Inquicus
Extinct bottle-shaped parasitic worm
Inquicus fellatus is an extinct, bowling pin-shaped gnathiferan[1] worm from the Chengjiang Biota, in what was once a marine environment from the Early Cambrian Yunnan province. Its fossils are found attached to fossils of the worms Cricocosmia and Mafangscolex in either a parasitic or commensalistic relationship.[2]
