Kockurus is a problematic genus of Cambrian arthropod, known from the Czech Republic, which bears some resemblance to the eurypterids, aglaspidids and chelicerates.[1] It is diagnostic of a small and low-diversity fauna endemic to the area, which dwelt in brackish waters.[1]
Along with the very closely related Kodymirus, it is an enigmatic Cambrian arthropod whose precise taxonomic affinity is uncertain, but is best considered to be a stem-group or ally of the aglaspidids.[2]
