Vetulicolia.

Conway Morris and Selden, 2015. Banffia is a genus of animals described from Middle Cambrian fossils. The genus commemorates Banff, Alberta, near where the first fossil specimens were discovered. Its placement in higher taxa is controversial. It is considered to be a member of the enigmatic phylum Vetulicolia . †Vetulicolia (8 Cambrian species of fossil) Cephalochordata - (lancelets, 30 species) Vertebrata (vertebrates - animals with backbones; 57,739 species) Agnatha (jawless vertebrates; 100+ species) Myxini or Hyperotreti (hagfish; 65 species) Conodonta (Conodonts) Hyperoartia (Lampreys) †Cephalaspidomorphi (Paleozoic jawless fish)Vetulicola is a extinct genus of marine animal discovered from the Cambrian of China. It is the eponymous member of the enigmatic phylum Vetulicolia, which is of uncertain affinities but may belong to the deuterostomes.

Some of its features are also consistent with other structures, such as a gut or a coelomic cavity.ConclusionsPhylogenetic analyses resolve a monophyletic Vetulicolia as sister-group to tunicates (Urochordata) within crown Chordata, and this holds even if they are scored as unknown for all notochord characters.
