Surprisingly, the split of gastropods and scaphopods is rather late according to our molecular clock analysis (474 MYA; 95% HDP=479520 MYA); this could mean that many Cambrian shells currently regarded to be gastropods were actually members of the gastropod-scaphopod stem lineage.

Gerhard Haszprunar and Jens Bohn (both ZSM) kindly supported preparing the trips. Possession of a single shell is clearly plesiomorphic for Conchifera but this was probably also the case in Calvapilosa, Maikhanella, and Orthrozanclus, fossil taxa inferred to be stem aculiferans52, suggesting that the last common molluscan ancestor may have been single-shelled.
