    Taxonomy from Fossilworks.org.
    The state of preservation of Magila is mostly poor, which becomes understandable when you consider that Magila was a burrowing crustacean living in the ground. Therefore, a more calcified carapace was not necessary. Only the exceptionally wide claws are mostly well preserved. These probably also served for digging.
    Diagnosis from Garassino & Schweigert 2006, p. 22: “Carapace cylindrical laterally flattened; deep cervical groove strongly directed forward; one or two carinae weak in antennal region; rostrum short and edentate; antennal spine well developed; pereiopods I-III chelate; pereiopod I larger and stronger than pereiopods II-III; pereiopods IV-V achelate; uropodal exopod with diaeresis.”
