Affinity
Whilst the Bradoriida were traditionally considered as relatives of the modern bivalved arthropod group Ostracoda, the anatomy of their appendages does not support such a relationship; neither are they related to the Cambrian bivalved arthropod group Phosphatocopina.[1] They have been alternatively recovered as stem-group crustaceans, as stem-group mandibulates, or stem-group arthropods, depending on the analysis.[3]
Description
Most bradoriids are only known from their bivalved carapaces, which are small in size, typically up to around 5 millimetres (3⁄16 in) in length. Preserved soft tissues known from some members, such as
Ecology
Bradoriids are thought to have lived either crawling on the seafloor (epibenthic) or swimming close to the seafloor (nektobenthic).[3] Bradoriids are proposed to have been detritus feeders, scavengers, or micro predators of soft-bodied prey.[5]
Occurrence
Bradoriida are geographically widespread, and first occur in the
