Juvenile Hadrosaur Rib Attached To Bone

The hadrosaur, also known as the duck-billed dinosaur, was a herbivorous dinosaur that lived during the Late Cretaceous period. It was characterized by its long, flat beak and rows of closely packed teeth, which it used to efficiently chew tough plant material. The hadrosaur was a large, quadrupedal dinosaur with a bulky body and a distinctive crest on its head, which varied in shape and size among different species. They were also known for their ability to walk on both two and four legs, and for their elaborate communication through honking sounds, which were likely used for social interactions and mating displays. The hadrosaur was one of the most successful and widespread groups of dinosaurs, with fossils found on every continent. Their remains have provided valuable insights into the behavior and ecology of these fascinating creatures.
