Actually more like political correctness. Remember Mary Schweitzer, the one who found soft tissue inside the femur of a T-Rex?
Have they not also found carbon for C-14 dating of more dinosaur bones? And yet these truths never get widely circulated and published - inconvenient truths that would empty their bank accounts and end many careers.
No, not political correctness.
And, there are no radiocarbon dates for dino fossils.
Mary Schweitzer found traces of dino tissue (blood vessels, cells, and collagen) in the mineral replacement that makes up a T-Rex fossil.
