The fossils belong to 500-million-year-old blind water creatures, known to scientists as "vetulicolians" (pronounced: ve-TOO-lee-coal-ee-ans).Background Vetulicolians are a group of Cambrian metazoans whose distinctive bodyplan continues to present a major phylogenetic challenge. Thus, we see vetulicolians assigned to groups as disparate as deuterostomes and ecdysozoans. This divergence of opinions revolves around a strikingly arthropod-like body, but one that also bears complex lateral structures on its anterior section interpreted ...V etulicolians are among the most perplexing of the many enigmatic animals that have now been recovered from Cambrian Lagerstätten. Originally regarded to be unusual arthropods (), they have subsequently been reinterpreted as deuterostomes, either basal (Shu et al. 2001) or more derived (e.g. Gee 2001a; Lacalli 2002).As noted by Lacalli (2002), if the interpretation that vetulicolians are ... ….
