Abstract

New material of the rare arthropod Acanthomeridion, including Acanthomeridion anacanthus sp. nov., is described from the lower Cambrian Chengjiang biota, Yunnan Province, China. The material includes a specimen with paired gut diverticulae along the length of the mid-gut that resemble structures in other artiopodan arthropods such as naraoiids. Previous phylogenetic analyses have indicated a petalopleuran/xandarellid affinity for Acanthomeridion, but our analysis resolves Acanthomeridion outside the main subclades of the Artiopoda (Aglaspidida + Trilobita, Nektaspida, Cheloniellida + Xenopoda, Conciliterga, Petalopleura (including Xandarellida)) as the most basal artiopodan. http://zoobank.org/urn:lsid:zoobank.org:pub:3563C327-EF9C-4A49-B200-417CE5D95D60
