These Three Newly Discovered Mammals Survived the Extinction Event That Wiped Out the Dinosaurs
Recent research has identified three new species of multituberculate mammals that survived the mass extinction event that wiped out the dinosaurs. These species, discovered in Alaska, showcase the adaptability and resilience of mammals in extreme environments. Their unique dental structures suggest they occupied different ecological niches, contributing to their survival during a time of significant ecological change.
- ▪Three new species of multituberculates were discovered in a 70-million-year-old formation in Alaska.
- ▪The species are named Camurodon borealis, Qayaqgruk peregrinus, and Kaniqsiqcosmodon polaris.
- ▪These mammals adapted to extreme arctic conditions, which may have aided their survival after the mass extinction.
