It happened in Canada this week when the backhoe laid bare an extremely rare find, the fossil of a dinosaur millions of years old.
A whole 35-foot dinosaur may be slumbering inside the rock a construction worker hit while clearing a site in the town of Spirit River. He was making way for an oil pipeline.
The company stopped work and called around to find someone who knew something about dinosaurs.
Word got to paleontologist Matthew Vavrek, who went out to inspect. He wasn’t expecting to see what he found on the side of sandstone boulder.
