Seems Hollywood got it wrong. The Tyrannosaurus rex or T. rex wasn't the terrifying lone hunter that's scared us to death in movies.

Latest scientific evidence seems to show that T. rex hunted in gangs of at least three and probably more, making it a far more deadlier predator.

Paleontologists said a study of the first fossil tyrannosaurid trackways ever discovered that revealed three sets of fossil footprints close together is clear evidence that T. rex were "gregarious," that is, they operated in packs rather than alone as is commonly thought.

The study was published in a PLOS One paper, "A Terror of Tyrannosaurs." PLOS is an open access peer-reviewed scientific journal published by the Public Library of Science.

Paleontologists said a series of footprints, also called "trackways," reveal certain things that bones alone may not. These include the T. rex's gait, how fast it ran and what it was traveling with at the time.

The trackways with the T. rex footprints are located in northeastern British Columbia. The footprints are longer than 19.5 inches and all point in the same direction, and are within 8.5 meters of each other.

Paleontologists said that since T. rex were typically few in numbers, it's highly unlikely that three solitary tyrannosaurs just happened to be in the same place at the same time walking in parallel.

By analyzing the gait of each T. rex from one footprint to the next, scientists think the animals were traveling around 3.9 mph to 5.3 mph.

T.rex was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Most scientists now agree that Tyrannosaurus rex was an opportunistic carnivore, acting as both a predator and a scavenger.

T. rex was the largest known tyrannosaurid and one of the largest known land predators. Over 50 specimens of Tyrannosaurus rex have been identified.
