Famous is the force that have the jaws of the hyenas that can reach pressures of 350 kg (600lb)and teeth grinding of hard bones and teeth and hooves. Well, now imagine a hyena twice as big, twice as strong and a powerful jaw twice ... this animal there was Pachycrocuta brevirostris.
Pachycrocuta a genus of prehistoric hyenas. The largest specimen, well-documented part of the species of giant hyenas Pachycrocuta brevirostris. With a height of 1 meter (39 in) and weigh up to 120 kg (250 lb).Un similar in size to a small lioness.
This size would make it the largest of the hyenas that have ever lived. He lived from the Middle Pliocene and Middle Pleistocene, about 3 million and 500,000 years ago.
Found fossils in Eurasia and southern and eastern Africa. In dens, caves used as dens.
Scavenger and a predator could be stubborn and tenacious to deer hunting big and small package was probably a hunter of large animals (up to larger deer and occasionally as Megaloceros). The chance of a scavenger is sensed it was a very big animal not built for chasing prey over long distances. In this aspect would have differed from today spotted hyena, which is a more agile animal that, contrary to his image of the documentaries, also kills his own food. Apparently it was ecologically close enough to the smaller (but still important) in relation perrieri Pliocrocuta never found as fossils contemporaries in the same region.

The Irish elk, Giant deer Megaloceros deer is the largest in history. Like a large deer, his antlers were up to 3.5 m from tip to tip. Although he lived in Europe and much of Asia for half a million years to extinction in recent times, often known as "Irish elk" for the abundant findings of specimens preserved in the peat bogs of Ireland.
The giant deer reached a height of 2.2 m to the cross in the case of males, significantly higher than the largest of the moose. It was a species with strong sexual dimorphism, as females were significantly smaller and slender than the males, in addition to lacking an impressive antlers.
The giant deer grazers were animals that thrived on abundant grass and shrubs in the large, cold plains covering much of Eurasia during the Pleistocene.
Antlers were so large that it required large amounts of calcium and phosphate to form occurring cases of osteoporosis among male Irish elk, so that mortality, already high, increased in bad years.
This fantastic animal became extinct only 7000 years. Were extinguished by changes in the field that were caused by early Neolithic farmers Russian.
