Probrachylophosaurus had a short, triangular crest on its head that was taller in the middle and looked like a paddle from the side.1

2

Its name means 'before Brachylophosaurus' because scientists think it was an ancestor of the later dinosaur Brachylophosaurus.1

3

The first fossil of Probrachylophosaurus was found in Montana in 1981, but it was not fully dug up until 2008.1

4

This dinosaur weighed about 4.3 metric tons (4.7 short tons), as heavy as a large SUV.1

5

The most complete skeleton had broken tail bones, which may have been caused by fights with other dinosaurs.1
