Kodymirus vagans is an extinct species of the arthropods from the Lower Cambrian .
features
Kodymirus vagans was about 80 mm long. The headstock was pentagonal in outline and had dorsal kidney-shaped eyes. The five pairs of lateral extremities were single-branched, strongly prickly and growing in size towards the rear. The trunk consisted of twelve segments that became narrower in the direction of the caudal spine and ended in pleural spines that became longer in the direction of the caudal spine. The tail sting ( telson ) was pointed and long.
Location
Numerous completely and partially preserved fossils of this type, 24 of them with preserved extremities, were found in the Barrandium (Prague Mulde) in the Czech Republic .
Systematics
The species was counted due to the similarity with the horseshoe crabs to the sub-tribe of the jaw-claw carrier (Chelicerata) and classified in the order Aglaspidida . According to van Roy 2006, however, the species does not meet all characteristics for the Aglaspidida in the strict sense and is therefore listed as Aglaspidida-like .
