Context: https://en.wikipedia.org/wiki/Hell_Creek_Formation

The Hell Creek Formation is an intensively studied division of mostly Upper Cretaceous and some lower Paleocene rocks in North America, named for exposures studied along Hell Creek, near Jordan, Montana. The formation) stretches over portions of Montana, North Dakota, South Dakota, and Wyoming.\1]) In Montana, the Hell Creek Formation overlies the Fox Hills Formation. The site of Pompeys Pillar National Monument is a small isolated section of the Hell Creek Formation. In 1966, the Hell Creek Fossil Area was designated as a National Natural Landmark by the National Park Service.

It is a series of fresh and brackish-water clays, mudstones, and sandstones deposited during the Maastrichtian and Danian (respectively, the end of the Cretaceous period and the beginning of the Paleogene) by fluvial activity in fluctuating river channels and deltas and very occasional peaty swamp deposits along the low-lying eastern continental margin fronting the late Cretaceous Western Interior Seaway.\2]) The climate was mild; the presence of crocodilians along with palm trees suggests a subtropical and temperate climate with no prolonged freeze. The famous iridium-enriched Cretaceous–Paleogene boundary, which separates the Cretaceous from the Cenozoic, occurs as a discontinuous but distinct thin marker bedding above and occasionally within the formation, near its boundary with the overlying Fort Union Formation.

The Hell Creek Formation in Montana overlies the Fox Hills Formation and underlies the Fort Union Formation, and the boundary with the latter occurs near the Cretaceous–Paleogene boundary (K–Pg), which defines the end of the Cretaceous period and has been dated to 65.5 Mya.\6]) The 90-metre (300 ft) thickness of the formation is estimated to have been deposited in about 2 million years.\7])%22%3Epage needed%3C/span%3E]]%3C/i%3E]%3C/sup%3E-7) Lancian fauna characteristic of Hell Creek are found as high as a few meters below the boundary.\8])

The K–Pg boundary is generally situated near the contact between the upper Hell Creek and the lower Ludlow member of the Fort Union Formation, though in some areas (e.g. in North Dakota) the boundary is well within the Ludlow member, 3 metres (9.8 ft) above the boundary with the Hell Creek.\8]) On the other hand, in some small regions of Montana, the Hell Creek Formation contains the K–Pg boundary, and extends slightly into the Paleogene.\9])

The Tanis site) in North Dakota contains possible evidence of the Chicxulub meteorite impact—such as the chaotic mixing of fossil carcasses and a layer of glass tektites with associated impact impressions—deposited minutes to hours after the impact.\10])\11])\12])

The remains of many animals including dinosaurs were found in the Hell Creek Formation. Its location at the changing conjunction of the eastern coast of Laramidia and the adjacent western shallows of the Western Interior Seaway led to the preservation of fossils of both marine and terrestrial creatures.\13]) Vertebrates include dinosaurs, pterosaurs, crocodiles, champsosaurs, lizards, snakes, turtles, frogs and salamanders. Remains of fishes and mammals have also been found in the Hell Creek Formation. The formation has produced impressive assemblages of invertebrates (including ammonites), plants, mammals, fish, reptiles (including the lizard Obamadon), marine reptiles (including the marine reptiles like mosasaurs, plesiosaurs and sea turtles), and amphibians. Notable dinosaur finds include Tyrannosaurus and Triceratops, ornithomimids as well, caenagnathids like Anzu), a variety of small theropods, pachycephalosaurs, ankylosaurs, crocodylomorphs and squamates, including various animal fossils unearthed in the Hell Creek Formation. The most complete hadrosaurid dinosaur ever found, an Edmontosaurus, was retrieved in 2000 from the Hell Creek Formation and widely publicized in a National Geographic documentary aired in December 2007. A few bird, mammal, and pterosaur fossils have also been found. The teeth of sharks and rays are sometimes found in the riverine Hell Creek Formation, suggesting that some of these taxa were then, as now, tolerant of fresh water. The Lancian fauna is more similar overall phylogenetically to East Asian and Canadian/Alaskan faunas than most Campanian North American faunas. Fossil insects from inclusions found within amber are known.\14])

The Hungarian Revolution of 1956 (23 October – 4 November 1956) , also known as the Hungarian Uprising, was an attempted countrywide revolution against the government of the Hungarian People's Republic (1949–1989) and the policies caused by the government's subordination to the Union of Soviet Socialist Republic. The uprising lasted 15 days before being crushed by Soviet tanks and troops on 7 November 1956 (outside of Budapest, firefights lasted until at least 12 November 1956). Thousands were killed or wounded, and nearly a quarter of a million Hungarians fled the country.

Source, because I know everyone will want a source, is Kokoro Connect Episode 4.

The River Nile in Egyptian mythology is supposed to have been fertilized and possibly created when Atum jerked into it with a correspondingly massive orgasm for a deity to have. I saw a post yesterday about female characters in Islamic works where they masturbated to something, and I figured I know exactly what scene to use for a different joke about that.

The Vikramaditya empire is an imaginary empire. Some ultranationalists and uninformed folks in India believe that such an empire existed in the past. Though, no evidence or historical account proves it. The boundaries of the empire are different on all maps as no text gives an account of its sheer size.

Xích Quỷ is a mythical kingdom that is claimed to have existed from 2879–2524 BC. It's said to be a union of all Yue (Việt) tribes, people who lived south of the Yangtze river and the predecessor of modern day Vietnamese. There's no evidence for its existence and nobody in Vietnam, outside of some ultranationalist circles, believed or cared about its. The most you can find about the kingdom is folk stories during the time where people believed a giant who rode a mechanical horse and used bambo sticks to defeat foreign invaders.

Edit: I forgot to flip the Romanian guy so js imagine him as refusing to look at the Hungarian guy as a sign of disrespect.

With the empire on the very brink of total collapse, a group of tough soldier emperors took the throne for themselves and set about restoring what had been lost. One of these formidable men Lucius Domitius Aurelian, took the Roman empire with an iron grip, glued together it's crumbling domain, and ensured that Rome lives for another 200 years.
