Lac La Biche County and Portage College have been making plans for a community celebration to honour three new 2021 Lieutenant Governor of Alberta Distinguished Artists. Given the ongoing COVID-19 related challenges of convening in person, Portage College, Lac La Biche County, and the Lieutenant Governor of Alberta Arts Awards Foundation have moved the celebration to June 11, 2022.
This change has provided a new opportunity: for the first time in the Awards’ history, the host community of Lac La Biche County will celebrate both the 2021 Distinguished Artists and up to 10 new 2022 Emerging Artists.
Her Honour Salma Lakhani, Lieutenant Governor of Alberta, says she is looking forward to honouring the Distinguished and Emerging Artists next summer in Lac La Biche.
“I appreciate the tremendous work that the community has already invested into this special celebration, and I know that the 2022 awards will be well worth the wait. In the meantime, I offer my heartfelt thanks to all of the artists, administrators and patrons across Alberta for everything that you are doing to keep the arts a vibrant part of our lives and our communities during this extraordinary time.”
The organizers look forward to hosting this prestigious event and showcasing Alberta’s diverse arts scene. Their June 2022 plans include opportunities to chat with artists, outdoor community celebrations featuring an Art Walk and Market, art classes and demonstrations, an artist retreat, and a celebratory awards gala.

Alberta paleontologists find dramatic change in bite force as tyrannosaurs matured
Tyrannosaurs are well known as having been ferocious predators at the top of the food chain millions of years ago, but a study led by an Alberta-based researcher shows the reptiles didn’t start out life that way.
François Therrien, curator of dinosaur paleoecology at the Royal Tyrrell Museum in Drumheller, Alta., said the study focused on tyrannosaur teeth and their dramatic change as they matured.
He collaborated with Darla Zelenitsky and Jared Voris of the University of Calgary, as well as Kohei Tanaka of the University of Tsukuba in Japan.
For the study, published this week in the Canadian Journal of Earth Sciences, the researchers examined the lower jaws from the Albertosaurus and Gorgosaurus, types of tyrannosaurs commonly found in Canada that predated the T. rex by millions of years.
“Our fossil records for those two species of tyrannosaurs is excellent,” Therrien said about the collection at the museum.
“We have so many specimens of those … that represent a full growth series from very young individuals that were probably three or four years of age all the way to fully grown adults that were over 20 years of age.”
By examining a wide range of fossils, the researchers were able to see a significant change in tooth size and jaw force once the tyrannosaurs reached about 11 years of age.
Feeding behaviour did not appear to change during the lifespan of the tyrannosaurs, because their jaws were adapted to capturing and seizing prey with their mouths, probably because the forelimbs were too short to grasp food, Therrien said.
“Tyrannosaurs were truly unique when you look at all the theropods,” he said. “They were atypical … because their bite and their skulls were their main weapon for killing prey.”
But what did change, he said, is the size of their teeth and their bite force.
A tyrannosaur at about three years of age was still a deadly predator, but it had smaller blade-like teeth that could only slice through flesh. The bite force, Therrien added, was about 10 per cent that of a fully grown alligator.
That means younger tyrannosaurs ate smaller prey and had to compete with other like-sized predators such as the Velociraptor.
Once tyrannosaurs turned 11, Therrien explained, they went through a growth spurt in which their teeth became larger and wider. By the time the reptiles were fully grown, their bite force was eight times more than that of an alligator.
And that meant their diets also changed.
“These teeth were better adapted for resisting twisting stresses either associated with biting of big prey or even crushing bone.”
Therrien said his study shows that young tyrannosaurs were distinct predators that occupied different ecological niches.
“Young tyrannosaurs were not just scaled-down versions of the mature parents,” he said. “They were creatures that actually had their own lifestyles.”
