For one day, the University of Calgary, Canada was transformed into a giant human Jurassic park. Students, professors, employees, families and children invaded the campus wearing dinosaur costumes of all kinds (from T-Rexes to Triceratops), giving life to one of the most surreal and spectacular events of the year. The initiative, organized to celebrate the 60th anniversary of the university, had a specific objective: to conquer the Guinness World Records for the largest number of people dressed as dinosaurs gathered in the same place.

The new world record: 682 dinosaurs together
The target was exceeded by a large margin. The official count certified the presence of 682 participants in dinosaur costumes, beating the previous world record of 468 people, set in 2025 in Florida by the Cox Science Center and Aquarium. The Guinness judge’s announcement sparked an explosion of enthusiasm on campus: applause, shouts, hugs and music accompanied the proclamation of the new world record.
“Rex’s Jurassic Jamboree” becomes a collective party
The event, called “Rex’s Jurassic Jamboree,” was designed as a celebration open to the entire university community. Students, teachers, former students and citizens participated, all strictly disguised. Among the costumes we saw gigantic inflatable T-Rexes, colorful one-piece suits and dinosaurs of every possible species. Some participants were completely hidden inside huge inflatable structures, leaving only their shoes visible.

Very strict rules for obtaining Guinness
To obtain official certification, the organizers had to follow very precise rules imposed by Guinness World Records. It wasn’t enough to wear a simple accessory: each participant had to be completely recognizable as a dinosaur. Organizers had started registration days before the event and carefully checked each costume. Dragons, fantasy creatures or incomplete disguises were excluded. The goal was to meet the required criteria for the record to the letter.
A curious record that goes around the world
After the official confirmation of the record, hundreds of dinosaurs started dancing to the tune of We Are the Champions by Queen, transforming the campus into a giant collective party. According to university officials, the most exciting moment came when the number “682” was announced publicly. In a few seconds the silence transformed into an overwhelming celebration, with moved and smiling people everywhere. And obviously it only took a few hours for images of Canadian “dinosaurs” to begin circulating on social media and in the international media, transforming a university party into a global phenomenon.
