Schmidtiellus Explained

Schmiditellus is an extinct genus of holmiid trilobites from the Cambrian of Poland.[1] [2] As of 2017, a Schmidtiellus reetae fossil from 530 mya, collected in Saviranna in northern Estonia, is the oldest known fossilized eye. The structure is similar to the compound eyes of modern-day dragonflies and bees, but with (~100) ommatidia spaced further apart, and without a lens.[3] [4]
