Cheloniellida is a taxon (usually referred to as an order[1][2]) of extinct Paleozoic arthropods. As of 2018,[2] 7 monotypic genera of cheloniellids had been formally described, whose fossils are found in marine strata ranging from Ordovician to Devonian in age. Cheloniellida has a controversial phylogenetic position, with previous studies associated it as either a member or relative of various fossil and extant arthropod taxa.[2] It was later accepted as a member of Vicissicaudata within Artiopoda.[3][4][5]
