Several sites of the Middle Cambrian Jince and Buchava formations (Barrandian area, Czech Republic), showing features of Burgess Shale-type preservation, yielded diverse ichnofossils adjacent to non- or poorly biomineralized body fossils of arthropods, and less commonly, acrotretid brachiopods. Based on morphology, Gordia-like, Cochlichnus-like, Planolites-like, Treptichnus-like and Pilichnus-like traces occur with "nondescript" bioturbation. Ethologically, the Gordia-like and Cochlichnus-like traces are interpreted as single-use traces of feeding on microbial halo. Treptichnus-like and Pilichnus-like traces suggest later feeding systems associated also with feeding on microbial halo, and Planolites-like traces likely represent a fortuitous feature.
