The '''aurochs''' ('''''Bos primigenius'''''; {{IPAc-en|ˈ|ɔː|r|ɒ|k|s}} or {{IPAc-en|ˈ|aʊ|r|ɒ|k|s}}; pl.: '''aurochs''' or '''aurochsen''') is an [[extinct]] species of [[Bovini|bovine]], considered to be the wild ancestor of modern domestic [[cattle]]. With a shoulder height of up to {{cvt|1.8|m}} in bulls and {{cvt|1.55|m}} in cows, it was one of the largest [[herbivore]]s in the [[Holocene]]; it had massive elongated and broad horns that reached {{cvt|80|cm}} in length.

The aurochs was part of the [[Pleistocene megafauna]]. It probably evolved in Asia and migrated west and north during warm [[interglacial]] periods. The oldest-known aurochs fossils date to the [[Middle Pleistocene]]. The species had an expansive range spanning from Western Europe and North Africa to the Indian subcontinent and East Asia. The distribution of the aurochs progressively contracted during the Holocene due to [[habitat loss]] and hunting, with the last known individual dying in the [[Jaktorów]] forest in Poland in 1627.

There is a long history of interaction between aurochs and humans, including archaic hominins like [[Neanderthals]]. The aurochs is depicted in [[Paleolithic]] [[cave painting]]s, [[Neolithic]] [[petroglyph]]s, [[Ancient Egypt]]ian [[relief]]s and [[Bronze Age]] figurines. It symbolised power, sexual potency and prowess in [[religions of the ancient Near East]]. Its horns were used in [[votive offering]]s, as [[trophies]] and [[drinking horn]]s.

Two aurochs [[domestication]] events occurred during the [[Neolithic Revolution]]. One gave rise to the domestic [[cattle|taurine cattle]] (''Bos taurus'') in the [[Fertile Crescent]] in the [[Near East]] that was introduced to Europe via the [[Balkans]] and the coast of the [[Mediterranean Sea]]. [[Hybrid (biology)|Hybrid]]isation between aurochs and early domestic cattle occurred during the early Holocene. Domestication of the [[Indian aurochs]] led to the [[zebu]] cattle (''Bos indicus'') that hybridised with early taurine cattle in the [[Near East]] about 4,000 years ago. Some modern cattle breeds exhibit features reminiscent of the aurochs, such as the dark colour and light eel stripe along the back of bulls, the lighter colour of cows, or an aurochs-like horn shape.

== Etymology ==
Both "aur" and "ur" are [[Germanic languages|Germanic]] or [[Celtic languages|Celtic]] words meaning "wild ox".<ref>{{Cite book |last=Partridge |first=E. |author-link=Eric Partridge |title=Origins: A Short Etymological Dictionary of Modern English |publisher=Greenwich House |year=1983 |location=New York |isbn=978-0-517-41425-5 |page=523 |chapter=Urus, Uri gallica |chapter-url=https://archive.org/details/anetymologicald00valpgoog/page/523/mode/2up}}</ref><ref name=lewis>{{cite book |last1=Lewis |first1=C.

In [[Old High German]], this word was [[Compound (linguistics)|compounded]] with ''ohso'' ('ox') to ''ūrohso'', which became the early modern ''Aurochs''.<ref name=vVuure05/> The [[Latin]] word "urus" was used for wild ox from the [[Gallic Wars]] onwards.<ref name=lewis/><ref name=gallicwars>{{cite book |last=McDevitte |first=W.

The use of the plural form ''{{lang|en|aurochsen}}'' in English is a direct parallel of the German plural ''Ochsen'' and recreates the same distinction by analogy as English singular ''ox'' and plural ''oxen'', although ''aurochs'' may stand for both the singular and the plural term; both are attested.<ref>{{cite book |last=Crystal|first=David |author-link=David Crystal |title=The Cambridge Encyclopedia of the English Language |publisher=[[Cambridge University Press]] |place=Cambridge |year=2003 |edition=Third |isbn= 978-1-108-43773-8 |page=213}}</ref><ref>{{cite book |chapter-url=https://www.researchgate.net/publication/321290645 |title=Resurrecting Extinct Species |author1=Campbell, D.I. |author2=Whittle, P.M. |chapter=Three Case Studies: Aurochs, Mammoths and Passenger Pigeons |name-list-style=amp |publisher=[[Palgrave Macmillan]] |place=Cham |page=30 |year=2017 |isbn=978-3-319-69578-5 |doi=10.1007/978-3-319-69578-5_2}}</ref>

=== Subspecies ===
Three aurochs [[subspecies]] have traditionally been recognised to have existed in historical times:
* The Eurasian aurochs (''B. p. primigenius'') was part of the [[Pleistocene megafauna]] in [[Eurasia]] and survived until the [[17th century]] in [[Eastern Europe]].<ref name=Bollongino_al2012>{{cite journal |author1=Bollongino, R. |name-list-style=amp |author2=Burger, J. |author3=Powell, A. |author4=Mashkour, M. |author5=Vigne, J.-D. |author6=Thomas, M.

