The fossil, being called a "dinosaur mummy," was impressive not only because of its size and age, but also because its skin and the contents of its gut were still preserved.
While the discovery was a profound moment, researchers hit some bad luck right off the bat when the 15,000-pound block containing the fossil fractured into several pieces during its removal from Alberta's Millennium Mine in 2011.
It was even captured on video by Suncor Energy, which owns the mine:
Darren Tanko, a paleo technician seen in the video, comments, "One of the good things about this, believe it or not, is because it's in smaller pieces it will make preparation go a little faster."
He adds, "This is restorable. Everything broke cleanly and in big pieces. It's unfortunate that this happened but this is restorable."
