Geological Time: Early Cambrian, (~525 million years ago) Size (25.4mm=1 inch): 50 mm long by 23 mm across on a 35 mm by 63 mm . Fossil Site: Chengjiang Maotianshan Shales - Quiongzhusi Section, Yu'anshan Member, Heilinpu Formation, Mafang Village, Anning, Kunming, Yunnan Province, ChinaAccording to a long-standing theory, the origin of chordates may be found in transformed larvae of sea-squirts ( tunicates ). Adult tunicates are sessile, but their larvae are motile, and have some features found in early vertebrates. The process of paedomorphosis, where juvenile features are retained in the adult, is the proposed mechanism.Shu et al. placed Vetulicola in the new family Vetulicolidae, order Vetulicolida and phylum Vetulicolia, among the deuterostomes. Shu (2003) later argued that the vetulicolians were an early, specialized side-branch of deuterostomes. Dominguez and Jefferies classify Vetulicola as an urochordate, and probably a stem-group appendicularian.The new metazoan, tentatively referred to Vetulicolia, was discovered in the Middle Cambrian Pierson Cove Formation of the Drum Mountains, Utah, USA.
