New Dinosaur Species Brontotholus Harmoni Discovered in Montana
Paleontologists have identified a new species of dome-headed dinosaur, Brontotholus harmoni, from fossils found in northern Montana's Two Medicine Formation. This species, which lived approximately 75 million years ago, is part of the pachycephalosaurid family, known for their thick skull roofs. The discovery was led by Dr. D. Cary Woodruff, who highlighted the significance of the dome's size, making it the third largest known in North America. The fossils provide new insights into the diversity and evolution of dome-headed dinosaurs, which were herbivores with distinctive bony structures on their heads.