Chinese geneticists published [[mitochondrial DNA]] evidence supporting that Eurasian aurochs populations from [[northern China]] were genetically isolated for large stretches of the [[Pleistocene]], and as a result distinctive enough to be considered a separate subspecies, the East Asian aurochs (''B. p. sinensis''), even if this was not morphologically distinct.<ref name=Hou/>

At least two [[insular dwarfism|dwarf subspecies]] of aurochs developed on [[Mediterranean Sea|Mediterranean]] islands as a result of sea level changes during the Pleistocene:

According to a 16th-century description by [[Sigismund von Herberstein]], the aurochs was pitch-black with a grey streak along the back; his wood carving made in 1556 was based on a culled aurochs, which he had received in [[Mazovia]].<ref>{{cite journal |last=Senglaub, K. |year=2002 |title=Sigmund von Herberstein (1486–1566) und die historischen Konfusionen um Ur und Wisent |journal=Säugetierkundliche Informationen |volume=5 |issue=26 |pages=253–266 |doi= |url=https://www.zobodat.at/biografien/Herberstein_Sigmund_von_Saeugetierkdl-Inf_26_0253-0266.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://www.zobodat.at/biografien/Herberstein_Sigmund_von_Saeugetierkdl-Inf_26_0253-0266.pdf |archive-date=2022-10-09 |url-status=live}}</ref> In 1827, [[Charles Hamilton Smith]] published an image of an aurochs that was based on an [[oil painting]] that he had purchased from a merchant in [[Augsburg]], which is thought to have been made in the early 16th century.<ref>{{cite book |last=Lydekker, R. |author-link=Richard Lydekker |year=1912 |location=London |publisher=Methuen &Co.

Both sexes had a light-coloured muzzle, but evidence for variation in coat colour does not exist. Egyptian grave paintings show cattle with a reddish-brown coat colour in both sexes, with a light saddle, but the horn shape of these suggest that they may depict domesticated cattle.<ref name="vVuure05"/>
Many primitive cattle breeds, particularly those from Southern Europe, display similar coat colours to the aurochs, including the black colour in bulls with a light eel stripe, a pale mouth, and similar sexual dimorphism in colour.<ref name="vVuure05"/><ref name="Frisch"/> A feature often attributed to the aurochs is blond forehead hairs. According to historical descriptions of the aurochs, it had long and curly forehead hair, but none mentions a certain colour. Although the colour is present in a variety of primitive cattle breeds, it is probably a discolouration that appeared after domestication.<ref name="vVuure05"/>

=== Body shape ===

The proportions and body shape of the aurochs were strikingly different from many modern cattle breeds. For example, the legs were considerably longer and more slender, resulting in a shoulder height that nearly equalled the trunk length. The skull, carrying the large horns, was substantially larger and more elongated than in most cattle breeds. As in other wild bovines, the body shape of the aurochs was athletic, and especially in bulls, showed a strongly expressed neck and shoulder musculature. Therefore, the fore hand was larger than the rear, similar to the wisent, but unlike many domesticated cattle. Even in carrying cows, the udder was small and hardly visible from the side; this feature is equal to that of other wild bovines.<ref name="vVuure05"/>

=== Size ===
The aurochs was one of the largest [[herbivore]]s in [[Holocene]] Europe. The size of an aurochs appears to have varied by region, with larger specimens in northern Europe than farther south. Aurochs in Denmark and Germany ranged in height at the shoulders between {{cvt|1.8|m}} in bulls and {{cvt|1.35-1.55|m}} in cows, while aurochs bulls in [[Hungary]] reached {{cvt|1.6|m}}.<ref name="Kysely2008">{{cite journal |last=Kysely |first=R. |year=2008 |title=Aurochs and potential crossbreeding with domestic cattle in Central Europe in the Eneolithic period.

