There are no living trilobites, but since at least the 1970s, scientists have been imagining how crystal lenses might have worked for the creatures when they were alive (SN: 2/2/74).

Trilobites living 429 million years ago had eyes like modern insects. ... Schoenemann re-examined a fossil of a 1.2-centimetre-long animal called Aulacopleura koninckii.

The fossil in question comes from 429-million-year-old sedimentary rocks in the Czech Republic. It’s a centimeter-long trilobite called Aulacopleura koninckii that split in half as the rock ...

A new study finds that a trilobite species with exceptionally well-preserved fossils from upstate New York has an additional set of legs underneath its head. The research suggests that having a ...

But this trove of trilobite fossils has revealed frustratingly little when it comes to how the Paleozoic animals reproduced across 250 million years of living on ancient Earth.

Johnson found the trilobite, and a companion 14-incher, in an Adams County stream in 1992, while he was living in a mobile home nearby. Trilobites that size can bring $10,000 to $20,000 from ...
