The University of Calgary just celebrated its 60th birthday. And to mark the occasion, it broke the Guinness World Record for the largest gathering of people dressed as dinosaurs. On April 11th, 682 people gathered for the campus Community Day, and they were all dressed as their favorite dinos. By doing so, they beat the previous record of 468, set by Cox Science Center and Aquarium in West Palm Beach, FL, on January 10th, 2025.

Friedman (@RonSFriedman) April 14, 2026 To get people into the spirit, the university administration invited students, faculty, staff, alumni, donors, and locals to a Rex’s Jurassic Jamboree, encouraging everyone to wear their favorite dinosaur costume. The event included free barbecue and a meet and greet with Olympians with ties to UCalgary. “People showed up in some fabulous onesies [and] blow-up dinos where you could not see any part of the person inside except for their feet,” University of Calgary Vice-Provost Verity Turpin told the Canadian Broadcasting Company. The University of Calgary Smashed the Previous Records Set in 2019 and 2025 Once everyone arrived, they danced to songs by a local band. And they sang We Are the Champions by Queen while waiting for a Guinness adjudicator to make the official count. “As soon as we heard Guinness say, ‘Six,’ we knew we broke the record,” Turpin shared. “And no one listened to anything after that. We were all screaming and hugging each other. It was awesome.” “The old record is extinct,” UC’s president and vice-chancellor Ed McCauley joked during an interview with the Calgary Herald. “This is just a great example of the University of Calgary and our Calgary community coming together to set a world record.” The original record for the largest gathering of people dressed as dinosaurs was set on January 26, 2019, in Los Angeles, California.
