The tortuous path of distortion and deception required to say that a young-earth chronology is a legitimate scientific interpretation of the facts is so tangled and incoherent as to make refutation not just a never ending chore but pointless.
The recent discovery that under the right conditions the hemoglobin (converted to hematite) acted as a cellular structure preservative is exciting and informative. What seemed impossible has been shown to be possible. No, actual biological cells, blood and DNA have not been recovered, that is a lie perpetuated by unscrupulous creationist authors selling books or ad space on their blogs. What is found are microstructures, traces and chemical markers, a level of fossilization thought beyond hope, that offer a deeper view into the lives of these ancient animals.
It is a great example of how science works. What was assumed impossible was later revealed to be possible through the scientific method and increases in technology. Creationists who have actually read the findings know they are grossly misrepresenting the work and the evidence.
