Query: When was the Campanian age?
The Campanian is, in the ICS' geologic timescale, the fifth of six ages of the Late Cretaceous epoch (or, in chronostratigraphy: the fifth of six stages in the Upper Cretaceous series). The Campanian spans the time from 83.6 ± 0.7 Ma to 72.1 ± 0.6 Ma (million years ago). It is preceded by the Santonian and it is followed by the Maastrichtian.

There was clear chronological change throughout the Bronze Age. Throughout what archaeologists have termed Period I and Period II (c.1600–1300 BCE) the number of depositions rose rapidly while the content of the depositions also increased with the inclusion of a wide variety of items. The quantity of bronze items declined during Period III (1300–1100 BCE), before rising again in Period IV (1100–900 BCE) and reaching a peak in Period V (900–700 BCE) before a further decline in Period VI (700–500 BCE). Throughout this period there are also other differences that are apparent; bronze objects associated with women are not present in Period I, although have begun to appear by Period II and by Period VI they were the dominant form of artefact in the wetland deposits.
"Republic of Rome" covers the period from 264 B.C. to 43 B.C. Three scenarios cover the Early Republic (roughly the era of the first and second Punic Wars), Mid Republic (the era of the Gracchi), and Late Republic (the time of the Roman civil wars and Julius Caesar). Each player represents a faction in the Roman Senate, with a collection of senators rated for their oratorical and military skills, popularity with the people of Rome, and most importantly, political influence. The goal of the game is to have one of one's senators amass enough Influence to be declared "Consul for Life," or, barring that, have one's faction have most total Influence when the maximum number of game turns have been played.
There has been no absolute dating of the Nemegt Formation. It is, however, almost certainly early Maastrichtian c 71-70 Ma. Gradzinski and others considered a Campanian age possible but more recent research indicates otherwise. A Campanian age no longer seems credible, because the Alagteegian (or lower Djadokhtan, at the locality "Chuluut Uul") has been radiometrically dated at about 73.5 Ma or even younger (a more recent K/Ar date is 71.6 +/- 1.6 Ma). The c 73.5 (or perhaps 72) Ma Alagteegian is separated from the Nemegt by the "classic" Djadokhtan (e.g. Bayan Dzag), later Djadohktan (represented by Ukhaa Tolgod) and Barungoyotian (Khulsan). All these intervening horizons almost certainly represent more than the 1.5 million years between the dated Alagteegian level and the onset of Maastrichtian time (72.1 million Ma according to current dating). Ergo the Nemegt is entirely Maastrichtian. See also Shuvalov, Sochava and Martinsson " The Age of Dinosaurs in Russia and Mongolia." The presence of "Saurolophus" further supports an early Maastrichtian age as the same genus occurs in the early Maastrichtian Horseshoe Canyon formation.

The Cryptic era is an informal term for the earliest geologic evolution of the Earth and Moon. It is the oldest (informal) era of the Hadean eon, and it is commonly accepted to have begun close to 4533 million (about 4.533 billion) years ago when the Earth and Moon formed. No samples exist to date the transition between the Cryptic era and the following Basin Groups era for the Moon (see also Pre-Nectarian), though sometimes it is stated that this era ended 4150 million years ago for one or both of these bodies. Neither this time period, nor any other Hadean subdivision, has been officially recognized by the International Commission on Stratigraphy.
All specimens of "Catopsbaatar" are known from the Red Beds of Hermiin Tsav formation, except for one molar from the Barun Goyot Formation. The formations are considered coeval (of the same geological age), contain many of the same animals, and probably date to the late Campanian age of the Late Cretaceous Period (about 72 million years ago). The rock facies of the Red Beds of Hermiin Tsav formation consist of orange-coloured, thick-bedded sandstone, with a thin interbedding of light-coloured silt stones and claystones. The rock facies of the Barun Goyot Formation are considered to be the result of an arid or semi-arid environment, with aeolian (deposited by wind) beds.
The Aceramic Neolithic period began roughly around 8500 BC and can be identified with over a half a dozen sites. The period was most prominent in Western Asia in an economy based on the cultivation of crops or the rearing of animals or both. Aceramic Neolithic groups are more rare outside Western Asia. Aceramic Neolithic villages had many attributes of agricultural communities: large settlement size, substantial architecture, long settlement duration, intensive harvesting of seeds with sickles, equipment and facilities for storing and grinding seeds, and containers. Morphological evidence for domestication of plants comes only from Middle PPNB (Pre-Pottery Neolithic B), and by Late PPNB some animals, notably goats, were domesticated or at least managed in most of the sites.
The Sidicini were mentioned for the first time in 343 BC, when the Samnites declared war on them. The Samnites sought to take Teano because of its position as a regional crossroad . The sidicini then sought the help of the Campanians. The Campanians sent an army to assist the Sidicini but were beaten in battle by the Samnites, the Samnites then seized the Tifata hills overlooking Capua (the main Campani city) and, having left a strong force to hold them, marched into the plain between the hills and Capua. There they defeated the Campanians in a second battle and drove them within their walls. At this point the Campanians decided to surrender themselves unconditionally into the power of Rome, following which the Romans felt compelled to intervene to protect their new subjects against further Samnite attacks.
