Three footprints of fossilized tyrannosaurs have been discovered in Western Canada by a group of scientists. According to the <a href=”http://www.dailystar.com.lb/Life/SciandTech/2014/Jul-25/265197-gregarious-tyrannosaurs-footprints-suggest-so.ashx#axzz38ZOhIloS”>Daily Star</a>, the discovery suggests that the fearsome predators went about hunting in packs. The footprints discoveries are the first ever to be made in close proximity to one another; they are also the clearest evidence thus far which suggests that the tyrannosaur dinosaurs were social rather than solitary animals. The discovery demonstrates three animals moving together in the same direction.
Richard McCrea a member of Peace Region Palaentology Research Center (PRPRC) which led the excavation exercise agrees that the evidence is perhaps the strongest ever to support the claim that the tyrannosaurs were pack animals. Tyrannosaurs are often described as extremely large bi-pedal carnivores with small claw-like front legs and powerful jaws and hind legs. Prior to these discoveries, there was only a single individual tyrannosaur footprint discovery in the whole of the U.S, Canada and Mongolia.
According to a report by <a href=”http://phys.org/news/2014-07-footprints-tyrannosaurs-gregarious.html#”>Physics.org</a>, the discoveries were found in a rock cliff close to the Tumbler Ridge in British Columbia. The three-toed footprints of tyrannosaur were first discovered in 2011 by a local guide and outfitter in what is believed to have been a soft mad some 70 million years ago. Each of the footprints measured about half a meter long, and all belonged to adult animals. Physics.org adds that the footprints predate the Tyrannosaurus Rex, whose ancestors the Daspletosaurus and Albertosaurus are also believed to have roamed the foothills east of the vast Rocky Mountains.
Scientist believed that the discoveries were initially covered up by volcanic ash only to be exposed by the erosion of the cliff many years later. The Daily Star adds that the discovery which has so far witnessed the uncovering of seven footprints is ongoing to find more evidence.
