Шаблон:Year nav topic20 This list of fossil arthropods described in 2016 is a list of new taxa of trilobites, fossil insects, crustaceans, arachnids and other fossil arthropods of every kind that have been described during the year 2016, as well as other significant discoveries and events related to arthropod paleontology that occurred in the year 2016.

Arachnids

Research

• A study on the phylogenetic relationships of the Eocene tick Ixodes succineus is published by Dunlop et al. (2016).
• A study on the phylogenetic relationships of the Carboniferous species Archaeometa nephilina and Arachnometa tuberculata is published by Selden, Dunlop & Garwood (2016), who interpret these taxa as harvestmen rather than spiders.

Trilobites

Research

• Queues of the trilobite Trimerocephalus chopini are described from the Devonian (Famennian) of Poland by Błażejowski et al. (2016), who interpret these queues as representing mass migratory chains.
• Disarticulated exoskeletons of the phacopids belonging to the species Omegops cornelius preserved within a nautiloid conch are described from the Devonian Hongguleleng Formation (China) by Zong, Fan & Gong (2016), who interpret the fossils as indicating that the trilobites had moulted within the living chamber of a dead nautiloid.