The African aurochs was similar in size to the European aurochs in the Pleistocene, but declined in size during the transition to the Holocene; it may have also varied in size geographically.<ref name=Linseele2004>{{cite journal |last=Linseele, V. |year=2004 |title=Size and size change of the African aurochs during the Pleistocene and Holocene |journal=Journal of African Archaeology |volume=2 |issue=2 |pages=165–185 |doi=10.3213/1612-1651-10026 |url=https://www.researchgate.net/publication/269674903}}</ref>

The body mass of aurochs appears to have shown some variability. Some individuals reached around {{cvt|700|kg|-1}}, whereas those from the late Middle Pleistocene are estimated to have weighed up to {{cvt|1500|kg|-1}}.<ref name="vVuure05"/> The aurochs exhibited considerable [[sexual dimorphism]] in the size of males and females.<ref name=vuure>{{cite journal |last=Van Vuure |first=T. |date=2002 |title=History, morphology and ecology of the Aurochs (''Bos primigenius'') |journal=Lutra |volume=45 |issue=1 |pages=1–16 |citeseerx=10.1.1.534.6285 }}</ref>

=== Horns ===
The horns were massive, reaching {{cvt|80|cm}} in length and between {{cvt|10|and|20|cm}} in diameter.<ref name="Frisch"/> Its horns grew from the skull at a 60-degree angle to the muzzle facing forwards and were curved in three directions, namely upwards and outwards at the base, then swinging forwards and inwards, then inwards and upwards. The curvature of bull horns was more strongly expressed than horns of cows.<ref name="vVuure05"/> The basal circumference of [[horn core]]s reached {{cvt|44.5|cm}} in the largest Chinese specimen and {{cvt|48|cm}} in a French specimen.<ref name=zongg/> Some cattle breeds still show horn shapes similar to that of the aurochs, such as the Spanish fighting bull, and occasionally also individuals of derived breeds.<ref name="vVuure05"/>

A well-preserved aurochs bone yielded sufficient mitochondrial DNA for a [[sequence analysis]] in 2010, which showed that its genome consists of 16,338 [[base pairs]].<ref>{{cite journal |author1=Edwards, C.J. |author2=Magee, D.A. |author3=Park, S.D.E. |author4=McGettigan, P.A. |author5=Lohan, A.J. |name-list-style=amp |year=2010 |title=A complete mitochondrial genome sequence from a mesolithic wild Aurochs (''Bos primigenius'') |journal=PLOS ONE |volume=5 |issue=2 |article-number=e9255 |doi=10.1371/journal.pone.0009255 |doi-access=free |pmid=20174668 |pmc=2822870 |bibcode=2010PLoSO...5.9255E}}</ref> Further studies using the aurochs whole genome sequence have identified candidate microRNA-regulated [[Genomics of domestication|domestication genes]].<ref>{{Cite journal |last1=Braud |first1=M. |last2=Magee|first2=D.A. |last3=Park |first3=S.D.E. |last4=Sonstegard |first4=T.S. |last5=Waters|first5=S.M. |last6=MacHugh |first6=D.E. |last7=Spillane|first7=C. |date=2017 |title=Genome-wide microRNA binding site variation between extinct wild Aurochs and modern cattle identifies candidate microRNA-regulated domestication genes |journal=Frontiers in Genetics |volume=8 |page=3 |doi=10.3389/fgene.2017.00003 |pmc=5281612 |pmid=28197171 |doi-access=free |name-list-style=amp}}</ref> A comprehensive sequence analysis of Late Pleistocene and Holocene aurochs published in 2024 suggested that Indian aurochs (represented by modern zebu cattle) were the most genetically divergent aurochs population, having diverged from other aurochs around 300–166,000 years ago, with other aurochs populations spanning Europe and the Middle East to East Asia sharing much more recent common ancestry within the last 100,000 years. Late Pleistocene European aurochs were found to have a small (~3%) ancestry component from a divergent lineage that split prior to the divergence of Indian and other aurochs, suggested to be residual from earlier European aurochs populations. Towards the end of the Late Pleistocene, European aurochs experienced considerable gene flow from Middle Eastern aurochs.

