Discovery of Lokiceratops rangiformis dinosaur in northern Montana

A newly identified dinosaur called Lokiceratops rangiformis lived about 78 million years ago in what is now northern Montana. It was a plant-eating dinosaur with a unique set of horns on its head, including the largest frill horns ever observed on a dinosaur. The horns were likely used for display rather than defense. The discovery sheds light on the rapid evolution of new dinosaur species in a limited geographical region.
