Single tooth tells a whole story about pre-historic Arabia (The National)
It is easy to imagine the excitement scientists feel when they discover the fossilised skeleton of a long-extinct animal.
Teasing out the bones, the skull and the teeth, and explaining their significance, is the most rewarding experience palaeontologists can have.
Yet complete finds are rare indeed. It is fortunate, then, that even more modest finds can be sources of wonder, whether they are a partial skeleton, a skull or a jawbone with teeth. Or perhaps, even if they are just a single tooth.