[[Mating]] season was in September, and calves were born in spring.<ref name=Geptner1961/> Rutting bulls had violent fights, and evidence from the [[Jaktorów]] forest shows that they were fully capable of mortally wounding one another. In autumn, aurochs fed for the winter, gaining weight and possessing a shinier coat than during the rest of the year. Calves stayed with their mothers until they were strong enough to join and keep up with the herd on the feeding grounds. Aurochs calves would have been vulnerable to predation by [[grey wolves]] (''Canis lupus'') and [[brown bears]] (''Ursus arctos''), while the immense size and strength of healthy adult aurochs meant they likely did not need to fear most predators.<ref name=vVuure05/> According to historical descriptions, the aurochs was swift despite its build, could be very aggressive if provoked, and was not generally fearful of humans.<ref name="vVuure05" /> In Middle Pleistocene Europe, aurochs were likely predated upon by the "European jaguar" ''[[Panthera gombaszogensis]]'' and the [[Homotherium|scimitar toothed-cat]] (''Homotherium latidens''),<ref>{{Cite journal |last1=Domingo |first1=L. |last2=Rodríguez-Gómez |first2=G. |last3=Libano |first3=I. |last4=Gómez-Olivencia |first4=A. |date=2017 |title=New insights into the Middle Pleistocene paleoecology and paleoenvironment of the Northern Iberian Peninsula (Punta Lucero Quarry site, Biscay): A combined approach using mammalian stable isotope analysis and trophic resource availability modeling |journal=Quaternary Science Reviews |volume=169 |pages=243–262 |doi=10.1016/j.quascirev.2017.06.008 |bibcode=2017QSRv..169..243D}}</ref> with evidence for the consumption of aurochs by [[cave hyena]]s (''Crocuta'' (''Crocuta'') ''spelaea'') having been found from Late Pleistocene Italy.<ref>{{Cite journal |last1=Crezzini |first1=J. |last2=Boscato |first2=P. |last3=Ricci |first3=S. |last4=Ronchitelli |first4=A. |last5=Spagnolo |first5=V. |last6=Boschin |first6=F. |date=2016 |title=A spotted hyaena den in the Middle Palaeolithic of Grotta Paglicci (Gargano promontory, Apulia, Southern Italy) |journal=Archaeological and Anthropological Sciences |volume=8 |issue=2 |pages=227–240 |doi=10.1007/s12520-015-0273-0 |bibcode=2016ArAnS...8..227C}}</ref> The [[lion]] (''Panthera leo''), [[tiger]] (''Panthera tigris'') and wolf are thought to have been the aurochs' main predators during the Holocene.<ref name=vuure/>

By the 13th century, the aurochs existed only in small numbers in [[Eastern Europe]], and hunting it became a privilege of nobles and later royals.<ref name="vVuure05" /> The population in [[Hungary]] was declining from at least the 9th century and was extinct in the 13th century.<ref>{{cite journal |last=Bartosiewicz, L. |year=2006 |title=Interdisciplinary analysis of an Iron Age Aurochs horn core from Hungary: a case study |journal=Acta Archaeologica Academiae Scientiarum Hungaricae |volume=57 |issue=1–3 |pages=153–163 |doi=10.1556/AArch.57.2006.1-3.10}}</ref><ref>{{cite journal |last=Bartosiewicz, L. |year=1997 |title=A horn worth blowing?

Findings from [[subfossil]] records indicate that wild aurochs might have survived in northwestern [[Transylvania]] until the 14th to 16th century, in [[western Moldavia]] until probably the early 17th century.<ref>{{cite journal |last1=Bejenaru |first1=L. |last2=Stanc |first2=S. |last3=Popovici |first3=M. |last4=Balasescu |first4=A. |last5=Cotiuga |first5=V. |name-list-style=amp |year=2013 |title=Holocene subfossil records of the auroch (''Bos primigenius'') in Romania |journal=The Holocene |volume=23 |issue=4 |pages=603–614 |bibcode=2013Holoc..23..603B |doi=10.1177/0959683612465448 |s2cid=131580290}}</ref><ref>{{cite journal |last1=Németh |first1=A. |last2=Bárány |first2=A. |last3=Csorba |first3=G. |last4=Magyari |first4=E. |last5=Pazonyi |first5=P. |last6=Pálfy |first6=J. |date=2017 |title=Holocene mammal extinctions in the Carpathian Basin: a review |url=http://real.mtak.hu/47261/1/Nemeth_etal_2017_MammRev_Holocene_ext_preprint_u.pdf |url-status=live |journal=Mammal Review |volume=47 |issue=1 |pages=38–52 |doi=10.1111/mam.12075 |bibcode=2017MamRv..47...38N |archive-url=https://ghostarchive.org/archive/20221009/http://real.mtak.hu/47261/1/Nemeth_etal_2017_MammRev_Holocene_ext_preprint_u.pdf |archive-date=2022-10-09}}</ref>

The last-known aurochs herd lived in a [[marsh]]y woodland in Poland's [[Jaktorów]] Forest. It decreased from around 50 individuals in the mid 16th century to four individuals by 1601.

