Maiasaura was a large, plant-eating hadrosaurid dinosaur, often referred to as a “duck-billed” dinosaur because of its broad, flat snout. It lived during the Upper Cretaceous Period, around 65 to 70 million years ago. In 1978, paleontologists discovered a remarkable nesting site in the Two Medicine Formation near Choteau, Montana, providing valuable insight into the species’ behavior and care for its young.

This dinosaur had a short, wide, toothless bill, while its jaws contained hundreds of closely packed teeth for grinding tough vegetation. It featured a small bony crest between its eyes, a long, pointed tail, and strong hind legs that were longer than its forelimbs—suggesting it could move both on two and four legs. Maiasaura reached about eight meters in length and could weigh up to four metric tons, taking roughly seven to eight years to reach full adulthood.
