did you know that the eyes here - with the shading brim - are thought to be the first clear evidence of an animal active in the daytime? you only need an eye shade if you're active when the sun is out. these utterly alien eyes were the first to bask in the light of the same sun we still walk under

Welcome to Trilobite Tuesday! Pictured is the Devonian-age phacopid trilobite Erbenochile erbeni. Not only does this Moroccan species feature towering 0.8-in (2-cm-) high eye stacks—each topped by a unique shading brim—but it also has a row of intimidating spines that run along its axial lobe.
