![]() ![]() Known for their exceptional size, specialized bone-cracking back teeth, and the propensity of preying on larger herbivores, they have earned a reputation as one of the largest most notable predators in the Americas.ĭespite their reputation, their demise has been theorized to be due to other dog-like species that out-compared dire wolves or spread diseases.Īlso Read: Prehistoric "Hell Ant" Encased in Amber Seen Biting Its Prey for Over 99 Million YearsĬheck out more news and information on Paleontology on Science Times. The dire wolf or Aenocyon is a mythologized carnivore. But what we know about their evolutionary history has been limited to what we can see from the size and shape of their bones and teeth." Angela Perri from Durham University says, "Dire wolves have always been an iconic representation of the last ice age in the Americas. This means dire wolves were likely to be ill-equipped to adapt to the drastic climatic changes during the end of the ice age.ĭr. direwolf Incredible footage of what appears to be an extinct species of wolf called the dire wolf some will say that it is just a huge Gray or Timberwolf I think possibly otherwise why is. "A legendary symbol of Los Angeles and the La Brea Tar Pits, (dire wolves) has earned its place among unique species that went extinct at the end of the Pleistocene epoch," says Robert Wayne, a distinguished UCLA professor of ecology.Ī collaboration of 49 researchers from nine countries, including the US, Australia, the UK, and Germany, published their findings that unlike other canid species that repeatedly migrated between Eurasia and North America, dire wolves evolved only in North America for millions of years.ĭespite the overlap between grey wolves, coyotes, and dire wolves as recent as 10,000 years ago, there is no interbred evidence. This shows us that dire wolves evolve in isolation from their Pleistocene ancestors. Unfortunately, in spite of hybridization across Canidae, there is no scientific evidence showing gene flow between the two species. ![]() However, relatively little information is known about their evolutionary history.īy sequencing five genomes from sub-fossil remains from 13,000 to 50,000 years ago, scientists uncover the truth behind dire wolves.Ĭheck Out: Here's Why Crocodiles Look Nearly the Same for 200 Million Yearsĭespite the morphological similarities between grey wolves and dire wolves, the latter diverged from the living canids 5.7 million years ago. The prehistoric dire wolf prowled through most of America most notably in Los Angeles over 11 millennia ago.Ī study published in the journal Nature, led by researchers from the University of California Los Angeles, reports that dire wolves are, in fact, distinct from their previously thought relatives - the gray wolf.ĭire wolves are considered as one of the most widespread and common large carnivores in the Pleistocene era. Known for their exceptional size, specialized bone-cracking back teeth, and the propensity of preying on larger herbivores, they have. More than thirty subspecies of Canis lupus have been recognized, including the dog and dingo, though gray wolves, as popularly understood, only comprise. The dire wolf or Aenocyon is a mythologized carnivore. 2 The wolf ( Canis lupus b PL: wolves ), also known as the gray wolf or grey wolf, is a large canine native to Eurasia and North America. But scientists reveal that dire wolves were real once upon a time. Global wolf range based on IUCN's 2018 assessment. Even if this speculation never leads to a certain knowledge of the reason for the Dire Wolf’s extinction, the information we have about the Dire Wolf continues as researchers maintain their investigation of the Dire Wolf and its life in the prehistoric tundra.Dire wolves have always been the stuff of fantasy as it was recently made famous by the series Game of Thrones. When the larger prey became scarce as the glaciers receded, the Dire Wolf’s build did not allow it to adapt to hunting smaller, lighter, quicker prey. Still other scientists believe warmer climates and less big game led to its complete extinction along with the Mastodon, the Giant Ground Sloth and the Woolly Mammoth. But again, this theory still leaves the question of why the Dire Wolf did not withstand man while the Gray Wolf flourished. Along with fire, clothing, and weapons, man may have also brought disease. Some experts feel that man, in competition with the Dire Wolf’s larger prey, contributed to the Dire Wolf’s eventual extinction as they competed with each other. Still these theories leave the question of why some species died out and others survived. Climatic change may have played a significant role Dire Wolf’s demise, but some scientists speculate that, along with this climate change, a large comet may have contributed to the Dire Wolf’s untimely disappearance. Maybe even in as few as 100 to 1000 years at the end of the Pleistocene Era. Evidence suggests that the Dire Wolf’s extinction happened quickly.
