Vetulicolia is an extinct phylum erected by Shu "et al." (2001), encompassing several early-Cambrian fossil forms. They suggest that these animals were early deuterostome s.

Background Vetulicolians are a group of Cambrian metazoans whose distinctive bodyplan continues to present a major phylogenetic challenge.
