Vetulicolidae is a vetulicolian family from the Cambrian Stage 3 Maotianshan Shale and Sirius Passet Lagerstätte that consists of Vetulicola, Beidazoon, and Ooedigera.

[2] As diagnosed by Aldridge et al. in 2007, the anterior part is said to bear five annulations, and a lateral groove is not mentioned for the family.

However, with and the addition of Ooedigera not all genera possess annulations in the anterior section,[3] and with the re-classification of Yuyuannozoon[1] each genus currently assigned to this family bears a lateral groove.

Vetulicola is known from the Chengjiang fauna, the Guanshan biota (both of the Maotianshan Shales of China), as well as the Mural Formation of the Canadian Rockies.

[1] A 2024 study has found Vetulicolidae (as defined in a 2018 phylogeny)[1] to be a monophyletic group within a paraphyletic Vetulicolia, crownwards of Banffozoa and Nesonektris but basal to Didazoonidae.
