Teeth are sensitive because they evolved from sensory tissue in both ancient vertebrates and ancient arthropods.

(temporal range: 467-443 mio. years ago)

[text from the Wikipedia article, see also link above]

Astraspis ('star shield') is an extinct genus of primitive jawless fish from the Ordovician of Central North America including the Harding Sandstone of Colorado and Bighorn Mountains of Wyoming. It is also known from Bolivia.[2] It is related to other Ordovician fishes, such as the South American Sacabambaspis, and the Australian Arandaspis.
