Probactrosaurus was a plant-eating dinosaur that lived in China during the Early Cretaceous period. It had a narrow snout and long arms, and it could walk on two or four legs. Scientists think it was an early relative of the duck-billed dinosaurs.2

Probactrosaurus means 'before Bactrosaurus' because the scientist who named it thought it was the ancestor of Bactrosaurus. That idea is no longer accepted.2

It had a small thumb spike, unlike later duck-billed dinosaurs which lost their thumb spikes.2

Probactrosaurus lived about 121 to 99 million years ago, during the Early Cretaceous.1 3

Its fossils were found in the Miaogou Formation in Inner Mongolia, China.2 3

Probactrosaurus had a double row of cheek teeth, with a third row of replacement teeth starting to grow. This helped it grind up plants.2

The first fossils were discovered by a Soviet-Chinese expedition in 1959 and 1960.2

Ñu ngi koy werante ba tey: Scientists are still debating exactly where Probactrosaurus sits on the dinosaur family tree. Some think it is a very early hadrosauroid, while others place it closer to the duck-billed dinosaurs.2
