It’s not every day Calgary sees over 600 people in dinosaur costumes take over a University campus.
On April 11, 2026, students, staff, alumni, and community members gathered at the University of Calgary to celebrate its 60th anniversary.
And this was not any ordinary celebration.
The day included an attempt to break a Guinness World Record for the largest gathering of people dressed up as dinosaurs.
A full dinosaur takeover
Now you’re probably wondering, why dinosaurs?
The University of Calgary’s athletic teams are known as the Dinos, with the official mascot being Rex O’Saurus, the Tyrannosaurus Rex.
And the world record attempt also had some pretty specific requirements. To be counted, participants had to be fully dressed in dinosaur costumes from head to toe, including a full dinosaur body and headpiece that clearly represented a real dinosaur. Partial costumes or accessories did not count.
According to the University of Calgary, the previous record for the largest gathering was held by Cox Science Centre and Aquarium in Florida, where 468 people dressed as dinosaurs gathered last summer.
And UCalgary did not just beat that number; they completely blew past it, with 682 dinosaur-costumed participants, they officially set a new Guinness World Record!
According to the University of Calgary, the moment the record was confirmed, the atmosphere on campus completely shifted. What started as a fun, chaotic attempt quickly turned into a full-on celebration.
A full day of celebration
Beyond the record attempt, the Community Day celebration was packed with activities that brought the city together.
Attendees heard from a lineup of special guests, including University of Calgary President Ed McCauley and Chancellor Jon Cornish, as well as Olympic medallists Catriona Le May Doan, Mark Tewksbury, and Dr. Hayley Wickenheiser.
Across campus, there were food trucks, giveaways, live entertainment, and family-friendly activities everywhere you turned.
This event was more than just a large dinosaur gathering. It was a celebration of community, connection, and 60 years of meaningful history at the university.
And while the dinosaurs are probably what everyone will talk about first, the real takeaway is how the city came together, embraced the moment, and helped turn a university milestone into a standout memory.
