In 2022, a film crew working on the Lika Plains near the Adriatic coast of Croatia picked up some remarkable behaviour. A small herd of aurochs had been released into the area a few years earlier, and thermal-imaging video footage showed the bulls responding to the threat of a pack of wolves by forming a semi-circle and facing outwards with their fearsome horns to the front. Cows and calves sheltered behind this defensive shield, along with a group of wild horses, including a foal……..Continue reading….

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. 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.
This painting is thought to have shown an aurochs, although some authors suggested it may have shown a hybrid between an aurochs and domestic cattle, or a Polish steer. Contemporary reconstructions of the aurochs are based on skeletons and the information derived from contemporaneous artistic depictions and historic descriptions of the animal. Remains of aurochs hair were not known until the early 1980s. Depictions show that the North African aurochs may have had a light saddle marking on its back.
Calves were probably born with a chestnut colour, and young bulls changed to black with a white eel stripe running down the spine, while cows retained a reddish-brown colour. 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.
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. 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.
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. The aurochs was one of the largest herbivores 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 1.8 m (5 ft 11 in) in bulls and 1.35–1.55 m (4 ft 5 in – 5 ft 1 in) in cows, while aurochs bulls in Hungary reached 1.6 m (5 ft 3 in).
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. The body mass of aurochs appears to have shown some variability. Some individuals reached around 700 kg (1,540 lb), whereas those from the late Middle Pleistocene are estimated to have weighed up to 1,500 kg (3,310 lb).The aurochs exhibited considerable sexual dimorphism in the size of males and females.
The horns were massive, reaching 80 cm (31 in) in length and between 10 and 20 cm (3.9 and 7.9 in) in diameter. 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. The basal circumference of horn cores reached 44.5 cm (17.5 in) in the largest Chinese specimen and 48 cm (19 in) in a French specimen.
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. 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. Further studies using the aurochs whole genome sequence have identified candidate microRNA-regulated domestication genes.
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.
European Holocene aurochs primarily descend from those that were present in the Iberian Peninsula during the Last Glacial Maximum, with the Holocene also seeing mixing between previously isolated aurochs populations.
