The Burgess Shale fossil beds in the Canadian Rockies are famous for showing us some of the creepiest evolutionary dead-ends to ever grace the planet. They conjure up underwater scenes of many-legged spiky creatures scuttling beneath gigantic spider shrimp, but a recent find in the Burgess Shale suggests a more pastoral landscape: fields of waving tulip-shaped creatures, each about 8 inches high.

These newly discovered filter feeders, named Siphusauctum gregarium by their discoverers, have been found in clumps of over 65, and appear to have fed by sucking water through their bodies and extracting food particles.
