A crew helping to build a housing development found the fossils six metres below the surface and called the Royal Tyrrell Museum to report the find. The crew then helped museum staff carefully remove dirt and rock from the prehistoric buried treasure.

Museum curator Francois Therrien said this dinosaur was a teenager when it died and is about eight-metres-long.

He said the fact that much of the skeleton was found intact makes it an important find -- no bones about it.

"When you walk in the badlands of southern Alberta when you find dinosaur bones, nine times out of 10 it will be from a duck-billed dinosaur," he said Wednesday.

"But in terms of finding a complete skeleton -- all the bones connected the way they were in life -- that is really a rare discovery."

So far, the tail and hips of the beast are visible and the skull has been identified.

Last month a pipeline crew in northwestern Alberta uncovered the fossils of a larger and older hadrosaur, a dinosaur that was almost as common during the Cretaceous era as deer are today.
