Fun facts

Albertadromeus had a long shin bone that helped it run fast to escape predators.1

Its name means 'runner from Alberta' because scientists think it was built for speed.1

The lower part of its fibula (a leg bone) was fused to the tibia, a rare feature that helped identify it as a new species.1

It lived about 77 to 76 million years ago during the Late Cretaceous.1

Albertadromeus shared its home with big predators like Daspletosaurus and Troodon.1

Only a few bones of Albertadromeus have been found, including leg bones and vertebrae, but no skull.1
