Честно утащено из ФБ.Век живи - век учись. Белый медведь охотился на пингвинов. Именно на пингвинов, не гагарок. Просто это был другой медведь 🙂
«Somewhere in Pleistocene Patagonia, two bears (Arctotherium tarijense) fight over a dead penguin. It is a basic fact of zoology taught to children that polar bears and penguins do not coexist- but in the Pleistocene, the subantarctic regions of South America would've had both creatures side by side and it is likely that the bears preyed on penguins on occassion.
Arctotherium tarijense was the southernmost bear ever to exist, and so the closest there ever was to a southern polar bear, but it was not closely related to modern polar bears; instead, it was a tremarctine, or short-faced bear. It was in the same size range as today's brown bears which made it a pretty respectable ursid but not as big as the giants of its linneage- the north American Arctodus simus and the earlier, South American Arctotherium angustidens which might be the largest of all known bears.
A. tarijense was apparently highly carnivorous, and a study found it had the agility and balance to be a very capable hunter, but it is also likely it scavenged a lot off the kills of the Patagonian big cats such as Smilodon, the Patagonian panther (Panthera onca mesembrina) and the puma.
Like all bears it would've had a very keen sense of smell and may have sniffed out carrion from very far away, as well as perhaps following the movements of vultures and condors from afar.
A. tarijense inhabited not only cold, windy, barren regions of southern Patagonia but also forests and mountains, being apparently a very adaptable species.
