Paleontology in Saskatchewan

Before a T. rex can tower over museum visitors or a Triceratops can show off its huge horns, dinosaur fossils must first be painstakingly reconstructed, cleaned, fit together and even painted.

For U.S. restorationist Lauren McClain, the process is like putting together a giant 3D puzzle.

A Paris auction house will seek to sell in October the world's biggest known example of the dinosaur triceratops, known as "Big John", with the spectacular skeleton on show to the public beforehand, organizers said Aug. 31.
