It's Trilobite Tuesday! Trilobites, while commonly seen fossilized as single individuals, were highly social animals—gathering together to mate, molt, or feed. On occasion, fossils are unearthed featuring multiple trilobites on a single slab, like these ornate 1-in- (2.5-cm-) long Devonian lichids.
