibly also England. It was discovered in the Jydegaard Formation in the Robbedale valley, on the island of Bornholm in the Baltic Sea. This is the only likely place for dinosaur remains to be discovered on Danish territory, since the Mesozoic deposits exposed in the rest of the country are marine. Dromaeosauroides is the first known dinosaur from Denmark, and the only one which has been scientifically named. It is one of the oldest known dromaeosaurs in the world, and the first known uncontested dromaeosaur from the Early Cretaceous of Europe.
Turiasauria is an unranked clade of basal sauropod dinosaurs known from Middle Jurassic to Early Cretaceous deposits in Europe, North America, and Africa.
The Bornholm Art Museum is situated on the Danish island of Bornholm, above the Sanctuary Rocks (Helligdomsklipperne) about 6 kilometres north-west of Gudhjem, Denmark.
The Alum Shale Formation is a formation of black shale of Miaolingian to Tremadocian in age found predominantly in southern Scandinavia. It is shale or clay slate containing pyrite. Decomposition of pyrite by weathering forms sulfuric acid, which acts on potash and alumina constituents to form alum, which often occurs as efflorescences on the rock outcrop.
Pholidosaurus is an extinct genus of neosuchian crocodylomorph. It is the type genus of the family Pholidosauridae. Fossils have been found in northwestern Germany. The genus is known to have existed during the Berriasian-Albian stages of the Early Cretaceous. Fossil material found from the Annero and Jydegård Formations in Skåne, Sweden and on the island of Bornholm, Denmark, have been referred to as a mesoeucrocodylian, and possibly represent the genus Pholidosaurus.
Helligdomsklipperne are a group of rocks on the island of Bornholm, Denmark, 6 kilometres (3.7 mi) from Gudhjem and 4.9 kilometres (3.0 mi) from Tejn. They are characterised by moderately high coastal cliffs of sharp granite and are about 22 metres (72 ft) high. The name of the rocks originated in the Middle Ages when there was a holy spring close to the coast which attracted pilgrims, especially on Sankt Hans Aften. During the ice age, much of today's coast was below sea level but when the ice melted, the island itself was raised leaving this part of Bornholm's coast some 20 meters above sea level. Coastal cliffs with deep caves and steep craggy granite pillars are typical of this area of the coast as a result of many years exposure to the weather. To the southeast the Kyststi or coastal path leads to the well preserved Døndalen Woods. It is a popular tourist attraction, accessed by boats from Gudhjem harbour. Steps lead from the coast up to the Bornholm Art Museum.
Paradisbakkerne, also Helvedesbakkerne, is a group of hills in Denmark, located in the east of the island of Bornholm. It is situated approximately 3 kilometres (1.9 mi) northwest of Nexø. The privately owned area consists of hilly, rocky landscapes with narrow rift valleys lined by almost vertical cliffs, making it popular for nature walks. Typically, the hills rise to a height of 30–50 metres (98–164 ft) above the surroundings in a forested area which also has a number of small lakes and marshes. Midterpilt, 113 metres (371 ft) above sea level, is one of the highest points. Although much of the area is now wooded, it was once covered with heather and low shrubs, making it suitable for grazing. Paradisbakkerne has a long cultural history, attested by numerous place names with their own legends and stories. These include Slingestenen, Linkisten, Ligstenen, Dybedal, Ravnedal, Majdal, and Gamle Dam.
Rytterknægten is the highest point on the Danish island of Bornholm at 162 metres (531 ft) above sea level. The bierg is situated on a wooded bedrock of gaiter formations in the middle of Almindingen forest. Aakirkeby is located about 5 kilometres (3.1 mi) to the southeast.
Arnager is a small fishing village in Rønne parish, Bornholm island, Denmark. It is approximately 3 kilometres (1.9 mi) southwest of Nylars, about 8 kilometres (5.0 mi) southeast of Rønne, and approximately 3 kilometres (1.9 mi) southeast of Bornholm Airport. Its population in 2010 was 151 residents. Arnager Bay is east of Arnager.
The Jydegaard Formation is a geological formation dating to the Early Cretaceous, about 145–139 million years ago. It is on the island of Bornholm, Denmark. Vertebrate fossils have been found in the formation.
