ProBactrosaurus was an early member of the family known as the Iguanodon s. In fact, it is kind of a cross between those dinosaurs and the duck-billed hadrosaurs. Like other duck-billed dinosaurs, it had hundreds of teeth packed closely together to form what is called a dental battery. These batteries were used to grind tough plant fiber into mushy pulp so that it could be digested easier. It could walk on either two or four legs.
ProBactrosaurus represents an evolutionary step between Iguanodon and Bactrosaurus It had a number of features found on both Iguanodon s and the later hadrosaurs, and it marks an important step in the evolution of two important families. The type specimen is considered by some to be a juvenile based on the large size of its feet. |
