Vetulicolia é um filo extinto que engloba muitos fósseis do Cambriano. Esses fósseis sugerem que esses animais eram deuterostômios primitivos. O plano corporal consistia de duas partes, uma grande porção anterior com uma grande "boca" e dois conjuntos de cinco estruturas ovais em cada lado que foram interpretadas como sendo guelras e uma parte posterior com sete segmentos.

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.Vetulicola.
