Probactrosaurus Characteristics

Probactrosaurus measured 17 - 20 feet (5 - 6 metres) in length and weighed 1,500 kilograms. It had a narrow snout, an elongated lower jaw and double rows of flattened cheek teeth that were suitable for cropping soft vegetation. The duckbills had as many as five rows of teeth in the jaw, one beneath the other. Broken teeth were quickly replaced. Its tail was long, heavy and stiff and held this way by tendons. The hind feet had one toe that faced the opposite direction of its other toes, allowing it to grasp objects.

Probactrosaurus was a herbivorous dinosaur and would have ate a huge amount of plant material to sustain itself. These dinosaurs would eat on all 4 legs (quadrupedal) but when moving fast, would raise up on the hind legs (bipedal) using their tails to balance.

Probactrosaurus means before Bactrosaurus. Yet it is unlikely that this dinosaur was actually an ancestor of the later duck-billed Bactrosaurus. It is very similar to the Iguanodon dinosaur.

Fossils of Probactrosaurus have been found in China. In Eren, 4 fossils of Probactrosaurus Rozhdestvensky with most complete skulls were unearthed.

Probactrosaurus was named by Anatoly Rozhdestvensky in 1966.
