A rare dinosaur discovery in British Columbia has shed light on a lesser-known tyrannosaur species called Gorgosaurus, which was sleeker and quicker than its famous relative, the T. rex. University of Alberta researchers unveiled their findings from the study of a 76-million-year-old partial skull impression, identifying it as belonging to the horned dinosaur Gorgosaurus.
Lead author Colton Coppock described the unique characteristics that distinguished Gorgosaurus and emphasized the significance of this discovery in understanding prehistoric Western Canada. The Royal Tyrrell Museum estimates that Gorgosaurus could grow up to nine meters in length.
The journey to identify the dinosaur began when B.C. resident Rick Lambert stumbled upon a mysterious rock at a campground near Tumbler Ridge. Lambert’s childhood fossil-hunting experience in England, coupled with a serendipitous squirrel encounter, led to the unearthing of the first tyrannosaur skull in B.C. The Tumbler Ridge Museum Foundation verified the significance of Lambert’s find and preserved the original impression in a sandstone block under strict conditions.
Despite the eroded bone material, researchers managed to create a detailed cast of the skull, revealing Gorgosaurus’ unique features, including triangular horns above its eyes. Coppock likened Gorgosaurus to a swifter version of the T. rex due to its lighter build and longer limbs.
The study unveiled new insights into Gorgosaurus’ habitat, suggesting its range extended from eastern B.C. to northern Montana, covering a vast area comparable to modern grizzly bears and cougars. This discovery highlights British Columbia as a promising ground for future dinosaur research, according to Coppock, who emphasized the fossil’s symbolic representation of Earth’s enduring history.