The Middle Paleolithic (or Middle Palaeolithic) is the second subdivision of the Paleolithic or Old Stone Age as it is understood in Europe, Africa and Asia. The term Middle Stone Age is used as an equivalent or a synonym for the Middle Paleolithic in African archeology. The Middle Paleolithic broadly spanned from 300,000 to 30,000 years ago. There are considerable dating differences between regions. The Middle Paleolithic was succeeded by the Upper Paleolithic subdivision which first began between 50,000 and 40,000 years ago. Pettit and White date the Early Middle Paleolithic in Great Britain to about 325,000 to 180,000 years ago (late Marine Isotope Stage 9 to late Marine Isotope Stage 7), and the Late Middle Paleolithic as about 60,000 to 35,000 years ago.
The Amazonian is a geologic system and time period on the planet Mars characterized by low rates of meteorite and asteroid impacts and by cold, hyperarid conditions broadly similar to those on Mars today. The transition from the preceding Hesperian period is somewhat poorly defined. The Amazonian is thought to have begun around 3 billion years ago, although error bars on this date are extremely large (~500 million years). The period is sometimes subdivided into the Early, Middle, and Late Amazonian. The Amazonian continues to the present day.
The Celtiberian inscriptions have been found mainly in the Ebro valley and near the sources of the Tagus and Douro rivers, where Roman and Greek sources place the Celtiberian people. The Celtiberian inscriptions were made on different types of objects (silver and bronze coins, ceramic receptacles, bronze plaques and tesseras, amphores, stones, spindle-whorls, etc.). There are just under two hundred surviving inscriptions, one of which is exceptionally long: the third Botorrita bronze plaque (Zaragoza) with more than three thousand signs containing a census of nearly 250 people. Almost always the direction of the writing is left to right. The fact that nearly all the Celtiberian inscriptions were found out of archaeological context does not allow a precise chronology to be established, but it seems that the earliest inscriptions in the Celtiberian script date from the 2nd century BCE while the latest ones date from the 1st century BCE.
During the Paleolithic era (20,000-10,000 BC) humans lived in several caves above the valley floor during the summer. The caves, Schnurenloch, Mamilchloch, Zwergliloch and Chniechälebalm, contained about 5,000 bones from the now extinct cave bear which the inhabitants had butchered. While no human remains were discovered, a number of stone tools were found. Today the tools and bones are at the Historical Museum of Bern while the caves can be visited with tour groups. These caves and other nearby rock shelters continued to be used through the Neolithic, the late Bronze Age and into the Middle Ages. After the collapse of the Western Roman Empire, Alamanni tribes settled in the Simmen valley and established villages and alpine pastures.
Hence, a crucial question is whether the Anatolian branch split off before the beginning of the Bronze Age, or even the Chalcolithic. A Bronze Age society is usually reconstructed from PIE vocabulary, but it is unclear whether this necessarily holds for inherited vocabulary in Anatolian. The Early Bronze Age starts in Anatolia at least with the beginning of the 3rd Millennium cal. BC. In the Caucasus the Bronze Age begins roughly 3300 BC. It is possible that the Proto-Anatolians were involved with the earliest development of Bronze metallurgy. In any case, while evidence that Anatolian shares common terminology of metallurgy with other branches would speak against Indo-Hittite, discarding the value of this evidence does not automatically favour the concept of Indo-Hittite, since even a 'moderate Indo-Hittite' split around 4000 BC would clearly predate the Bronze Age.
The Phanerozoic eon began following the Precambrian. The first major unit of time it contained was the Cambrian period of the Paleozoic era. At the time, earth's continents were in a very different arrangement and were generally smaller than they are today. The southeastern part of the US was connected to South America and Africa and located in the polar latitudes of the southern hemisphere. The western states were located near the equator.
Between the 8th and 13th centuries, however, the Carolingian chant commissioned by Charlemagne developed into what we now know as Gregorian chant, which began to influence and eventually replace most of the other Western plainchant traditions. By the 12th century, the Mozarabic, Gallican, Celtic, Old Roman, and Beneventan chant traditions had all been effectively superseded by Gregorian chant. Ambrosian chant alone survived, despite the efforts of several Popes over a period of several centuries to establish Gregorian hegemony. A chronicle by the Milanese historian Landolphus from around the year 1000 recounts a legend that two Sacramentaries, one Gregorian and one Ambrosian, were placed on an altar to see which chant had divine acceptance; miraculously, both books opened simultaneously, showing both were equally acceptable.
The Phanerozoic is the current eon on Earth, which started approximately 542 million years ago. It consists of three eras: The Paleozoic, Mesozoic, and Cenozoic, and is the time when multi-cellular life greatly diversified into almost all the organisms known today.
