Acosmia
Genus of priapulid worms / From Wikipedia, the free encyclopedia
Acosmia is an extinct genus of marine worm from the Cambrian aged Chengjiang biota of Yunnan, China. It is represented by a single rare species, Acosmia maotiania, that reached 45 mm in length and 9 mm in width.[1] It was likely a burrowing animal that fed by deposit feeding.[2] While originally suggested to be a priapulid (penis worm), a 2020 study proposed to be a stem-group ecdysozoan, due to lacking the radial pharygneal armature that characterises modern ecdysozoans, including priapulids.[2]
