It’s time for another Trilobite Tuesday. Sometimes fossilized trilobites are little more than flat impressions upon a rock surface. Other times, however, they’re preserved as near-perfect three dimensional reliefs—like this 2.4 in (6 cm) Nankinolithus! This critter, which lived during the Ordovician some 460 million years ago, was found in what is now Scotland.
