Primeval Whirl also had issues with safety during its time at Animal Kingdom. Two cast members died after sustaining injuries on the ride, which likely helped influence the decision to shut it down.

Primeval Whirl, the spinning "Wild Mouse" style coaster in Disney's Animal Kingdom, was permanently closed in July 2020 and demolished shortly thereafter due to a combination of maintenance issues, low popularity, and safety concerns. The ride, which opened in 2002 as part of the "DinoLand U.S.A." expansion, was often criticized by fans for feeling like a "cheap carnival ride" that didn't meet Disney's high standards for immersive theming. Operationally, it was a headache; the ride suffered from frequent mechanical breakdowns and had a controversial safety history, including two tragic employee accidents in 2007 and 2011. Disney shifted it to "seasonal operation" in 2019 before deciding that the cost of a full refurbishment wasn't worth the investment. As of 2026, the site is being cleared as part of the massive "Tropical Americas" project announced at D23, which will replace DinoLand with new attractions themed after Indiana Jones and Encanto, officially making the era of the spinning dinosaurs "extinct" to make way for more modern storytelling.
