Trilobites Doing an Arthropod Conga Line
One, two, three, stop and put your spines in the air, then back down. Keep going, stay with the beat. Okay, so arthropods probably did not have recreational activities, but it is fun to imagine trilobites doing a conga line.
The number of assigned trilobite species is (to use scientific terminology) a passel. None of them are friendly to Darwinian speculations, such as their sudden appearance in the "Cambrian explosion" and the exceptional optics in some species. Strange about that conga line, though.

Long before the British were famous for queuing, trilobites were showing the way. This collective action is demonstrated in a series of stunning fossil finds of linear trilobite clusters. . . . Trilobites are a group of extinct marine arthropods with a distinct three-lobed body, and some had amazing eye design.The research team were clear that the lines of these creatures were not moved into this position by the water or sediment flowing around them. Rather, their conga line was a deliberate shared action which has been magnificently preserved.
