ደስ ዝብሉ ሓቅታት

1

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

2

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

3

Probactrosaurus lived about 121 to 99 million years ago, during the Early Cretaceous.13

4

Its fossils were found in the Miaogou Formation in Inner Mongolia, China.23

5

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

6

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

ገና ዘከራኽር
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
