Homalocephale is a genus of dinosaur that lived during the Late Cretaceous period, approximately 70 million years ago. It was a small, herbivorous dinosaur known for its unique, flat head and distinctive dome-shaped skull. Fossils of Homalocephale have been found in what is now Montana, USA. This dinosaur belonged to the group of dinosaurs called pachycephalosaurs, which are characterized by their thick skulls. Homalocephale is believed to have used its head for social interactions or possibly for defense against predators. Its body was bipedal, allowing it to walk on two legs while foraging for plants.
