Vetulicola cuneata

Vetulicola cuneata ("wedged-shaped ancient dweller") is a species of extinct marine animal from the Early Cambrian Chengjiang biota of China. It was described by Hou Xian-guang in 1987 from the Lower Cambrian Chiungchussu Formation, and became the first animal (type species) under an eponymous phylum Vetulicolia.

Remarked as "enigmatic creatures" and originally classified as an arthropod, it is recognised as a deuterostome along with other related species, for which a separate class (Vetulicolida), order (Vetulicolata), family (Vetulicolidae) and ultimately a new clade (Vetulicolia) were created based on its name.
