We humans have been studying dinosaurs for a long time, but that doesn't mean we have learned all that we can about them. 

One way to learn more about these ancient creatures is to look at their fossils under a microscope. 

Of course, looking at dinosaur bones under microscopes is not as easy as it sounds. 

This video by PBS Eons explains the process as well as the results of examining dinosaur bones under high magnification.
