'''Olenidae''' is a family of [ptychopariid](/source/ptychopariida) [trilobite](/source/trilobite)s. Some genera, ''[Balnibarbi](/source/Balnibarbi_(trilobite))'' and ''[Cloacaspis](/source/Cloacaspis)'', are thought to have evolved a [symbiotic](/source/symbiosis) relationship with sulfur-eating bacteria from which they derived nutrition.<ref name=Fortey00b>{{Citation|last1=Fortey |first1=Richard |author-link=Richard Fortey |title=Olenid trilobites: The oldest known chemoautotrophic symbionts? |journal=[Proceedings of the National Academy of Sciences](/source/Proceedings_of_the_National_Academy_of_Sciences) |volume=97 |issue=12 |pages=6574–6578|date=June 2000 |pmid=10841557 |pmc=18664 |doi=10.1073/pnas.97.12.6574|bibcode = 2000PNAS...97.6574F |doi-access=free }}</ref>
