(Bryan Jones/Flickr/CC BY-NC-ND 2.0) This is how we know that trilobites had compound eyes like insects, consisting of clusters of photoreception units called ommatidia, each with its own photoreceptors and lenses. Examinations of broken sections of the fossilized lenses reveal a crystalline material made of calcite. The trilobite fossil described by Oldrich Fatka and Michal Szabad is subtle, but significant.

Apparently in trilobite-fossils the lenses are always calcitic, whatever the facies they had been found in. This would be a topic worthwhile to investigate more closely. An almost completely calcitic lens would have provided the advantage of a high refractive index (n ω = 1.640–1.660 n ε = 1.486, sea water n = 1334). In water the difference ...Fossils in general, and trilobites in particular, are rarely in top quality, finest state of preservation when they are found.

In 1985, the Ordovician trilobite genus Isotelus, which occurs in southwestern Ohio, was named the official state invertebrate fossil.

Because trilobites had wide diversity and an easily fossilized exoskeleton an extensive fossil record was left behind, with some 17,000 known species spanning Paleozoic time. The study of these fossils has facilitated important contributions to biostratigraphy, paleontology, evolutionary biology and plate tectonics.