A 2021 study argued that the aurochs possibly survived in northeastern [[Bulgaria]] until at least the 17th century.<ref>{{cite journal |last=Boev |first=Z. |year=2016 |title=Subfossil vertebrate fauna from Forum Serdica (Sofia, Bulgaria), 16–18th Century AD |url=https://www.researchgate.net/publication/308747936 |journal=Acta Zoologica Bulgarica |volume=68 |issue=3 |pages=415–424}}</ref> A horn-core excavated in 2020 in [[Sofia]] was identified as being from an aurochs; the archaeological layer in which it was found was dated to the second half of the 17th or first half of the 18th century, suggesting that aurochs may have survived in Bulgaria until that date.<ref>{{cite journal |last=Boev |first=Z. |year=2021 |title=The last ''Bos primigenius'' survived in Bulgaria (Cetartiodactyla: Bovidae) |journal=Lynx |series=New Series |volume=52 |pages=139–142 |doi=10.37520/lynx.2021.010 |s2cid=246761121 |doi-access=free}}</ref>

== Breeding of aurochs-like cattle ==
{{multiple image |perrow=1 |image1=Hausrindlainz.jpg |caption1=Heck cattle in [[Lainzer Tiergarten]]}}
In the early 1920s, [[Heinz Heck]] initiated a [[selective breeding]] program in [[Hellabrunn Zoo]] attempting to [[Breeding back|breed back]] the aurochs using several cattle breeds; the result is called [[Heck cattle]].<ref>{{Cite journal |last=Heck |first=H. |title=The breeding-back of the Aurochs |doi=10.1017/S0030605300035286 |journal=Oryx |volume=1 |issue=3 |pages=117–122 |year=1951 |doi-access=free}}</ref>
Herds of these cattle were released to [[Oostvaardersplassen]], a [[polder]] in the Netherlands in the 1980s as aurochs surrogates for naturalistic grazing with the aim to restore prehistorical landscapes.<ref name=Lorimer2>{{cite journal |author1=Lorimer, J. |name-list-style=amp |author2=Driessen, C. |year=2016 |title=From "Nazi cows" to cosmopolitan "ecological engineers": specifying rewilding through a history of Heck cattle |journal=Annals of the American Association of Geographers |volume=106 |issue=3 |pages=631–652 |doi=10.1080/00045608.2015.1115332 |bibcode=2016AAAG..106..631L |s2cid=131547744}}</ref> Large numbers of them died of [[starvation]] during the cold winters of 2005 and 2010, and the project of no interference ended in 2018.<ref>{{cite journal |last=Theunissen |first=B. |year=2019 |title=The Oostvaardersplassen Fiasco |journal=Isis |volume=110 |issue=2 |pages=341–345 |doi=10.1086/703338 |doi-access=free}}</ref>

Starting in 1996, Heck cattle were crossed with southern European cattle breeds such as [[Sayaguesa Cattle]], [[Chianina]] and to a lesser extent [[Spanish Fighting Bull]]s in the hope of creating a more aurochs-like animal. The resulting crossbreeds are called [[Taurus Project|Taurus cattle]].<ref>{{cite journal |last=Bunzel-Drüke, M. |year=2001 |title=Ecological substitutes for Wild Horse (''Equus ferus'', Boddaert 1785 = ''E. przewalskii'', Poljakov 1881) and Aurochs (''Bos primigenius'', Bojanus 1827) |journal=Natur- und Kulturlandschaft |volume=4 |pages=240–252 |citeseerx=10.1.1.403.8349 }}</ref> Other breeding-back projects are the [[Tauros Programme]] and the [[Uruz Project]].<ref name=Lorimer2/>
However, approaches aiming at breeding an aurochs-like [[phenotype]] do not equate to an aurochs-like [[genotype]].<ref name=sinding2016>{{cite journal |doi=10.5334/oq.25 |title=The draft genome of extinct European Aurochs and its implications for de-extinction |journal=Open Quaternary |volume=2 |year=2016 |author1=Sinding, M.-H.S. |author2=Gilbert, M.T.P. |article-number=7 |doi-access=free |name-list-style=amp}}</ref>
