Sensory features on the armored exoskeletons of ancient fish may be the reason why humans have teeth that are sensitive to cold and other extremes.

Although dentin-lined tubules in Eriptychius resembled invertebrate sensilla, they contained dentine and had features indicating sensory capability, including open pulp cavities and large dentine ...