Metal tools first appeared in Wales about 2500 BC, initially copper followed by bronze. The climate during the Early Bronze Age (c. 2500–1400 BC) is thought to have been warmer than at present, as there are many remains from this period in what are now bleak uplands. The Late Bronze Age (c. 1400–750 BC) saw the development of more advanced bronze implements. Much of the copper for the production of bronze probably came from the copper mine on the Great Orme, where prehistoric mining on a very large scale dates largely from the middle Bronze Age. Radiocarbon dating has shown the earliest hillforts in what would become Wales, to have been constructed during this period. Historian John Davies, theorises that a worsening climate after around 1250 BC (lower temperatures and heavier rainfall) required more productive land to be defended.
The Ediacaran Period (), spans 94 million years from the end of the Cryogenian Period 635 million years ago (Mya), to the beginning of the Cambrian Period 541 Mya. It marks the end of the Proterozoic Eon, and the beginning of the Phanerozoic Eon. It is named after the Ediacara Hills of South Australia.
The Middle Stone Age (or MSA) was a period of African prehistory between the Early Stone Age and the Later Stone Age. It is generally considered to have begun around 280,000 years ago and ended around 50–25,000 years ago. The beginnings of particular MSA stone tools have their origins as far back as 550–500,000 years ago and as such some researchers consider this to be the beginnings of the MSA. The MSA is often mistakenly understood to be synonymous with the Middle Paleolithic of Europe, especially due to their roughly contemporaneous time span, however, the Middle Paleolithic of Europe represents an entirely different hominin population, "Homo neanderthalensis", than the MSA of Africa, which did not have Neanderthal populations. Additionally, current archaeological research in Africa has yielded much evidence to suggest that modern human behavior and cognition was beginning to develop much earlier in Africa during the MSA than it was in Europe during the Middle Paleolithic. The MSA is associated with both anatomically modern humans ("Homo sapiens") as well as archaic "Homo sapiens", sometimes referred to as "Homo helmei". Early physical evidence comes from the Gademotta Formation in Ethiopia, the Kapthurin Formation in Kenya and Kathu Pan in South Africa.
The Campanian Ignimbrite eruption (CI, also CI Super-eruption) was a major volcanic eruption in the Mediterranean during the late Quaternary, classified at 7 on the Volcanic Explosivity Index (VEI). The event has been attributed to the Archiflegreo volcano, the caldera of the Phlegraean Fields, located west of Mount Vesuvius under the western outskirts of the city of Naples and the Gulf of Pozzuoli, Italy. Estimates of the date, magnitude and the amount of ejected material have varied considerably during several centuries of investigation. This applies to most significant volcanic events that originated in the Campanian Plain, as it is one of the most complex volcanic structures in the world. However, continued research, advancing methods and accumulation of volcanological, geochronological, and geochemical data has amounted to ever more precise dating.
Campanian vase painting is one of the five regional styles of South Italian red-figure vase painting. It forms a close stylistic community with Apulian vase painting.
Campania produced red-figure vases in the 5th and 4th centuries BC. The sand-coloured to light brown clay (lighter than other South Italian clays) of Campania was covered with a slip that developed a pink or red tint after firing, creating an appearance very similar to that of Attic vases. The popular white or bright paints were visually especially striking on this. Women are usually by the use of white paint to depict their skin. The Campanian painters preferred smaller vessel types, but also "hydriai" and bell "kraters". The most popular shape is the bail-amphora. Many typical Apulian vessel shapes, like volute kraters, column kraters, "loutrophoroi", "rhyta" and "nestoris" amphorae are absent, "pelikes" are rare. The repertoire of motifs is limited. Subjects include youths, women, thiasos scenes, birds and animals, and often native Samnite warriors. The backs often show cloaked youths. Mythological scenes and depictions related to burial rites play a subsidiary role. "Naiskos" scenes, ornamental elements and polychromy are adopted after 340 BC under Lucanian influence. The bell-shaped flowers used as ornaments are very different from the ornaments used in other South Italian styles. At 4,000 known vases, the Campanian style is the second most common in the region (after Apulian).
The workshop in Cumae was founded very late. After 350 BC, its founder, the CA Painter and his collaborators and successors worked there. The CA Painter is considered as the outstanding artist of his group, or even of Campanian vase painting as a whole. From 330 onwards, a strong Apulian influence is visible. The most common motifs are "naiskos" and grave scenes, dionysiac scenes and symposia. Depictions of bejewelled female heads are also common. The CA painter was polychrome but tended to use much white for architecture and female figures. His successors, the CB Painter and CC Painter were not fully able to maintain his quality, leading to a rapid demise, terminating with the end of Campanian vase painting around 300 BC.
During the Campanian age, a radiation among dinosaur species occurred. In North America, for example, the number of known dinosaur genera rises from 4 at the base of the Campanian to 48 in the upper part. This development is sometimes referred to as the "Campanian Explosion". However, it is not yet clear if the event is artificial, i.e. the low number of genera in the lower Campanian can be caused by a lower preservation chance for fossils in deposits of that age. The generally warm climates and large continental area covered in shallow sea during the Campanian probably favoured the dinosaurs. In the following Maastrichtian stage, the number of North American dinosaur genera found is 30% less than in the upper Campanian.
