Heme compounds in dinosaur trabecular bone

"ABSTRACT

Six independent lines of evidence point to the existence of heme-containing compounds and/or hemoglobin breakdown products in extracts of trabecular tissues of the large theropod dinosaur Tyrannosaurus rex. These include signatures from nuclear magnetic resonance and electron spin resonance that indicate the presence of a paramagnetic compound consistent with heme. In addition, UV/visible spectroscopy and high performance liquid chromatography data are consistent with the Soret absorbance characteristic of this molecule. Resonance Raman profiles are also consistent with a modified heme structure. Finally, when dinosaurian tissues were extracted for protein fragments and were used to immunize rats, the resulting antisera reacted positively with purified avian and mammalian hemoglobins. The most parsimonious explanation of this evidence is the presence of blood-derived hemoglobin compounds preserved in the dinosaurian tissues.

Well, there you have it. Let's not beat about the bush, creationists have been caught lying again. The dino blood is nothing more than fossil bone that is consistent with heam groups left behind by blood. Interesting, but not a single blood cell was recovered.

From the second site in the OP:

However, when the dinosaur bone has been prevented from being invaded by mineral-rich water, one would expect that over �millions of years�, even locked away from all bacterial agents, dinosaur bone would, in obeying the laws of thermodynamics, just disintegrate from the random motions of the molecules therein.

Huh?
