Fossil may solve mystery of what one of the weirdest ever animals ate

A fossil re-examination suggests Hallucigenia, a bizarre Cambrian period animal, may have been a scavenger, feeding on the corpse of a comb jelly. The fossil, found in the Burgess Shale deposits in British Columbia, Canada, shows Hallucigenia spines on a damaged comb jelly, indicating they swarmed on it and fed, probably by suction feeding.
