Researcher Mary Schweitzer discovered original soft-tissue in Dinosaur bone that had not rotted away or turned to stone. She chronicled her struggle to share this data with others here:
“I had one reviewer tell me that he didn’t care what the data said, he knew what I was finding wasn’t possible. I wrote back and said,
“Well, what data would convince you?”
And he said, “None.””
