The Vetulocystidae are a very recently described family of two species from the Chengjiang Lagerstatte of the Lower Cambrian of China. Shu et al ., 2004. The authors interpreted them as an anatomical link between the Vetulicolia on one hand and the homalozoans on the other. Like Vetulicolia, they have a distinctly bipartite body plan.The eumetazoans in the Chengjiang biota are herein divided into 11 major groups: Annelida, Euarthropoda, Brachiopoda, Chordata, Cnidaria, Ctenophora, Hyolitha, Lobopodia, Priapulida, Radiodonta, and Vetulicolia. These groups represent, for the most part, well agreed upon animal phyla.Vetulicolia bezeichnet einen ausgestorbenen Tierstamm, der 2001 von Shu u. a. erstellt wurde; er umfasst mehrere unterkambrische Fossilformen. Die taxonomische Zuordnung der Vetulicolia ist nach derzeitigem Stand der Wissenschaft (2008) umstritten. D.G. Shu et al. sprechen sich dafür aus, dass es sich bei diesen Tieren um frühe Neumünder (Deuterostomia) handelt.
