Happy Trilobite Tuesday!
Pictured is a 3-in- (7.6-cm-) long Nevadia weeksi from the Lower Cambrian of the Western US. With the help of UV lighting, two prominent antennae can be seen on this specimen. Such soft-part preservation is rare in trilobites from this locality.

Itโ€™s Trilobite Tuesday!

The eyes of this Moroccan Ebrenochile are among the largest of all trilobites.

Each ocular surface is covered by hundreds of tiny, geometric lenses! This species inhabited ocean shallows, where keen eyesight was crucial to its survival.

A one-of-a-kind trilobite fossil hints at what and how these creatures ate

The preserved contents suggest the trilobite fed almost continuously and had a gut environment with an alkaline or neutral pH, researchers say.

Itโ€™s Trilobite Tuesday! The fossilized remains of this graceful Dionide from Portugalโ€™s Valongo Formation are both academically significant and an example of natural art. One of the most fascinating Ordovician-age trilobite sites in the world, the Valongo Formation is known for producing jumbo-sized specimens. In fact, one record-holding trilobite from this site is estimated to have been 0.8m long, a world record.
