How about [http://news.nationalgeographic.com/news/2005/03/0324_050324_trexsofttissue.html National Geographic]? The [http://news.bbc.co.uk/2/hi/science/nature/4379577.stm BBC] has a good article too. The NG article explains the why of breaking the bone:

<blockquote>The dinosaur was under an incredible amount of rock," said Jack Horner, a curator of paleontology at the museum. "When it was collected, the specimen was very far away from a road, and everything had to be done by helicopter.</blockquote>

<blockquote>"The team made a plaster jacket to get part of the fossil out, and it was too big for the helicopter to lift. And so we had to take the fossil apart.</blockquote>

<blockquote>"In so doing, we had to break a thighbone in two pieces. When we did that, it allowed [Schweitzer] to get samples out of the middle of the specimen. You don't see that in most excavations, because every effort is made to keep the fossil intact," said Horner, a co-author of the study.</blockquote>
