Slaying the Iron Maiden: Mary Schweitzer's Vulnerability

Clickable Biomaterial Fossils Papers List

Paleontologist Mary Schweitzer, the Iron MaidenCo-author of a Triceratops soft tissue paper, Kevin Anderson challenges Dr. Mary Schweitzer's claim that biological iron has the ability to preserve dinosaur biological material for tens of millions of years. On Real Science Radio, Bob Enyart and Dr. Anderson, a molecular biologist, describe Schweitzer's two-year experiment, which she then extrapolated to 68 million years, and they discuss the many physics and depositional factors that falsify the extraordinary claim of the famed paleontologist, whom RSR amiably refers to as the Iron Maiden. See the conclusion at

* Challenges to and discussion of the iron preservation model:
- 2020 Microscopy Today published the Armitage and Solliday discovery of Triceratops blood clots, veins, valves, and nerve fibers, concluding "that free iron was unavailable... in these Triceratops bones..."
- 2019 More T. rex Soft Tissues at ICR by paleobiochemist PhD Brian Thomas, "Fenton chemistry preservation mechanism suffers big flaws. For one, Fenton reactions overwhelmingly break apart more biomolecules than they bind together. But the biggest flaw is the fact that so many researchers have found a flood of evidence for original proteins themselves, not only the more resistant chemicals that a fraction of Fenton reactions would produce. Thus, even if Fenton reactions produced resistant molecules, then so what? Results continually show the presence of original biochemicals..."

* Factors that Lead to Tissue Decomposition: The folowing list is based on a presentation given by an industry colleague of Dr. Anderson, ICR's Brian Thomas in August 2013 at a Pittsburgh creation conference. Bob Enyart was in attendance considering the apparent contradiction of extant biological tissue in 100-million year-old fossils and wondering how many different rescue devices evolutionists would eventually appeal to in addressing these many factors of degradation:
