The Cambrian System, named by English geologist Adam Sedgwick for slaty rocks in southern Wales and southwestern England, contains the earliest record of abundant and varied life-forms.In 2001, Shu et al. suggested that a small group of Cambrian animals which they named Vetulicolia represented the stem group of modern deuterostomes.

Olfactores is a clade within the Chordata that comprises the Vetulicolia, Tunicata (Urochordata) and the Vertebrata (sometimes referred to as Craniata). Olfactores represent the overwhelming majority of the phylum Chordata, as the Cephalochordata are the only chordates not included in the clade.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.However, the fossil appears to be morphologically similar to Vetulicolia cuneata or V. rectangulata from the equivalent lower Cambrian (Series 2, Stage 3) Chengjiang region of Yunnan, China, and less like other members of this enigmatic group (Aldridge et al., 2006).
