三叶虫 - 矩阵化石 - Metacanthina issoumourensis

This is afinely detailed Metacanthina.
Compound eyes in living arthropods such as insects are very sensitive to motion, and it is likely that they were similarly important in predator detection in trilobites.
Trilobite eyes, in contrast, had rigid, crystalline lenses, and therefore no accommodation.

In this specimen all the lenses are preserved. Imagine that each lens bears an individual cornea
lenses separated from each other.
These eyes offered 360-degree vision to the trilobite. To think that this happened 380 million years ago seems impossible.

Compound eyes are a marvel of nature.

Genuine trilobite, well prepared with genal and pygidial spines.

Small restoration . In this specimen the glueing line is less visible in person.

Trilobite is 6,3 cm large, 3,6 cm wide
