When archaeologists recover fossils from the Earth, there is frequently a conundrum regarding making sense of what the bones actually mean. It is very rare to find an intact piece of bone, much less a whole skeleton. Which bone is it? Where does it go? And of course, what kind of life did this animal live? Was it a mammal or a lizard, was it a meat or plant eater, and how did it live exactly? These questions can frequently be answered from the teeth.
