No, not that kind of dating… Rather, ‘dating’ a dinosaur bone dug out of the ground involves a series of processes that allow us to estimate just how long the thing had stuck around on this Earth. This helps us to understand how that species fits into the evolutionary tree of change; when did they first appear and when did the last of their kind walk this Earth? Let’s take a look at the chemistry that allows us to travel 65 millions years back in time.
“Such an exotic name!” you exclaim, “Surely it must be some elusive endangered African species that can only be found in two specific wetlands in the Congo Basin?”
Well, the zebrafish is indeed exotic, but in a different context – the importance of which is far greater than one might bestow upon this little creature.
