Most people think that fossil bones (of which the most well-known examples are those of dinosaurs) must be very, very old - because, after all, they have turned to stone, haven’t they?
But this common picture is misleading. A recent book, co-authored by a world expert on dinosaurs, points out some things about dinosaur bones that are of great interest to creationists. 
For one thing it says:
‘Bones do not have to be "turned into stone" to be fossils, and usually most of the original bone is still present in a dinosaur fossil.’
OK, but even if the actual bone is not replaced by rock minerals, some fossil dinosaur bones are rock-hard, and show under the microscope when cut that they have been thoroughly ‘permineralized’.
This means that rock minerals have been deposited into all the spaces within the original bone. Doesn’t this show that the formation of these fossils, at least, must represent a long time? Think again. The same authoritative work also tells us:
‘The amount of time that it takes for a bone to become completely permineralized is highly variable. If the groundwater is heavily laden with minerals in solution, the process can happen rapidly. Modern bones that fall into mineral springs can become permineralized within a matter of weeks.’
So even a rock-solid, hard shiny fossil dinosaur bone, showing under the microscope that all available spaces have been totally filled with rock minerals, does not indicate that it necessarily took millions of years to form at all.
Now of course if a dinosaur bone is indeed permineralized, it would give it great protection from the normal processes which cause things such as bone to just naturally ‘fall apart’. So a permineralized bone might indeed be anything from a few weeks to (in theory) millions of years old.
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.
‘The nodules prevented water from invading the bones, which for all intents and purposes cannot be distinguished from modern bone.’ 
Those who take Genesis as real history would predict that no dinosaur bone is more than a few thousand years old, so the existence of such totally unmineralized dinosaur bones that have not disintegrated is perfectly consistent with our expectations.
We have previously told you about the unfossilized dinosaur bone which still contained red blood cells and hemoglobin.  Also, we wrote about ‘fresh dinosaur bones’ in Alaska.  Let the evolutionist experts writing this book confirm this:
‘An even more spectacular example was found on the North Shore of Alaska, where many thousands of bones lack any significant degree of permineralization. The bones look and feel like old cow bones, and the discoverers of the site did not report it for twenty years because they assumed they were bison, not dinosaur, bones.’
In summary, therefore:
