For the commune in France, see Chancia.
Chancia is an extinct genus of Cambrian trilobite.
It was a "fast-moving epifaunal detritivore" from Canada (British Columbia, specifically Burgess Shale, and Newfoundland) and the United States (Idaho, Pennsylvania, Utah, and Vermont).
[1] Chancia was a particle feeder.
Its major characteristics are a normal glabella but an enlarged cephalon due to a pre-glabellar field in front of the glabella, as well as developed eye ridges, medium-sized genal spines, and an extremely small pygidium.
