GRANDE PRAIRIE, Alta. -- Dig it.

Paleontologists are busy in northwestern Alberta after a pipeline crew uncovered a fossil of a dinosaur.

The fossil skeleton is of the creature's tail, and experts believe the prehistoric beast may have been up to 10 metres in size.

Paleontologist Matthew Vavrek calls the find this week near Spirit River "a significant fossil discovery."

The challenge now is to carefully recover the fossil and perhaps find other parts to help determine the type of dinosaur.

People working on the excavation include members of the Philip J. Currie and Royal Tyrrell museums.
