The steppe brown bear (Ursus arctos priscus) is an extinct subspecies of brown bear that lived in Eurasia during the Pleistocene period. Fossils of the bear have been found in various caves in Slovakia, particularly those of Vazec, Vyvieranie, Lisková, Kupcovie Izbicka, and Okno.[1]
Description
It may have weighed between 300 and 1,000 kilograms (660 and 2,200 lb), and was possibly more carnivorous than its modern relatives.[2]

Steppe brown bear Ursus arctos “priscus” from the Late Pleistocene of Europe
Abstract
The steppe brown bear U. a. “priscus” is constant but not a common member of the Late Pleistocene paleocommunities. It is not distinct arctoid species, but a large brown bear ecomorph which lived in open environments. Instead to speleoid bears, which disappeared ca. 26-24 ka BP, arctoid bears, thanks to their ecological plasticity, were present in most of the European areas even during the cold phases. The size and diet of these bears were modified under the climate conditions and food availability.
U. a. “priscus” cannot be distinguished genetically, but it differs metrically and morphologically. It was a big sized form with enlarged and broad cheek teeth. Late Pleistocene brown bears, especially those lived before the LGM were more carnivorous than the Holocene and recent brown bear. The steppe brown bear survived till the beginning of the Holocene, where the last relict populations lived around the Baltic and the North Sea decreasing in size and merging genetically with widely distributed Eurasian populations of U. a. arctos.

The type specimen of Ursus priscus GOLDFUSS, 1818 and the uncertain status of Late Pleistocene brown bears
Abstract
From the beginning of the first scientific explorations of caves, the Zoolithenhöhle in Franconia, Germany, was famous for its rich fossil content. In addition to the numerous remains of cave bears and other animals, a skull of a clearly distinct kind of bear was found, originally called Ursus priscus GOLDFUSS, 1818. Three years later, the term Ursus fossilis was introduced along with a published description of the skull, which led to confusion about the adequate designation of the new species. U. priscus was regarded as a contemporary of the cave bear, i.e. Late Pleistocene in age, but the geological age of the find is still unclear even today, and from the overall state of preservation it could be even of Holocene age. Unfortunately, it was not possible to get the permission for dating the skull directly. In this paper a revised study of the skull demonstrates that it is identical to modern U. arctos. The specimen probably represents a female individual. On the basis of this evidence, U. priscus, U. fossilis and its synonyms are invalid terms. The nature of Late Pleistocene brown bears is still not well known.
... Since the first description two centuries ago (Goldfuss, 1818a(Goldfuss, , 1818b, there are still no evident morphological features to describe the steppe brown bear as a distinct form. The overwhelming majority of authors given the great size as a key feature for the Late Pleistocene Eurasian brown bear (Baryshnikov, 2007;Pacher, 2007;Marciszak et al., 2015 and references therein). Although with some exceptions and still not fully clarified nature of this factor, it is general agreement that this character is one of the main features typical for the steppe brown bear. ...
... Finally, we also examined morphometrically the skull of "Ursus priscus", stored in the Natural History Museum in London. This skull was previously studied by various authors (Goldfuss, 1810(Goldfuss, , 1818a1818b, 1823Cuvier, 1834Cuvier, , 1835Lydekker, 1885;Owen, 1846;Middendorf, 1851;Wagner, 1851;Busk, 1879;Reynolds, 1906;Freudenberg, 1914;Rode, 1935;Erdbrink, 1953;Thenius, 1956) and history of those researchers was summarized by Pacher (2007). She concludes that the skull is identical to those in U. arctos, belonged to the female, its stratigraphic position is unclear and the type specimen described by Goldfuss cannot be used as a representative of the Late Pleistocene European brown bear. ...
... She concludes that the skull is identical to those in U. arctos, belonged to the female, its stratigraphic position is unclear and the type specimen described by Goldfuss cannot be used as a representative of the Late Pleistocene European brown bear. With a total length of 350 mm, the Zoolithen bear is rather small-sized specimen when compared with big skulls of Late Pleistocene age (Pacher, 2007). The dimensions well agree with values obtained for Carpathian bears, with the mean of males ca. ...

Fossil Brown Bears of Slovakia
ABSTRACT
The fossil remains of bears are very frequently found in the karst sediments of the
Western Carpathians. Besides cave bears, two taxa of fossil brown bears (Ursus tauba -
c h e n s i s, Ursus arctos priscus) have been present in the Slovak territory during the Late
Pleistocene Period too. Recent European brown bear (Ursus arctos arctos) is appearing in the Western Carpathians Mountains at the beginning of the Holocene or already at the end of the Pleistocene Period respectively. So far, osteological remains of arctoid bears have been described from 23 Slovak locali-ties. The most frequently, these remains belong to the taxon Ursus arctos ssp. or to the recent subspecies Ursus arctos arctos. The fossil findings of brown bears from the Late Pleistocene are less frequent.

THE STEPPE BROWN BEAR CHASED ACTIVE PREDATORS LIKE WOLVES, LIONS, HYENAS, AND HUMANS AWAY FROM THEIR KILLS.
URSUS ARCTOS PRISCUS REACHED A WEIGHT OF 700-800 KG IN BIG MALES AND UP TO 1000 KG IN THE LARGEST INDIVIDUALS:

Reply to the op: the description seems to be updated on wikipedia: Adult males in average would have weighed 700–800 kg (1,500–1,800 lb), with the largest individuals weighing up to 1,000 kg (2,200 lb). It was more carnivorous than a modern brown bear, consuming 50 kg (110 lb) of meat per day. en.wikipedia.org/wiki/Steppe_brown_bearThe Steppe brown bear being attacked by a cave lion is probably female. |

Quote from above post, "Not a unicorn anymore. In this amazing paleoart, an elasmotherium is depicted chasing away a steppe brown bear. As you can see the "new" elasmotherium lacks the iconic horn, resembling more an Indian rhino's horn."
Elasmotherium had a horn, but its shape and size is unknown.

New Data on Large Brown Bear (Ursus arctos L., 1758, Ursidae, Carnivora, Mammalia) from the Pleistocene in Yakutia
Abstract
New finds of brown bear (Ursus arctos L., 1758) fossil remains from the territory of Yakutia, namely, skulls and mandibular bones, have been investigated. The new finds are exceptionally large: most dimensions of these specimens exceed those of the present-day brown bears of Yakutia and even the maximal parameters of the largest individuals of the present-day Eurasian subspecies U. a. beringianus and U. a. piscator. Analysis of various data showed that giant brown bears had inhabited northern Yakutia during the Karginian interstadial in the Late Pleistocene.

I actually forgot how carnivorous this steppe brown bear myself. Actually posted one account myself.

Does it has cave bear DNA and is it related to Ussuri brown bears, East Siberian brown bears and Kamchatka bears?
