Prettige feite

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

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

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

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

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

Probrachylophosaurus lived about 80 million years ago during the Late Cretaceous period.1
