I was wondering about that when a great discovery was made, one I'm sure you can't give any answer to :
* "65-million" Year Old T. rex Soft Tissue: North Carolina State University discovered original biological tissue from a supposedly 65-million year old Tyrannosaurus Rex thighbone, with transparent and pliable blood vessels containing red blood cells! See these photos at Smithsonian Magazine and at MS-NBC, and then see a 2007 Nat'l Geographic report, a 2009 Nat'l Geo. confirmation, and the Hell Creek Formation excavation site worked by famed paleontologist Jack Horner of Montana State University. In 2011 ten leading universities and institutes including Harvard, the University of Manchester, and the University of Pennsylvania published in PLoS One, a peer-reviewed journal, that they have verified that presumed dinosaur material is indeed original biological tissue from a dinosaur! Combined with the research on Egyptian mummies that established 10,000 years as an upper limit for how long such biological molecules could survive, this is another reason why creationists refer to dinosaurs as missionary lizards. Interestingly, PZ Myers recently mocked RSF and repeated the now widely-discredited evolutionist hope that the "soft-tissue" dinosaur finds were "biofilm" contamination from bacteria. But as 60 Minutes shows and Bob Enyart sums it up, "This is dinosaur."
* Iron-clad "Dinosaur-era" tissue from "70-million year old" Mosasaur: In this peer-reviewed report by researchers including from Lund University in Sweden and Southern Methodist University in Dallas, scientists confirm another biological tissue discovery using sophisticated techniques to rule out modern contamination, bio-film, etc., concluding that original biological collagen exists in a small bone from an extinct marine reptile called a Mosasaur. Yet according to a report in Science Magazine as it relates to the discoveries of dinosaur tissue, scientists calculate the maximum survival time of collagen not in millions but in thousands of years.
