Dino DNA after all?

This report seems to be a little breathless and premature, but a pregnant female T.rex fossil has been found to have a medullary bone - a structure containing concentrated calcium for the work ahead - in good shape. This is unusually protected, beuing within the structure of the femur (also, this, hard to find).  Professor Lindsay Zanno at North Carolina State University, "We have some evidence that fragments of DNA" may be preserved in such bones.
