 One of the most widespread and diverse animal groups of the Cambrian explosion is a clade of stem lineage arthropods known as radiodonta, first reported in 1892. Radiodonts are now one of the best known early animal groups with excellent representation in the fossil record. They are ubiquitous components of conservat logger statin from the Cambrian and the early Ordovician. These large swimmers were characterized by a segmented body bearing laterally oriented flaps and a head with a distinct radial oral cone, a pair of large frontal appendages adapted for different feeding modes, compound eyes on stalks and prominent head carapaces. Radiodonts inform on the paleoecology of early animal communities and the steps involved in Uarthrapod evolution. For families within radiodonta have been established. The raptorial predator families Anomalocorididae and Amplectobaluidae were dominant early in the evolutionary history of radiodonta, but were later overtaken by the Megadiverse and widespread her deity, which had.
