Hadrosaurus bone (sliced)

The hadrosaurus is a large, herbivorous dinosaur that lived during the Late Cretaceous period. It is known for its distinctive duck-bill shaped snout and rows of flat teeth, which it used to grind up tough vegetation. The hadrosaurus walked on four legs and had a long, stiff tail that helped it maintain balance while moving. This dinosaur is believed to have lived in herds and may have migrated to find food, as evidenced by the discovery of numerous hadrosaurus fossils in close proximity to each other. Its name, which means "bulky lizard," reflects its size and appearance. The Hadrosaurus is an important species in the study of dinosaur evolution and behavior, and has been the subject of numerous scientific studies and reconstructions.
