Species[13][14]

Archaeopriapulida is a group of priapulid-like worms known from Cambrian lagerstätte.[15] The group is closely related to, and very similar to, the modern Priapulids.[16] It is unclear whether it is mono- or polyphyletic.[17] Despite a remarkable morphological similarity to their modern cousins,[18] they fall outside of the priapulid crown group, which is not unambiguously represented in the fossil record until the Carboniferous.[19] They are probably closely related or paraphyletic to the palaeoscolecids; the relationship between these basal worms is somewhat unresolved.[17]
