    Hello again guys,

    I did plenty of research on internet in last 2 days,and i stumble on one article.
    I read that Dr. Mary Higby Schweitzer found soft tissue (blood cells) in 67 million years old T-Rex bone.
    So i really don't understand how is that possible if the bone is million years old,and all living tissue is turn in rock.

    Sorry for bothering,but i don't know where else to ask.

    Some of the "living tissue" wasn't actually tissue at all, but created in reaction to he solvents used I believe. Perhaps some of the tissues were preserved by the sediments where the bones were originally deposited. Then of course you have the thick walls of the bone itself.

    This pretty much addresses any of the creationist sources you have been reading:

    I found it on this sites:

    Dinosaur Shocker | Science & Nature | Smithsonian Magazine
    Scientists recover T. rex soft tissue - Technology & science - Science | NBC News
    T. Rex Soft Tissue Found Preserved

    I tought those were reliable sites...

    Ok - I think I assumed too much and prematurely skipped straight to the end.

    To answer your original question: "So i really don't understand how is that possible if the bone is million years old,and all living tissue is turn in rock.!"
    Answer: No-one else really understands yet, either.

    To quote Mary Schweitzer herself:
    "I can't make any claims for those structures that appear to be like their modern counterparts until the chemistry reveals whether they are molecular remnants of the original structures, even if altered greatly, or if they are some kind of microbial pseudomorph or even some kind of as yet unknown biogeological process unrelated to structures or molecules produced by the dinosaur itself."

    They are reliable sites, what you seem to have missed was the dates of the articles on each. 2006, 2005 and 2005 respectively. This puts all of them as being published before any further research and, the resulting doubts raised, were done on Swhietzers work.

    I recommend this review article. Here are the conclusions:

    The fossil record is capable of intricate and exquisite preservation of originally soft tissues, sometimesextending to the subcellular level. The number of specimens that may also contain informativebiomolecules is not known, but as technology improves in resolution and sensitivity, sequencesfrom proteins other than—or in addition to—collagen may be recovered from very old fossils,and thus may be used to reconstruct molecular phylogenies. If so, recovered molecules originalto these specimens may shed light on attributes not currently attainable from extinct organisms,such as physiological strategies, the rate and direction of molecular evolution, and the acquisitionof molecular novelties that may have favored radiation into new niches. Because molecular preservationhas been linked to morphological preservation (Colson et al. 1997, Hagelberg et al. 1991),fossils that display any type of soft tissue preservation may be productive for future molecularstudies. Thus, it is important to reserve a portion of these specimens for future studies, when technologicalimprovements may increase our ability to recover and sequence original biomolecules.This may entail new field collection methods, such as using aseptic handling techniques, storingunder inert gas, and analyzing these specimens as soon as possible after recovery from environmentswith which they have come into chemical equilibrium. Details of the physiology, biology,and evolution of long-extinct organismsmay soon be amenable to highly technical analyses, openingthe door to greater understanding of other creatures that have shared this planet with humans.Understanding the adaptations of these organisms at themolecular level to times of global climatechange may provide insight on how to facilitate conservation in the near future, when we face thepossibility of equally rapid and dramatic climate shifts.
