Tyrannosaurus rex may have hunted in packs

New fossil evidence unearthed in Canada suggests that the meat-eating behemoth may not have hunted alone.
If the sight of one Tyrannosaurus rex charging through the foliage is enough to instill fear in to your heart then imagine coming face to face with a whole gang of the infamous meat-eaters.

Palaeontologists believe that they may have dispelled the idea that T rex was a lone predator after finding fossilized footprints in British Columbia of multiple individuals all traveling in the same direction at the same time.
"Itís probably about the strongest evidence you can get that these animals travelled in groups," said excavation leader Richard McCrea.

Dating back 70 million years, the prints would have originally been made in soft mud before hardening and eventually turning to rock.

"Thereís an advantage in numbers," added Michael Ryan, curator of vertebrate paleontology at the Cleveland Museum of Natural History. "You can take down large prey if youíve got three versus one."

Ya it was a common theory but this finding confirms it. How terrifying that must have been. I would love to see a video of them taking down some kind of bronteosaur. With David Attenborough narrating of course

You would not be afraid very long, then snap! I would love to (safely) see an actual T Dragon. Bring on the Clones.

Three sets of tracks found hardly proves that they hunted in packs, they could have separately been following the scent of a wounded animal/lizard, or off to a picnic.

I always thought they did. They're just scaled up velociraptors. Besides, in their four year growth stages they filled ecological niches that species of different sized mammals fill today.Their prey was species of saurischian and ornithischian dinosaurs in all the different sizes of their own short growth stages.

Of course they hunted in packs. How else would they fight teepee building Sasquatch? This is British Columbia we are talking about. But yea I watched a documentary somewhere last year they were talking about t-rex hunting in packs.

Would be awesome to witness a pack of Rexxes clicking and whistling back and forth while they ambushed their prey

They're just scaled up velociraptors. . scaled up?! Velociraptors were the size of CHICKENS! .

. scaled up?! Velociraptors were the size of CHICKENS! . They come in all sizes.Dromaeosaurids were small to medium-sized dinosaurs, ranging from about 0.7 metres (2.3 ft) in length (in the case of Mahakala) to over 6 metres (20 ft) (in Utahraptor and Achillobator).[16][17] Some may have grown larger; undescribed specimens of Utahraptor in Brigham Young University collections belonged to individuals that may have reached up to 11 m (36 ft) long, though these await more detailed study.[18] Large size appears to have evolved at least twice among dromaeosaurids; once among the dromaeosaurines Uta...

Hmm I dont know but footprints can be from a path where allot of T-Rexes passed. But that doesnt mean they passed there in packs. It is equally possible there is allot of time between the prints made. Mud doesnt turn into stone over night.
