Brachylophosaurus was a mid-sized hadrosaurid dinosaur that roamed North America around 76.5 million years ago during the Late Cretaceous Period, with fossils found in modern-day Montana (Judith River Formation) and Alberta (Oldman Formation). Adults could grow up to 9 meters in length and weigh approximately 7 metric tons, making them substantial herbivorous dinosaurs of their ecosystem.
One of the most distinctive features of Brachylophosaurus is its bony crest, which formed a flat, paddle-like plate atop the skull, setting it apart from other hadrosaurs. This dinosaur also had unusually long forelimbs and a wider upper jaw beak, adaptations that supported its specialized feeding behavior. Its cheeks and unique teeth allowed it to efficiently chew plant material, a sophisticated trait rare among reptiles but common in ornithischian dinosaurs.
These adaptations highlight Brachylophosaurus as an advanced herbivore capable of processing tough vegetation, demonstrating the evolutionary innovations of hadrosaurid dinosaurs. Its combination of size, crest structure, and feeding efficiency makes it one of the most fascinating members of the Late Cretaceous herbivorous dinosaur community.
