No. I've heard the paper was in the works for a while, but they results are new 
for public release. The samples came from a T. rex femur which was intact when 
discovered, with hollow interior that was not infilled with minerals. 
Schweitzer dissolved the calcium minerals in the bone to get the soft tissue. 

No word on protein sequences or DNA. I'd expect protein sequences to follow, 
but not DNA, which doesn't hold up well.
