Putting a Face on a Mystery Dinosaur

Putting a Face on a Mystery Dinosaur
In 1965, paleontologists made a strange discovery. They found a massive pair of dinosaur limbs - huge clawed front arms, stretching several meters across. But that was all they found. Now, a team led by one of Canada's most eminent paleontologists has matched arms to body and rescued critical parts of the fossil from dinosaur poachers. The story of the fossils is as strange as the dinosaur itself.
