Indian aurochs
The Indian aurochs (Bos primigenius namadicus; ) is an extinct subspecies of aurochs that inhabited West Asia and the Indian subcontinent from the Late Pleistocene to its extinction during the South Asian Stone Age. With no remains younger than 3,800 YBP ever found, the Indian aurochs was the first of the three aurochs subspecies to become extinct, while the North African and Eurasian subspecies survived until the Roman and Modern times, respectively. The Indian aurochs has been found to be ancestral to both the Sanga (Bos taurus africanus) and the zebu (Bos taurus indicus) subspecies of domestic cattle. Description 
The Indian aurochs is known exclusively from fossil and subfossil records, where it shows only minimal morphologic differences to the Eurasian subspecies (B. p. primigenius). The Indian aurochs was probably smaller than its Eurasian counterpart but had proportionally larger horns. Because the range of the aurochs species was continuous from the Atlantic coasts of North Africa and Europe to Bengal, it is uncertain whether there was a distinction or a continuum between the Eurasian, North African and Indian subspecies. The last common ancestor of Indian aurochs and Eurasian aurochs (B. p. primigenius) is estimated to have lived about 150±50 ka BP, based on genetic analyses of living zebus and taurine cattle, the domesticated but heavily interbred descendants of those two aurochs subspecies. Zebu and many Sanga cattle breeds are phenotypically distinguished from taurine cattle by the presence of a prominent shoulder hump. Range 
The author Cis Van Vuure considers the aurochs species to have originated about  in India and spread westwards. Most other authors consider an origin in Africa, where the species' oldest ever remains were found, from ancestors in the Pelorovis genus and a subsequent expansion into Eurasia more likely. A grazing ruminant like all members of his species, the Indian aurochs roamed throughout West and South Asia in the Late Pleistocene and Early Holocene ages. Most remains are from the Kathiawar Peninsula, along the Ganges and Narmada rivers in what is today India. Some bone remains classified as Indian aurochs were also found further south, such as on the Deccan Plateau and along the Krishna River. The most recent remains from presesnt-day southern India, which clearly belong to the Indian aurochs are from Banahalli in Karnataka, with an age of about 4,200 YBP. Further north, the most recent remains date from 3,800 YBP and were found at Mahagara in what is now Uttar Pradesh. The Indian aurochs survived into the South Asian Stone Age, when its natural habitat steadily diminished by human pastoralism and agriculture spreading throughout the region around 5,500–4,000 YBP. Possible predators preying on Indian aurochs are speculated to have been big cats such as lions, leopards and tigers, as well as other predatory mammals such as dholes and even giant hyenas and machairodonts such as Homotherium and Megantereon during prehistoric times. Domestication 
The Indian aurochs was most likely domesticated in the Indus River valley, now the Baluchistan region of Pakistan around 9,000 YBP, with subsequent breeding efforts eventually leading to zebu or indicine cattle. The domestication process seems to have been prompted by the arrival of new crop species from the Near East around 9,000 YBP. Human pastoralism, enabled by domestic cattle, spread throughout the subcontinent around 5,500–4,000 YBP. Secondary domestication events - instances of additional genetic diversity acquired from interbreeding domesticated proto-indicine stock with wild aurochs cows - occurred very frequently in the Ganges basin but less so in southern India. Domestic zebu are recorded from the Indus region since 6,000 BC and from south India, the middle Ganges region, and present-day Gujarat since 3,500–2,000 BC. Discounting gayal and banteng, domestic cattle seem to have been absent in southern China and southeast Asia until 2,000–1,000 BC, when indicine cattle first appeared there. Feral zebu rewilding attempts  

A feral population of zebu cattle is found in the Kuno Wildlife Sanctuary in Madhya Pradesh. The zebu were left there as a potential prey for Asiatic lions and will thus fill the ecological role of their wild ancestors.
