To me, the simplest explanation fitting the facts seems to be that the commonly-accepted timelines of science (i.e., hundred of million of yeara for dinosaur “evolution”, plate tectonics, mountain formation, and so forth) are simply incorrect and need to be reevaluated. The discovery of viable dinosaur tissue, including blood vessels, blood cells, marrow, and ligaments/tendons, within fossils is yet another piece of evidence against the commonly-accepted timelines.
Where was the viable tissue found?
Do you know the meaning of the word "viable?"