The Rabekke Formation is a geological formation dating to the latest Jurassic or earliest Cretaceous, around 146 to 145 million years ago. The formation crops out on the island of Bornholm, Denmark. Vertebrate fossils have been found in the formation.
The Nyker Group is a group of geological formations from the Early Cretaceous, about 146 to 140 million years ago. It is on the island of Bornholm, Denmark. It includes the Rabekke, Robbedale and Jydegaard Formations.
The Bagå Formation is a geological formation dating to around 176 to 170 million years ago, in the Early and Late Jurassic. It is located on the island of Bornholm, Denmark.
The Hasle Formation is a geologic formation on the island on Bornholm, Denmark. It is of early to late Pliensbachian age. Vertebrate fossils have been uncovered from this formation. The type section of the formation is found at the south of the costal Hasle Town, and it is composed by rusty yellow to brownish siltstones and very fine-grained sandstones. The southernmost arch, Hvjdoddebuen, is not as fossil-bearing as the type unit in Hasle. The formation can be separated in two different petrographic types: type 1 sandstones are friable with layers and lenses of concretionary siderite and type 2 well-cemented sandstones. Both types where deposited in a relatively high-energy marine environment with a diagenetic pattern that demonstrates a close relation to various phases of subsidence and uplift in the tectonically unstable Fennoscandian Border Zone. Most of its deposition happened on a storm-dominated shoreface, with the exposed parts deposited in an open marine shelf within 1–2 km distance from the fault-controlled coastlines. However, recent works have recovered terrestrial fauna from it, including a footprint, suggesting easterly winds and low tide could have exposed the inner parts of the upper shoreface, and create long-lasting Floodplain-type environments. Field works since 1984 have shown a mostly hummocky cross-stratified deposition, with great complexity of the sediments that suggests very complicated and variable flow conditions, with Megaripples derived from storm events. Storms were frequent and the coastline faced a wide epeiric sea with a fetch towards the west of possibly 1000 kilometers. The Jamesoni–Ibex Chronozone in the Central European Basin represents a clear sea Transgression, due to the appearance of ammonites from Thuringia and southern Lower Saxony, showing a full marine ingression towards the west. This rise in the sea level is also measured in the north, as is proven by the presence of Uptonia jamesoni in Kurremölla and Beaniceras centaurus plus Phricodoceras taylori on the Hasle Formation. The whole Hasle Sandstones are a result of this rise in the sea level, where the marine sediments cover the deltaic layers of the Rønne Formation. The rise in the sea level is observed on palynology, as on the Hasle Formation Nannoceratopsis senex (Dinoflajellate) and Mendicodinium reticulaturn appear, indicating a transition from paralic and restricted marine to fully marine.
The Rønne Formation is a geologic formation on the island on Bornholm, Denmark. It is of middle Hettangian to early Pliensbachian age. Vertebrate fossils have been uncovered from this formation. During the Early Jurassic, on what is now the Bornholm region was transitional between continental and marine settings with tidal influence. There was a lower delta plain, with lagoons and intertidal swamps. The formation is correlated with the lower Rya Formation and the upper Höganäs Formation of Skåne, Sweden.
The Sorthat Formation is a geologic formation on the island of Bornholm, Denmark and in the Rønne Graben in the Baltic Sea. It is of Latest Pliensbachian to Late Toarcian age. Plant fossils have been recovered from the formation, along with several traces of invertebrate animals. The Sorthat Formation is overlain by fluvial to lacustrine gravels, along with sands, clay and in some places coal beds that are part of the Aalenian-Bathonian Bagå Formation. Until 2003, the Sorthat Formation was included as the lowermost part of the Bagå Formation, recovering the latest Pliensbachian to lower Aalenian boundary. The Sorthat strata reflect a mostly marginally deltaic to marine unit. Large streams fluctuated to the east, where a large river system was established at the start of the Toarcian. In the northwest, local volcanism that started in the lower Pliensbachian extended along the North Sea, mostly from southern Sweden. At this time, the Central Skåne Volcanic Province and the Egersund Basin expelled most of their material, with influences on the local tectonics. The Egersund Basin has abundant fresh porphyritic nephelinite lavas and dykes of lower Jurassic age, with a composition nearly identical to those found in the clay pits. That indicates the transport of strata from the continental margin by large fluvial channels of the Sorthat and the connected Röddinge Formation that ended in the sea deposits of the Ciechocinek Formation green series.
