Feeding behavioural patterns have the potential to shed light on evolutionary trends, especially at the critical point of the Cambrian Explosion. In this context, we present specimens of the tubiform priapulid Selkirkia sinica, preserved in situ, collected from the lower Cambrian (Stage 3) Xiaoshiba Lagerstatte, which show the diverse morphology of its intestinal contents within the dark-coloured gut and the formation of faecal pellets. The two digestive modes displayed by S. sinica suggest that it is a putative dietary generalist rather than a typical scavenger as previously thought. Moreover, the asymmetry exhibited by the paired caudal appendages of S. sinica provides direct evidence of the development of dorsoventral (DV) differentiation in Selkirkia, which aids our understanding of the lifestyle of this tubiculous worm.
