Biomechanical assessment and the fossil record suggest a sensory function in the anterior glabellar and genal spines in Ordovician raphiophorid trilobites [PDF]
Raphiophorid trilobites were small, abundant, and diverse Ordovician trilobites. One of the most remarkable features of these blind trilobites was a spine projecting from the anterior part of the glabella. The discovery of rows of Ampyx in the Ordovician

Trilobite compound eyes with crystalline cones and rhabdoms show mandibulate affinities
Nature Communications, 2019 Little is known about the internal anatomy of early eyes. Here, Scholtz and colleagues show the internal eye structures from fossils of two genera of trilobites, which support an ancestral apposition eye with crystalline cones in Trilobita and a close ...
