Welcome to 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. Discovered at a dig site near Jorf, Morocco, the specimen pictured here reveals an amazing colony of ornate 1-in- (2.5-cm-) long Devonian lichids.

It's time for Trilobite Tuesday! In recent years, a variety of well-preserved trilobites have been uncovered from Northern Ontario’s Silurian-age Thornloe Formation—including this species of Diacalymene, which has not yet been scientifically described. Some examples can reach more than 2.4 in (6 cm) in length.
