A fearsome über-wolf that once roamed the snowy plains of Alaska may hold warning for the fate of large carnivores today, its discoverers say. The creature's massive jaws and powerful hulking frame made the wolf a force to be reckoned with, yet molecular and physical evidence indicate that the animal's specialized features doomed it to extinction around 12,000 years ago.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://sciencenow.sciencemag.org/cgi/content/full/2007/622/1">These features indicate that the ancient wolf was a "hypercarnivore" able to tear apart and consume large prey, such as mammoth, bison, and horses. Genetic analysis revealed that the wolf was not an ancestor of today's wolves.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://sciencenow.sciencemag.org/cgi/content/full/2007/622/1">
